Don’t Sell Your Laptop Without Following These Steps

Before selling or trading in your laptop, it is important to prepare the device for its new owner as this will help ensure all of your personal data remains safe.

In an age when every day, a new version of a laptop with better features, sleek design, and improved performance hits the market, it is no wonder that you also wish to buy a new laptop to achieve excellence in performance and enjoy new features.

You have money, you can buy a new laptop, great! But what about your previous laptop? If you are thinking of selling it, then…stop.

If you think selling a laptop is all about saving your data, finding a seller, and selling it, then you need to think again. It goes beyond this! It is not all about getting a fair price, but also saving your personal information and private data from reaching a stranger – that might cost you a lot if that stranger is fraudulent or malicious.

Before selling or trading in your laptop, it is important to prepare the device for its new owner. This can be done by taking several simple precautions that will help ensure all of your personal data remains safe.

1 Save Your Important Data

It goes without saying that your first step should be keeping a backup of your essential data, including personal and work-related files and folders, containing documents, presentations, emails, plans, strategies, or anything else that you have prepared with so much hard work.

If you don’t want to see your data slipping from your fingers, then this should be your number one step.

You can save your data on a data drive or upload it to a reliable cloud service. Or send them to your own email address (well, this is my favorite way of saving my data!). Do whatever suits you, but saving data is a must before selling your laptop.

However, this can only work if you have a few GB of data. In case you have terabytes of data then owning a workstation from companies like Western Digital (WD) is a good way to go.

2 Delete Passwords Permanently

Nobody wants the passwords of important accounts to get leaked. Full stop! But have you ever thought about how to save your passwords before giving your laptop? What — did you just say you can do it by signing off from all your accounts and deleting history and cookies? Ah, I wish it was really that easy, but it is not. 

Where technology has brought so much ease into our lives, there it has also become a trouble in many ways — like this one. Unfortunately, some software can extract passwords even if you log out from your accounts.

That is where you should act smartly if you don’t want someone to sneak into your Facebook and start sending weird messages through your accounts to your friends. It could trigger so many controversies – eh. So, cut iron with iron.

You can also use apps such as password generators. One such example is the IPVanish password generator which lets users delete passwords permanently from their browsers. If you wish to do that manually, follow these easy steps:

For Chrome browser: First, open Chrome and click on the three-dot menu icon located in the top right corner. Then select “Settings” and click on “Passwords” under Autofill. Here you will find a list of all the websites that have saved credentials, along with their usernames and passwords.

Select an entry to see the details, then click on the three-dot menu icon next to it and select “Remove.” You’ll be asked to confirm by clicking “remove” again; once confirmed all login information for that website will be deleted from your computer. (Read more on Google.)

For Firefox: First, launch the Firefox browser on your device. Then, click the ‘Menu’ icon (three lines in the upper right corner) and select ‘Options’ or ‘Preferences’. In this menu, you will see a section for ‘Logins & Passwords. You can then scroll through all of your saved logins and passwords until you find the one that needs to be deleted.

For Safari Browser: To begin, open up the Safari browser on your computer and click the ‘Safari’ menu at the top left corner. In that menu option, select ‘Preferences’ and then navigate to the ‘Passwords’ tab. (Read more on Mozilla.)

Here you will see a list of all of your stored passwords that have been saved by Safari. To delete one or more of these passwords, simply check off each box next to each entry that you wish to remove and hit delete in the bottom right corner. (Read more on Apple.)

3 Format the Drive

Have you saved your important data? Great! Now, what about data that is still on your laptop? Obviously, you can’t leave it like this for others to see your private information and confidential data. No, just deleting data files and clearing Recycle Bin or Shift + Delete might not work. It can still keep the issue of data leakage and privacy breaches there. 

In this condition, most people go for drive formatting that cleans up your laptop and makes it data free. However, this method works if your files are overwritten and you are using a solid-state drive (SSD) with TRIM enabled.

With HDD or TRIM disabled, you would have to overwrite the hard drive if you don’t want cheap software to recover your data – yes, even after formatting. It is very easy to recover a permanently deleted file through even cheap software. So, be safe than sorry!

4 Prepare Your Laptop for Selling

Once you are done saving your information, next, it is time to prepare your laptop for sale at a good price. The price of your gadget also depends on its model, functionalities, current market price, and a lot more. However, improving the outer condition, and speed, upgrading Windows, and enhancing the memory storage can enhance the price of your laptop. 

So, work on the following things to get good bucks:

  • First, install the latest Windows to make your buyer happy. You can vow anyone with the latest functionalities already installed on the laptop, so that person wouldn’t have to go through all the trouble. It is a good chance to impress a buyer.
  • Second, work on the speed of the laptop. Half of the work is already done when you delete files and data. So, reset the laptop to speed it up.
  • Clean up your laptop, please. Don’t take your laptop to a buyer with all the lint or dust trapped between keys and scratches on the screen. You can remove lint or dust with a brush and change the screen cover. This simple work can make a lot of difference.
  • Lastly, visit a laptop expert and ask for a thorough inspection so that you can rectify if there are any internal faulty parts.

Whitepaper: Best Practices for MITRE ATT&CK Mapping

CISA uses ATT&CK as a lens through which to identify and analyze adversary behavior. CISA created this guide with the Homeland Security Systems Engineering and Development Institute (HSSEDI), a DHS-owned federally funded research and development center (FFRDC), which worked with the MITRE ATT&CK team.

Whitepaper

CASCADE

CASCADE is a research project at MITRE which seeks to automate much of the investigative work a “blue-team” team would perform to determine the scope and maliciousness of suspicious behavior on a network using host data.

The prototype CASCADE server has the ability to handle user authentication, run analytics, and perform investigations. The server runs analytics against data stored in Splunk/ElasticSearch to generate alerts. Alerts trigger a recursive investigative process where several ensuing queries gather related events. Supported event relationships include parent and child processes (process trees), network connections, and file activity. The server automatically generates a graph of these events, showing relationships between them, and tags the graph with information from the ATT&CK project.

Metta

Metta is an information security preparedness tool. This project uses Redis/Celery, Python, and vagrant with VirtualBox to do adversarial simulation. This allows you to test your host based instrumentation but may also allow you to test any network based detection and controls depending on how you set up your vagrants. The project parses YAML files with actions and uses Celery to queue these actions up and run them one at a time without interaction.

Sandbox Scryer

Sandbox Scryer is an open-source tool for producing threat hunting and intelligence data from public sandbox detonation output. The tool leverages the MITRE ATT&CK Framework to organize and prioritize findings, assisting in assembling IOCs, understanding attack movement and hunting threats. By allowing researchers to send thousands of samples to a sandbox for building a profile for use with the ATT&CK technique, Sandbox Scryer can help solve use cases at scale.

Bug in Toyota, Honda, and Nissan Car App Let Hackers Unlock & Start The Car Remotely

The majority of major automobile manufacturers have addressed vulnerability issues that would have given hackers access to their vehicles to perform the following activities remotely:-

  • Lock the car
  • Unlock the car
  • Start the engine
  • Press the horn
  • Flas the headlights
  • Open the trunk of certain cars made after 2012
  • Locate the car

Flaw in SiriusXM

SiriusXM, one of the most widely used connected vehicle platforms available on the market, has a critical bug in its platform that affects all major vehicle brands.

There is a particular interest among security researchers in the area of connected cars, like Yuga Labs’ Sam Curry. In fact, he’s the one who was responsible for discovering a security hole in the connected cars of major car manufacturers during his routine research.

There are a number of car manufacturers who use Sirius XM telematics and infotainment systems as a part of their vehicle technology.

Affected Car Brands

Here below we have mentioned the brands’ names that are affected due to this critical bug in SiriusXM:-

  • Acura
  • BMW
  • Honda
  • Hyundai
  • Infiniti
  • Jaguar
  • Land Rover
  • Lexus
  • Nissan
  • Subaru
  • Toyota

Vulnerability Analysis

During the process of analyzing the data, it was found that there is a domain (http://telematics(.)net) that is used during the vehicle enrollment process for the remote management of Sirius XM.

The flaw is associated with the enrollment process for SiriusXM’s remote management functionality which results in the vehicle being tampered with.

There is not yet any technical information available about the findings of the researchers at the present time, since they haven’t shared anything in detail.

Upon further analysis of the domain, it becomes apparent that the Nissan Car Connected App is one of the most plentiful and frequently referenced apps in this domain.

In order for the data exchanged through the telematics platform to be authorized, the vehicle identification number (VIN) only needs to be used. The VIN of the vehicle can therefore be used to carry out a variety of commands by anyone who knows the number.

The next step would be to log in to the application later on, and then the experts examined the HTTPS traffic that came from a Nissan car owner.

Researchers discovered one HTTP request during the scan in which they conducted a deep analysis. 

It is possible to obtain a bearer token return and a “200 OK” response by passing a VPN prefixed ID through as a customerID in the following way:-

Car App

Using the Authorization bearer in an HTTP request, researchers attempted to obtain information about the user profile of the victim and, as a result, they successfully retrieved the following information:-

  • Name
  • Phone number
  • Address
  • Car details

In addition to this, the API calls used by SiriusXM for its telematics services worked even if the user did not have an active subscription with SiriusXM.

As long as the developers or owners are not involved in the process of securing a vulnerable app, it is impossible to guarantee the security of that app. This is why they should be the only ones who can issue security updates and patches.

Recommendations

Here below we have mentioned the recommendations made by the security analysts:-

  • Ensure that you do not share the VIN number of your car with unreliable third parties.
  • In order to protect your vehicle from thieves, it is imperative to use unique passwords for each app connected to the vehicle.
  • Keep your passwords up-to-date by changing them on a regular basis.
  • Keeping your system up-to-date should be a priority for users.

A New Linux Flaw Lets Attackers Gain Full Root Privilege

Category: Linux SecurityDISC @ 10:41 am

The Threat Research Unit at Qualys’ has revealed how a new Linux flaw tracked as (CVE-2022-3328),  may be combined with two other, seemingly insignificant flaws to gain full root rights on a compromised system.

The Linux snap-confine function, a SUID-root program installed by default on Ubuntu, is where the vulnerability is located.

The snap-confine program is used internally by snapd to construct the execution environment for snap applications, an internal tool for confining snappy applications.

Linux Flaw Let Attackers Gain Full Root Privilege

The newly discovered flaw, tracked as CVE-2022-3328, is a race condition in Snapd, a Canonical-developed tool used for the Snap software packaging and deployment system. 

The issue specifically affects the ‘snap-confine’ tool that Snapd uses to build the environment in which Snap applications are executed.

“In February 2022, Qualys Threat Research Unit (TRU) published CVE-2021-44731 in our “Lemmings” advisory. The vulnerability (CVE-2022-3328) was introduced in February 2022 by the patch for CVE-2021-44731).” reads the post published by Qualys.

“The Qualys Threat Research Unit (TRU) exploited this bug in Ubuntu Server by combining it with two vulnerabilities in multipathd called Leeloo Multipath (an authorization bypass and a symlink attack, CVE-2022-41974, and CVE-2022-41973), to obtain full root privileges”.

The CVE-2022-3328 weakness was chained by the researchers to two other flaws in Multipathd, a daemon responsible for looking for failed paths. Particularly, in several distributions’ default installations, including Ubuntu, Multipathd runs as root.

Two Vulnerabilities Impact Multipathd

The device-mapper-multipath, when used alone or in conjunction with CVE-2022-41973, enables local users to gain root access. 

In this case, the access controls can be evaded and the multipath configuration can be changed by local users who have the ability to write to UNIX domain sockets.

This problem arises because using arithmetic ADD rather than bitwise OR causes a keyword to be incorrectly handled when repeated by an attacker. Local privilege escalation to root may result from this.

Together with CVE-2022-41974, the device-mapper-multipath enables local users to get root access. Further, due to improper symlink handling, local users with access to /dev/shm can modify symlinks in multipathd, which could result in controlled file writes outside of the /dev/shm directory. Hence, this could be used indirectly to elevate local privileges to the root.

Notably, any unprivileged user might get root access to a vulnerable device by chaining the Snapd vulnerability with the two Multipathd vulnerabilities.

“Qualys security researchers have verified the vulnerability, developed an exploit, and obtained full root privileges on default installations of Ubuntu,” Qualys said.

On Ubuntu default installations, Qualys security researchers have confirmed the vulnerability, developed an exploit and got full root access.

Although the vulnerability cannot be used remotely, the cybersecurity company issues a warning that it is unsafe because it can be used by an unprivileged user.

Data of Israeli Employees from 29 Logistics Firms Sold Online

Category: Data Breach,data securityDISC @ 10:33 am

The 50GB worth of data is currently being sold on two clear web forums with a price tag of 1 BTC per database.

A group of hackers has posted a trove of approximately 50GB of data for sale on two online forums and a Telegram group. The data was posted on 26 and 27th November 2022. This was revealed to Hackread.com by researchers at VPNMentor.

A probe into the incident revealed that the data belonged to 29 Israeli transportation, logistics services and forwarding firms. Researchers believe that the hackers breached a software provider’s single point of failure, gained unauthorized access to these logistics firms’ supply chains, and exfiltrated a trove of personal data and shipping records.

50 GB of Israeli Firms’ Data on Sale

Hackers have posted the stolen data for sale. Visitors can buy a complete employee and customer information dataset from the targeted companies. The per-database rate is 1 BTC, which equals $17,000. An analysis of the graphics associated with these posts revealed that the data is part of a Black Friday Sale.

Previously, when some Israeli delivery firms were targeted in cyberattacks, the Israeli government’s cyber agencies named Iranian threat actors as the perpetrators. However, it is unclear if the same actors are responsible in this instance.

Details of Leaked Data

According to VPNMentor’s blog post, exposed data includes contract details and shipment information of the affected Israeli firms. The hackers have listed 1.1 million records for sale on different online forums. It seems like they have shared a small sample of data.

Whether 1 record represented 1 person or 1.1 million people were impacted in this data breach couldn’t be determined. The exposed information includes full names, addresses, and contact numbers.

Researchers were unsure whether the exposed addresses were work or home addresses. Customers’ exposed data includes full names and shipping details (sender and receiver’s addresses, number of packages, contact numbers, etc.).

Data of 1 Million Israeli Employees from 29 Logistic Firms Sold Online

Possible Dangers

These records can be exploited to intercept packages or blackmail/threaten courier firms’ employees into handing over valuable shipments. Threat actors can use personal data such as full names or contact details to target people with scams and phishing attacks.

Customers of these firms should be wary of suspicious SMS messages and calls and do not share personal information via phone. They should reveal sensitive data only to a trusted source only when necessary.

Essential Business Knowledge for InfoSec Professionals

Category: Security ProfessionalDISC @ 11:14 pm

The role of InfoSec professionals has morphed into a critical business function. One should expect getting involved in “business” discussion often, and at increasing higher levels of business structure up to board of directors. Understanding and speaking business language is more important than ever for the success of any InfoSec professionals. Knowing basic business lingo is also crucial for effective communication inside an organization.

Lack of basic business knowledge and common business terminology hinders success and progress. 

I have started creating a body of knowledge for basic business skills required for success of security professionals and elevating their status in the business hierarchy. Following are eight major domains of essential business knowledge for information security professionals.

  • DOMAIN 1 – Essential Business Terminology for InfoSec Professionals
  • DOMAIN 2 – Business Communication for InfoSec Professionals
  • DOMAIN 3 – Funding Requests and Managing InfoSec Budget
  • DOMAIN 4 – Working with Vendors and Partners
  • DOMAIN 5 – Building Alliances, Collaboration to Advance InfoSec Goals
  • DOMAIN 6 – Excellence in InfoSec Customer Service, Knowing and Serving Customers
  • DOMAIN 7 – Creating Business Value with InfoSec
  • DOMAIN 8 – General Soft Skills to Succeed as InfoSec Professional

what are major skill gaps?

ISACA published a report on “State of Cybersecurity 2022” in which they presented their findings on the global workforce. The most striking of all the findings is Figure 14 of the report showing major skill gaps among security professionals.

At the top of these skill gaps is “soft skills” that includes communications, flexibility, leadership and others. This is similar to what we have been talking about creating a body of knowledge for Core Cybersecurity Skills and Practices. Please see a screenshot of Figure 14 from the ISACA report (the report is available for download at https://www.isaca.org/go/state-of-cybersecurity-2022).

Spyware Vendor Variston Exploited Chrome, Firefox and Windows 0-days

Category: Spyware,Zero dayDISC @ 10:30 am

A Barcelona-based company, a spyware vendor named Variston IT, is exploiting flaws under the guise of a custom cybersecurity solutions provider.

On 30th November, Google’s Threat Analysis Group (TAG) reported that a Barcelona-based company, actually a spyware vendor, named Variston IT has been exploiting n-day vulnerabilities in Chrome, Firefox, and Microsoft Defender under the guise of a custom cybersecurity solutions provider. 

In their detailed technical report, TAG explained that Variston IT had been using their exploitation framework called Heliconia to install spyware on the targeted devices. The researchers at Google received an anonymous submission to Chrome’s bug reporting program which brought to their attention the exploitation framework.

Heliconia actually contains three separate exploitation frameworks. One of them is used to compromise the Chrome renderer bug so that it can escape the walls of the app’s sandbox and run malware on the operating system.

Another one is used to deploy malicious PDF documents containing an exploit for Windows Defender (a built-in antivirus engine in the newer versions of Windows).  The last framework is for compromising Windows and Linux machines by using a set of Firefox exploits.

A manifest file in the source code provides a product description (Image: Google)

In its report, the tech giant observed that the Heliconia exploit is successful against Firefox versions 64 to 68, which suggests that it was created and used as early as December 2018 when Firefox 64 first came out.

Google, Microsoft, and Mozilla fixed the vulnerabilities in 2021 and early 2022. They further stated that, although they had not detected active exploitation, it is likely that the vulnerabilities had been exploited before they could be fixed.

The CHRISTMA EXEC network worm – 35 years and counting!

Category: MalwareDISC @ 11:32 am

Forget Sergeant Pepper and his Lonely Hearts Club Band, who taught the band to play a mere 20 years ago today.

December 2022 sees the 35th anniversary of the first major self-spreading computer virus – the infamous CHRISTMA EXEC worm that temporarily crushed the major mainframe networks of the day…

… not by any deliberately coded side-effects such as file scrambling or data deletion, but simply by leeching too much network bandwidth for its own unauthorised purpose.

As a decoy to disguise the fact that it read in the 1980s IBM equivalents of your email address book (NAMES) and your known-hosts file (NETLOG) in order to find as many new recipients of the malware as possible to send itself to, the malware displayed this:

                *               
                *               
               ***              
              *****             
             *******            
            *********           
          *************                A
             *******            
           ***********                VERY
         ***************        
       *******************           HAPPY
           ***********          
         ***************            CHRISTMAS
       *******************      
     ***********************         AND MY
         ***************        
       *******************         BEST WISHES
     ***********************    
   ***************************     FOR THE NEXT
             ******             
             ******                    YEAR
             ******

If you’re wondering why the virus is widely known as CHRISTMA EXEC, rather than by the full word CHRISTMAS

…that’s because filenames were limited to eight characters, which could be followed by a space and what we would today call an “extension” of EXEC in order to turn them into scripts that could be run directly by the user – executed, in technical jargon.

The virus itself was written in IBM’s powerful text-based scripting language REXX (the resoundingly named Restructured Extended Executor), so a non-programmer looking at the message would probably recognise it as “program code”, and therefore tend to ignore it as unimportant and irrelevant, for all that it might look interesting.

Except that the author of the virus found a cheerful way to embed an instructional lure right into the code itself, which starts with a remark (as in the C language, text between /* and */ in REXX programs is treated as a comment and ignored when the file gets used)…

/*********************/
/*    LET THIS EXEC  */
/*                   */
/*        RUN        */
/*                   */
/*        AND        */
/*                   */
/*       ENJOY       */
/*                   */
/*     YOURSELF!     */
/*********************/

…and then offers the following cheery advice to non-techies:

/*  browsing this file is no fun at all
       just type CHRISTMAS from cms     */

CMS is short for Conversational Monitor System, a command prompt environment on top of IBM’s venerable VM/370 operating system and its many variants, which offered individual users a real-time virtual machine that behaved like a computer all of their own, with its own disk space for storing personal files and programs.

Handily, the user didn’t have to be taught to leave the final -S off the word CHRISTMAS, because CMS would automatically ignore any extra characters and hunt for CHRISTMA EXEC, which was the very script program that the user had just received without expecting it or asking for it.

As stated above, the code did indeed display the Christmas Tree ASCII art – or, more precisely, EBCDIC art, given that IBM famously had its own character encoding system known as Extended Binary Coded Decimal Interchange Code (pronounced ebb-si-dick).

But it also trawled through your NAMES and NETLOG files, which listed other users and computers you regularly contacted, and copied itself to all of them, so that for every user who innocently typed CHRISTMAS at the command prompt…

…a sea of copies of the virus (20? 50? 200?) would be distributed, potentially worldwide, and if any of those recipients (20? 50? 200?) innocently typed CHRISTMAS at the command prompt…

…a sea of copies of the virus would be distributed, and so on, and so on.

Shades of the future

As we said in this week’s podcast, where we discussed this seminal worm:

[This is j]ust like modern macro malware that says to the user, “Hey, macros are disabled, but for your ‘extra safety’ you need to turn them back on… why not click the button? It’s much easier that way.”

35 years ago, malware writers had already figured out that if you ask users nicely to do something that is not at all in their interest, some of them, possibly many of them, will do it.

10 Best Vulnerability Scanning Tools For Penetration Testing

Category: Access Control,Security ToolsDISC @ 10:57 am

A Vulnerability Scanning Tool is one of the essential tools in IT departments Since vulnerabilities pop up every day and thus leaving a loophole for the organization.

The Vulnerability scanning tools help in detecting security loopholes in the application, operating systems, hardware, and network systems.

Hackers are actively looking for these loopholes to use them to their advantage. Vulnerabilities inside a network need to be identified and fixed immediately to leave your attackers at bay.

What does a Vulnerability Scanner do?

Vulnerability scanners are one right way to do this, with their continuous and automated scanning procedures they can scan the network for potential loopholes.

It is on your internet or any device, they would help the IT departments identify the vulnerability and fix it both manually and automatically.

Vulnerability scanning tools do have two different approaches for performing their routines, authenticated and unauthenticated scans.

In the latter case, a penetration tester will show the scan disguised as a hacker without him having trusted access to the corporate network.

What are the Three types of Vulnerability Scanners?

This type of scan will help organizations identify the loopholes which will allow hackers to penetrate the system without trusted permissions.

Following are the types of vulnerability scanners

  • Discovery Scanning
  • Full Scanning
  • Compliance Scanning

What is an example of a Vulnerability Scanner?

The best Web vulnerability scanner in the market should allow you to perform both authenticated and unauthenticated types of scans to nullify network vulnerabilities among other related vulnerability scanners online

Strategies for closing the cybersecurity skills & leadership gap

Category: CISO,Cyber career,vCISODISC @ 11:33 am
arlington-research-nFLmPAf9dVc-unsplash.jpg

As organizations begin to address the risks of an increasingly complex digital landscape, they are recognizing that cybersecurity challenges are compounded by a lack of available talent and skills to mount a necessary defense. The digital skills shortage in the U.S. is at a critical point, highlighting a need for increased investment in workforce training. The Biden White House recently said that roughly 700,000 cyber-defense-related positions nationally are unfilled.

Clearly, CISOs and leaders across the C-suite are focused on the challenge, and many are investing heavily in shoring up gaps in their cybersecurity approach. In an age when a cyberattack can be an existential threat to any organization, cybersecurity engineers will serve as the first responders to such threats.

But organizations are struggling to fill these roles. Cyber professionals face ever-increasing pressure to keep up with more sophisticated and complex threats. The burnout in the profession is significant. What’s more, there hasn’t been a good understanding of the variety of jobs that there are in cybersecurity, and the various skills that can be leveraged for those jobs.

What complicates the effort to fill these roles are the demands placed on them. A strong cybersecurity professional must have advanced skills and experience in the following: meeting the immediate needs of securing the enterprise while also satisfying regulators and compliance officials; keeping a close eye on protections for customers and their personal data; and, if an incident occurs, navigating those interactions and coordinating with law enforcement. These are skills rarely found together.

In fact, not only is there a challenge in filling day-to-day roles within the cybersecurity portfolio, there is also a leadership gap. Many highly skilled cybersecurity professionals avoid taking leadership positions in the field precisely because they do not feel prepared to take on these multivariate tasks.

The solution rests in a two-pronged approach.

#1. Leverage cybersecurity frameworks and automation.

Organizations need to reduce the demand on crisis cyber defense by deploying automated platforms and technologies, such as zero trust security, to screen out threats and examine their entire value chain — including suppliers, vendors and others who may be the source of the greatest potential risks. As part of this effort, trained cybersecurity professionals should be deployed during the software development lifecycle and across business processes so that security and protections can be embedded by design rather than bolted on later.

#2. Migrate cybersecurity to the cloud.

Why the updated ISO 27001 standard matters to every business’ security

Category: Information Security,ISO 27kDISC @ 10:13 am

On the morning of August 4, 2022, Advanced, a supplier for the UK’s National Health Service (NHS), was hit by a major cyberattack. Key services including NHS 111 (the NHS’s 24/7 health helpline) and urgent treatment centers were taken offline, causing widespread disruption. This attack served as a brutal reminder of what can happen without a standardized set of controls in place. To protect themselves, organizations should look to ISO 27001.

ISO 27001 is an internationally recognized Information Security Management System standard. It was first published in 2005 to help businesses implement and maintain a solid information security framework for managing risks such as cyberattacks, data leaks and theft. As of October 25, 2022, it has been updated in several important ways.

The standard is made up of a set of clauses (clauses 4 through 10) that define the management system, and Annex A which defines a set of controls. The clauses include risk management, scope and information security policy, while Annex A’s controls include patch management, antivirus and access control. It’s worth noting that not all of the controls are mandatory; businesses can choose to use those that suit them best.

Why is ISO 27001 being updated?

It’s been nine years since the standard was last updated, and in that time, the technology world has changed in profound ways. New technologies have grown to dominate the industry, and this has certainly left its mark on the cybersecurity landscape. 

With these changes in mind, the standard has been reviewed and revised to reflect the state of cyber- and information security today. We have already seen ISO 27002 (the guidance on applying the Annex A controls) updated. The number of controls has been reduced from 114 to 93, a process that combined several previously existing controls and added 11 new ones.

Many of the new controls were geared to bring the standard in line with modern technology. There is now, for example, a new control for cloud technology. When the controls were first created in 2013, cloud was still emerging. Today, cloud technology is a dominant force across the tech sector. The new controls thus help bring the standard up to date.

In October, ISO 27001 was updated and brought in line with the new version of ISO 27002. Businesses can now achieve compliance with the updated 2022 controls, certifying themselves as meeting this new standard, rather than the now-outdated list from 2013.

How can ISO 27001 certification benefit your business?

Implementing ISO 27001 brings a host of information security advantages that benefit companies from the outset.

Companies that have invested time in achieving ISO 27001 certification will be recognized by their customers as organizations that take information security seriously. Companies that are focused on the needs of their customers should want to address the general feeling of insecurity in their users’ minds.

Moreover, as part of the increasingly rigorous due-diligence processes that many companies are now undertaking, ISO 27001 is becoming mandatory. Therefore, organizations will benefit from taking the initiative early to avoid missing out commercially.

In the case of cyber-defense, prevention is always better than cure. Attacks mean disruption, which almost always proves costly for an organization, in regard to both reputation and finances. Therefore, we might view ISO 27001 as a form of cyber-insurance, where the correct steps are taken preemptively to save organizations money in the long term.

There’s also the matter of education. Often, an organization’s weakest point, and thus the point most often targeted, is the user. Compromised user credentials can lead to data breaches and compromised services. If users were more aware of the nature of the threats they face, the likelihood of their credentials being compromised would decrease significantly. ISO 27001 offers clear and cogent steps to educate users on the risks they face.

Ultimately, whatever causes a business to choose implementation of ISO 27001, the key to getting the most out of it is ingraining its processes and procedures in their everyday activity.

Overcoming the challenge of ISO 27001 certification

A lot of companies have already implemented many controls from ISO 27001, including access control, backup procedures and training. It might seem at first glance that, as a result, they’ve already achieved a higher standard of cybersecurity across their organization. However, what they continue to lack is a comprehensive management system to actually manage the organization’s information security, ensuring that it is aligned with business objectives, tied into a continuous improvement cycle, and part of business-as-usual activities.

While the benefits of ISO 27001 may be obvious to many in the tech industry, overcoming obstacles to certification is far from straightforward. Here are some steps to take to tackle two of the biggest issues that drag on organizations seeking ISO 27001 certification:

  • Resources — time, money, and manpower: Businesses will be asking themselves: How can we find the extra budget and dedicate the finite time of our employees to a project that could last six to nine months? The key here is to place trust in the industry experts within your business. They are the people who will be implementing the standard day-by-day, and they should be placed at the wheel.
  • Lack of in-house knowledge: How can businesses that have no prior experience implementing the standard get it right? In this case, we advise bringing in third-party expertise. External specialists have done this all before: They have already made the mistakes and learned from them, meaning they can come into your organization directly focused on implementing what works. In the long run, getting it right from the outset is a more cost-effective strategy because it will achieve certification in a shorter time.

Next steps toward a successful future

While making this all a reality for your business can seem daunting, with the right plan in place, businesses can rapidly benefit from all that ISO 27001 certification has to offer.

It’s also important to recognize that this October was not the cutoff point for businesses to achieve certification for the new version of the standard. Businesses will have a few months before certification bodies will be ready to offer certification, and there will likely then be a two-year transition period after the new standard’s publication before ISO 27001:2013 is fully retired.

Ultimately, it’s vital to remember that while implementation comes with challenges, ISO 27001 compliance is invaluable for businesses that want to build their reputations as trusted and secure partners in today’s hyper-connected world.

Best practices for implementing a company-wide risk analysis program

Category: Risk Assessment,Security Risk AssessmentDISC @ 11:36 pm

The associated risk management programs are also constantly evolving, and that’s likely due to outside influences such as client contract requirements, board requests and/or specific security incidents that require security teams to rethink and strengthen their strategy. Not surprisingly, CISO’s today face several dilemmas: How do I define the business impact of a cyber event? How much will it cost to protect our company’s most valuable assets? Which investments will make the business most secure? How do we avoid getting sidetracked by the latest cyber breach headline?

A mature risk analysis program can be thought of as a pyramid. Customer-driven framework compliance forms the base (PCI/ISO frameworks required for revenue generation); then incident-driven infrastructure security in the middle (system-focused security based on known common threats and vulnerabilities); with analysis-driven comprehensive coverage at the pinnacle (identification of assets, valuations, and assessment of threat/vulnerability risk).

risk analysis

How do you kickstart that program? Here are five steps that I’ve found effective for getting risk analysis off the ground.

Determine enterprise-specific assets

The first step is determining what is critical to protect. Unlike accounting assets (e.g., servers, laptops, etc.), in cybersecurity terms this would include things that are typically of broader business value. Often the quickest path is to talk with the leads for different departments. You need to understand what data is critical to the functioning of each group, what information they hold that would be valuable to competitors (pricing, customers, etc.) and what information disclosures would hurt customer relationships (contract data, for instance).

Also assess whether each department handles trade secrets, or holds patents, trademarks, and copyrights. Finally, assess who handles personally identifiable information (PII) and whether the group and its data are subject to regulatory requirements such as GDPR, PCI DSS, CCPA, Sarbanes Oxley, etc.

When making these assessments, keep three factors in mind: what needs to be safe and can’t be stolen, what must remain accessible for continued function of a given department or the organization, and what data/information must be reliable (i.e., that which can’t be altered without your knowledge) for people to do their jobs.

Value the assets

Once you’ve identified these assets, the next step is to attach a value. Again, I make three recommendations: keep it simple, make (informed) assumptions, and err on the side of overestimating. The reason for these recommendations is that completing a full asset valuation for an enterprise would take years and wouldn’t ever be finished (because assets constantly change).

Efficient risk analysis requires a more practical approach that uses broad categories, which can then be prioritized to understand where deeper analysis is needed. For instance, you might use the following categories, and assign values based on informed assumptions:

  • Competitive advantage – the items/processes/data that are unique to your company and based on experience. These are items that would be of value to a competitor to build on. To determine value, consider the cost of growing a legitimate competitor in your dominant market from scratch, including technology and overhead.
  • Client relationships – what directly impacts customer relationships, and therefore revenue. This includes “availability” impacts from outages, SLAs, etc. Value determination will likely be your annual EBIT goal, and impact could be adjusted by a Single Loss Exposure.
  • Third-party partnerships – relating to your ability to initiate, maintain or grow partner networks, such as contractors, ISPs or other providers. When valuing, consider the employee labor cost needed to recruit and maintain those partners.
  • Financial performance – items that impact your company’s ability to achieve financial goals. Again, valuation might equate to annual EBIT.
  • Employee relations – the assets that impact your ability to recruit and retain employees. Valuation should consider the volume of potential losses and associated backfill needs, including base salaries, bonuses, benefit equivalencies, etc.

Determine relevant threats, assess vulnerability, and identify exposures

When it comes to analyzing risk from threats, vulnerabilities and exposures, start with the common security triad model for information security. The three pillars – Confidentiality, Integrity and Availability (CIA) – help guide and focus security teams as they assess the different ways to address each concern.

Confidentiality touches on data security and privacy; it entails not only keeping data safe, but also making sure only those who need access, have it.

Integrity reflects the need to make sure data is trustworthy and tamper-free. While data accuracy can be compromised by simple mistakes, what the security team is more concerned with is intentional compromise that’s designed to harm the organization.

Availability is just what it sounds like – making sure that information can be accessed where and when needed. Availability is an aspect of the triad where security teams need to coordinate closely with IT on backup, redundancy, failover, etc. That said, it also involves everything from secure remote access to timely patches and updates to preventing acts of sabotage like denial of service or ransomware attacks.

In undertaking this part of the risk assessment, you’re using this security triad to determine threats, and then identifying exposure and assessing vulnerability to better estimate both the potential impact and probability of occurrence. Once these determinations are made, you’re ready for the next step.

Define risk

AV = assigned Asset Value (quantitative/qualitative) as identified above.
EF = the Exposure Factor, a subjective assessment of the potential percentage loss to the asset if a specific threat is realized. For example, an asset may be degraded by half, giving an EF of 0.50.

From this we can calculate the Single Loss Expectancy (SLE) – the monetary value from one-time risk to an asset – by multiplying AV and EF. As an example, if the asset value is $1M, and the exposure factor from a threat is a 50% loss (0.50) then the SLE will be $500,000.

Risk definition also takes this one step further by using this SLE and multiplying it by a potential Annualized Rate of Occurrence (ARO) to come up with the Annualized Loss Expectancy (ALE). This helps us understand the potential risk over time.

When working through these figures, it’s important to recognize that potential loss and probability of occurrence are hard to define, and thus the potential for error is high. That’s why I encourage keeping it simple and overestimating when valuing assets – the goal is to broadly assess the likelihood and impact of risk so that we can better focus resources, not to get the equations themselves perfectly accurate.

Implement and monitor safeguards (controls)

Now that we have a better handle on the organizational risks, the final steps are more familiar territory for many security teams: implementing and monitoring the necessary and appropriate controls.

You’re likely already very familiar with these controls. They are the countermeasures – policies, procedures, plans, devices, etc. – to mitigate risk.

Controls fall into three categories: preventative (before an event), detective (during) and corrective (after). The goal is to try to stop an event before it happens, quickly react once it does, and efficiently get the organization back on its feet afterward.

Implementing and monitoring controls are where the rubber hits the road from a security standpoint. And that’s the whole point of the risk analysis, so that security professionals can best focus efforts where and how appropriate to mitigate overall organizational risk.

What is an Identity Verification Service and How Does it Work?

Category: Identity TheftDISC @ 10:57 am

In an increasingly technologically-based world, being certain of precisely who you are speaking to or doing business with can be tricky. Identity verification is an important step in most online transactions that concern money or sensitive information and services, but it can also be used during recruitment processes as a part of a background check. 

This article will explain what an identity verification service is, why they are useful, and how they work.

What is an Identity Verification Service?

An identity verification service is a process by which the information and identity provided by an individual is investigated and found to be true or false. These comprehensive online services are based on the traditional identity verification processes used in banks and other financial institutions when new accounts are opened. 

Technological services are more robust and comprehensive in their verification methods, however. The point of this process is to check and verify that the person applying for an account or service is being honest and upfront about who they are.

Why Use an Identity Verification Service?

While you can find arrest history with a universal background check (as well as other crucial information), the ability to complete a background check of any kind requires correct information about an individual.

Using an identity verification service enables you to confirm that you are performing a background check on, or providing a service to, a person who is identifying themselves correctly. This ensures that the information you receive from a check is correct and connected to the person you are dealing with.

There are other reasons to use such a service, however. For example, if you run a business with an online component identity verification at login, it’s important for data protection purposes. 

Identity verification is also an important part of risk management for most businesses and can help you to avoid fines and legal issues, reduce the risk of fraud, and help you to meet regulatory requirements while showing due diligence.

How Do Identity Verification Services Work?

Digital identity verification services collect and verify personal data and information, usually at the point of account access or onboarding to a new service, by checking it against reputable sources. There are different approaches to this process:

  • Data-oriented digital verification
  • Traditional, document-based digital identity verification

In most cases, data-based identity verification is sufficient, especially for platforms such as online shopping or online lottery ticket purchases. In these cases, the service provider or business may request information such as your date of birth, full name, or national ID/social security number. 

What is an Identity Verification Service and How Does it Work?

For financial services, such as banking or personal loan applications, however, digital document-based verification is usually required. In these cases, the institution or business you are dealing with may request copies or pictures of official documents, such as your driver’s license or birth certificate.

Whichever method of identity verification a company or institution undertakes, the process of verification is the same. The documents or data provided will be checked against trusted sources to ensure that all details match perfectly. When there are no issues, this is a very quick process that should take no more than a few minutes.

What Happens When An Identity Check Fails?

So, what happens when the identity verification process fails? What are the secondary processes, and what are the repercussions when information is found to be false? There are a number of potential issues that can cause queries or failures in the identity verification process. The most common are:

  • Typos or spelling errors.
  • Out-of-date documentation.
  • Obscured or damaged documentation.
  • Poor image quality regarding documentation.

In most cases, the first reaction of a company will be to query the details that do not match or request that documentation be re-sent. If all is in order, they may proceed to a positive verification, but it is also common for companies to ask for secondary or supporting information or documents in these cases.

If issues cannot be resolved and it is impossible to verify the identity of a person, there are two possibilities. Firstly, and in most cases, services will be denied to the applicant on the basis of failed identity verification.

In some cases, however, more robust action may be taken. For example, trying to open a bank account under a false name is a legal offense and financial institutions may see fit to hand information over to the authorities.

Nearly 500 million WhatsApp User Records Sold Online

Category: Dark Web,Hacking,Social networkDISC @ 10:06 am

The 2022 database is said to contain WhatsApp user data from 84 countries with Egypt having the largest chunk of stolen phone numbers.

In what is becoming a rather common trend, a threat actor is claiming to sell 487 million WhatsApp users’ mobile phone numbers on a popular hacking community forum which surfaced as an alternative to popular and now-sized Raidforums.

The 2022 database is said to contain WhatsApp user data from 84 countries with Egypt having the largest chunk of stolen phone numbers (45 million), Italy with 35 million, and the US with 32 million. 

The complete list of countries is included in the original report by Cybernews which also contains the exact amount of numbers up for sale. According to the threat actor, they are willing to sell the US dataset for $7000, the UK one for $2500, and the German one for $2000. 

Nearly 500 million WhatsApp User Records Sold Online

Upon being requested, the threat actor also shared a sample of data with researchers who then confirmed that the numbers included in the sample were in fact WhatsApp users. The exact sample contained 1097 UK and 817 US mobile numbers. 

The seller did not reveal their process for obtaining the database and simply said they “used their strategy” to collect the data. Whatever the method used, the damage that can be caused by this leakage should not be taken lightly.

Such data is readily bought by attackers to use for smishing and vishing attacks. It is advised that you cautiously interact with unknown calls, unsolicited calls, and messages. Impersonation and fraud are also common worries associated with mobile number leakage. 

Meta has refused to comment on this for now, while in their report, Cybernews speculates that this information could have been obtained by harvesting information at scale, also known as scraping, which violates WhatsApp’s Terms of Service. 

However, Hackread.com can confirm that, at the time of writing, the listing was deleted from the hacker forum. Another listing was published in which another threat actor is claiming to sell details of WhatsApp users.
