New Vulnerability Could Put IoT Devices at Risk

Category: IoT SecurityDISC @ 11:36 am

A new vulnerability targets Thales, a leading maker of IoT components. Learn how the X-Force Red team identified the security flaw and best practices for addressing the risk.

Society relies so heavily on technology that the number of internet connected devices used globally is predicted to grow to 55.9 billion by 2025. Many of these devices span parts of Industrial Control Systems (ICS) that impact the physical world, assist us in our daily lives at home and monitor and automate everything from energy usage to machine maintenance at work. The potential to abuse these systems has already caught the eye of cybercriminals; according to the 2020 IBM X-Force Threat Intelligence Index, attacks against these systems increased over 2000% since 2018.

As part of their ongoing research, IBM’s team of hackers, X-Force Red, have discovered a new IoT vulnerability that can be exploited remotely. The manufacturer, Thales, has made a patch available for CVE-2020-15858 to customers since February 2020 and X-Force Red has been working together to ensure users are aware of the patch and taking steps to secure their systems.

Of the billions of smart devices in use today, Thales is one of leading makers of components that enable them to connect to the internet, securely store information and verify identities. Thales’ entire portfolio connects more than 3 billion things every year and more than 30,000 organizations rely on its solutions for everything from smart energy meters to medical monitoring devices and cars.

PoC exploit code for two Apache Struts 2 flaws available online

Category: Security vulnerabilitiesDISC @ 11:37 am

Security researchers have discovered a PoC code and exploit available online that can be used to trigger unpatched security flaws in Apache Struts 2.

Security researchers have discovered a PoC code and exploit available on GitHub that that can be used to trigger the security vulnerabilities in Apache Struts 2.

The Proof-of-concept exploit code was released last week, it allows to trigger the CVE-2019-0230 and CVE-2019-0233 vulnerabilities in Apache Struts 2 that are classified as remote code-execution and denial-of-service issues respectively. Both vulnerabilities were addressed by the Apache team in November 2019.

According to an advisory published by the Cybersecurity and Infrastructure Security Agency (CISA) the two flaws impact Apache Struts versions 2.0.0 through 2.5.20. The Apache Struts Security Team urges administrators to upgrade their installs to Struts 2.5.22.

Apache Struts 2 is an open-source, extensible framework for creating enterprise-ready Java web applications.

Unpatched installs could allow attackers to carry out malicious activities. In 2017, the credit reporting agency Equifax suffered a massive data breach, attackers exploited the CVE-2017-5638 Apache Struts vulnerability.

The CVE-2019-0230, for which a PoC exploit code is available only, could be triggered when a threat actor sends a malicious Object-Graph Navigation Language (OGNL) expression that can result in a remote code-execution in the context of the affected application.

Depending on the privileges associated with the affected application, an attacker could perform multiple malicious activities, such as install applications; modify or delete data, or create new admin accounts.

The DoS flaw, tracked as CVE-2019-0233, affects the write permissions of file directories that could lead to conditions ripe for a DoS attack.

According to the Apache Struts Wiki description of the bug, this flaw can be triggered with a file upload to a Strut’s Action that exposes the file.

“When a file upload is performed to an Action that exposes the file with a getter, an attacker may manipulate the request such that the working copy of the uploaded file is set to read-only. As a result, subsequent actions on the file will fail with an error.” reads the advisory. “It might also be possible to set the Servlet container’s temp directory to read only, such that subsequent upload actions will fail,”

The Apache security bulletin recommends to upgrade outdated installs and verify no unauthorized system modifications have occurred on the system.

CISA alerts of phishing attack targeting SBA loan relief accounts

Category: PhishingDISC @ 9:31 am

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday released an alert about phishing attacks targeting various government organizations to steal logins for the Small Business Administration COVID-19 loan relief accounts.

In a newer phishing attack that started in August, security researchers saw the threat actor using convincing tricks to fool potential victims into providing personal and financial information

 

Some Countermeasures:

Checking the source of the message for the sender address will reveal the real one. Simply comparing it with the legitimate email will show the fraud attempt.

Paying attention to the URL in the address bar should also ensure that you don’t fall for a trick and are on the genuine page.

CISA recommends organizations include warning banners for messages from an external source. Even if the message bypasses email defenses, users may act with more caution.

Bracing for election day, Facebook rolls out voting resources to US users

Category: Election SecurityDISC @ 10:57 am

Eager to avoid a repeat of its disastrous role as a super-spreader of misinformation during the 2016 election cycle, Facebook is getting its ducks in a row. Following an announcement earlier this summer, the company is now launching a voting information hub that will centralize election resources for U.S. users and ideally inoculate at least […]

The voting information center will appear in the menu on both Facebook and Instagram. As part of the same effort, Facebook will also target U.S. users with notifications based on location and age, displaying relevant information about voting in their state. The info center will help users check their state-specific vote-by-mail options, request mail-in ballots and provide voting-related deadlines.

Along with other facets of its pre-election push, Facebook will roll previously-announced “voting alerts,” a feature that will allow state election officials to communicate election-related updates to users through the platform. “This will be increasingly critical as we get closer to the election, with potential late-breaking changes to the voting process that could impact voters,”

If you haven’t yet patched this critical hole in SAP NetWeaver Application Server, today is not your day

Category: Security vulnerabilitiesDISC @ 1:32 pm

Full details of security vuln plus proof-of-concept exploits revealed

This critical-severity bug – scoring 9.9 out of 10 on the CVSS v3 meter – can be exploited by a rogue authenticated user, or someone whose access has been hijacked, to inject arbitrary code into an application server. This means they can run malicious commands they shouldn’t be able to on the server, download sensitive information, or crash the installation.

“In consequence, an attacker can break out of the desired syntactic instructions. Injecting ABAP code in the VALUE field allows the attacker to manipulate the source code of the generated subroutine pool and thereby the execution logic of the entire module. Since the attacker can freely choose the characters that can be used in this field, arbitrary ABAP code can be injected.

“To exploit this behavior an attacker can supply special characters like ‘ and . to escape the string quotation that is built into the source code. Afterwards, an attacker can simply specify any semantically valid ABAP code that gets executed by the application server.”

WSJ News Exclusive | TikTok Tracked User Data Using Tactic Banned by Google

Category: Cyber surveillance,Information PrivacyDISC @ 3:16 pm

TikTok skirted a privacy safeguard in Google’s Android operating system to collect unique identifiers from millions of mobile devices, data that allows the app to track users online without allowing them to opt out, a Wall Street Journal analysis has found.

The tactic, which experts in mobile-phone security said was concealed through an unusual added layer of encryption, appears to have violated Google policies limiting how apps track people and wasn’t disclosed to TikTok users. TikTok ended the practice in November, the Journal’s testing showed.

The identifiers collected by TikTok, called MAC addresses, are most commonly used for advertising purposes. The White House has said it is worried that users’ data could be obtained by the Chinese government and used to build detailed dossiers on individuals for blackmail or espionage.

Twitter stepped up search to fill top security job ahead of hack

Search for a chief information security officer

Twitter Inc had stepped up its search for a chief information security officer in recent weeks, two people familiar with the effort told Reuters, before the breach of high-profile accounts on Wednesday raised alarms about the platform’s security. Twitter said hackers had targeted employees with access to its internal systems and “used this access to take control of many highly-visible (including verified) accounts.”

The second and third rounds of hijacked accounts tweeted out messages telling users to send bitcoin to a given address in order to get more back. Publicly available blockchain records show the apparent scammers received more than $100,000 worth of cryptocurrency.

The U.S. House Intelligence Committee was in touch with Twitter regarding the hack, according to a committee official who did not wish to be named.

Apple strong-arms entire CA industry into one-year certificate lifespans

Category: cyber securityDISC @ 11:18 pm

Apple, Google, and Mozilla reduce the lifespan for HTTPS certificates to 398 days, against the wishes of Certificate Authorities. A decision that Apple unilaterally took in February 2020 has reverberated across the browser landscape and has effectively strong-armed the Certificate Authority industry into bitterly accepting a new default lifespan of 398 days for TLS certificates.

Following Apple’s initial announcement, Mozilla and Google have stated similar intentions to implement the same rule in their browsers.

Starting with September 1, 2020, browsers and devices from Apple, Google, and Mozilla will show errors for new TLS certificates that have a lifespan greater than 398 days.

Digital Downfall: Technology, Cyberattacks and the End of the American Republic

Category: Cyber Attack,HackingDISC @ 1:34 pm

Digital Downfall: Technology, Cyberattacks and the End of the American Republic…

Source: Digital Downfall: Technology, Cyberattacks and the End of the American Republic:

Is America on the brink of civil war?

Could foreign cyber plots turn Americans against one another and cause a disastrous domestic conflict?

What would happen if the lights went out and the technology we rely upon to run American life is no longer available?

The present dangers are real. The US is more vulnerable to destructive foreign interference today than it has been in over a century. As Russia and China realize they can’t win shooting wars against the US, they have devised new and cunning ways to destabilize American politics and cripple the US economy. Cyber meddling in elections, disinformation campaigns, abuse of social media to widen racial and political divides, and the theft of military data are just some of the malicious acts threatening the Republic. Digital Downfall examines the potential effects of such attacks, with a look at:

  • The vulnerability of the US to cyber attack
  • American technological weaknesses that could be exploited by our enemies
  • How the US military could be affected by cyberwar
  • The possibility that the American Republic we know could be destroyed
  • America’s relationship with racism
  • What the future may hold

And more…The dangers posed by external sources can only be real when the internal politics of the United States is in a fragile state. The past four years bear testimony to this political decline as does every passing day of the Trump presidency.The perfect storm of external interference, a rampant and deadly pandemic, and a culture of racism that will no longer be tolerated is upon us.Who knows where it will lead to, or what will be left at the end.
