GitKraken flaw lead to the generation of weak SSH keys

The development team behind the Git GUI client GitKraken has fixed a vulnerability that was leading to the generation of weak SSH keys. The developers addressed the flaw with the release of version 8.0.1.

The issue resides in the open-source library used by the Git GUI client to generate SSH keys, all the keys generated using versions 7.6.x, 7.7.x, and 8.0.0 of GitKraken are potentially affected.

The latest version of the Git GUI client (version 8.0.1) uses a new SSH key generation library.

“This issue only affects GitKraken users who generated SSH keys through the GitKraken interface using versions 7.6.x, 7.7.x,  8.0.0. If you are not sure what version you used to generate your SSH key, we encourage you to renew your key through the following process.” reads the advisory.

“Affected users need to:

  1. Remove all old generated SSH keys stored locally. 

  2. Generate new SSH keys using GitKraken 8.0.1, or later, for each of your Git service providers.“

The development team already notified the Git hosting service providers GitHub, Bitbucket, GitLab, and Azure DevOps, they also revoked the weak public keys used.

The development team is not aware of any accounts being compromised due to this weakness.

Apache patch proves patchy – now you need to patch the patch

Apache patch proves patchy – now you need to patch the patch

Software patches are sometimes a bit like buses.

You don’t get one for a while, and then three come at once.

For buses on busy urban routes, at least, the explanation of the phenomenon goes something like this.

If three buses start out travelling the same route together in a nicely spaced sequence, then the first one is most likely to be the slowest, because it will be stopping to scoop up most of the waiting passengers, while the ones behind will tend to travel faster because they need to stop less often or for shorter periods.

So buses naturally tend to scrunch up and arrive in bursts.

Burst-mode software patches

When it comes to software patches, however, the problem often works the other way around.

If the first patch arrives too quickly, then it may not have been reviewed or tested quite as much as you might like.

So it’s not so much that the next patch in the queue catches up because the first one is too slow, but that the next one has to be completed in a rush to keep up…

…and, if you aren’t careful, then that second patch might itself beget a third patch, needed to patch the patch that patched the first patch.

Three Apache buses

And thus with Apache: just two days ago, we reported a path validation bug dubbed CVE-2021-41773 that was introduced in Apache 2.4.49:

Apache web server zero-day bug is easy to exploit – patch now!

We advised you to update to 2.4.50, which would indeed have protected you against at least some of the known exploits already circulating on Twitter.

PoC exploit for 2 flaws in Dahua cameras leaked online

A proof of concept exploit for two authentication bypass vulnerabilities in Dahua cameras is available online, users are recommended to immediately apply updates.

Experts warn of the availability of proof of concept (PoC) exploit code for a couple of authentication bypass vulnerabilities in Dahua cameras, tracked as CVE-2021-33044 and CVE-2021-33045. 

A remote attacker can exploit both vulnerabilities by sending specially crafted data packets to the vulnerable cameras.

“The identity authentication bypass vulnerability found in some Dahua products during the login process. Attackers can bypass device identity authentication by constructing malicious data packets.” reads the advisory published by the vendor in early September.

dahua

The flaw received a CVSS v3 score of 8.1, the vendor recommended its customers to install security updates.

The list of affected models is very long, it includes IPC-X3XXX,HX5XXX, HUM7XX, VTO75X95X, VTO65XXX, VTH542XH, PTZ Dome Camera SD1A1, SD22, SD49, SD50, SD52C, SD6AL, Thermal TPC-BF1241, TPC-BF2221, TPC-SD2221, TPC-BF5XXX, TPC-SD8X21, TPC-PT8X21B, NVR1XXX, NVR2XXX, NVR4XXX, NVR5XXX, NVR6XX.

It could be quite easy for threat actors in the wild to find exposed Dahua devices using a search engine like Shodan and attempt to hack them using the available PoC code. In order to protect Dahua devices, users have to install the latest firmware version.

Divide Between Security, Developers Deepens

Divide Between Security, Developers Deepens

Security professionals work hard to plan secure IT environments for organizations, but the developers who are tasked with implementing and carrying these plans and procedures are often left out of security planning processes, creating a fractured relationship between development and security.

This was the conclusion from a VMware and Forrester study of 1,475 IT and security managers, including CIOs and CISOs and managers with responsibility for security strategy and decision-making.

The report found security is still perceived as a barrier in organizations, with 52% of developer respondents saying they believed that security policies are stifling their ability to drive innovation.

Only one in five (22%) developers surveyed said they strongly agree that they understand which security policies they are expected to comply with and more than a quarter (27%) of the developers surveyed are not involved at all in security policy decisions, despite many of these decisions greatly impacting their roles.

The research indicated that security needs a perception shift and should be more deeply embedded across people, processes and technologies.

This means involving developers in security planning earlier and more often; learning to speak the language of the development team rather than asking development to speak security, sharing KPIs and increasing communication to improve relationships and automating security to improve scalability, the report recommended.

Set a Clear Scope for Security Requirements

“Regardless of whether if it’s customer-facing functionality or a business logic concern, every line of code developed should prioritize security as a design feature,” he said. “Once security is taken as seriously as other drivers for DevOps adoption, then a fully holistic integration can be achieved.”

Arizona governor announces the launch of Command Center to protect state computer systems

The governor of Arizona, Doug Ducey, has announced the launch of a Cyber Command Center to address the thousands of attacks that daily target government computers.

The governor of Arizona, Doug Ducey, has launched a Cyber Command Center to repel the huge amount of attacks that every day hit the computer systems of the state.

The move is the response of the Arizona administration to hundreds of thousands of cyberattacks that hit the state.

At a ceremony Monday at the Department of Public Safety’s Arizona Counter Terrorism Information Center in Phoenix, Ducey explained that Cyber Command Center has been established to protect the IT infrastructure of the state.

“The Cyber Command Center brings four state public safety agencies together in one room with one mission: Guard the state’s computers against attacks and by extension, help protect the over 7 million residents of the Grand Canyon State.” reads a post published by AZCentral.

“When we protect your data, we protect you at home as well,” Arizona Department of Homeland Security Director Tim Roemer said in an interview. “We help you not fall victim to identity theft, for example. Because once your data is compromised, they use that to open up accounts.”

In the case of a severe cyber attack, experts at the center will coordinate the incident response activities.

Baby died at Alabama Springhill Medical Center due to cyber attack

A baby allegedly received inadequate childbirth health care, and later died, at an Alabama Springhill Medical Center due to a ransomware attack.

An Alabama woman named Teiranni Kidd has filed suit after the death of her baby, she claims that the Springhill Medical Center was not able to respond to a cyberattack that crippled its systems causing the death of the infant daughter, reported The Wall Street Journal.

According to Kidd, the Alabama hospital did not disclose that it was hit by a severe cyberattack that interfered with the care for her baby, Nicko Silar.

“Nicko suffered a severe brain injury when medical staff failed to notice the umbilical cord was wrapped around her neck because of a “lack of access to critical services and information caused by the cyberattack,” the suit said. She died nine months after the cord cut off her blood and oxygen supply.” reported The New York Post.

Gift card fraud: four suspects hit with money laundering charges

Gift card fraud: four suspects hit with money laundering charges

You might be forgiven for thinking that cybercrime is almost all about ransomware and cryptocoins these days.

In a ransomware attack, the crooks typically blackmail you to send them cryptocurrency in return for giving you your stolen data back (or for not selling it on to someone else).

In a cryptocoin attack, the crooks typically take your cryptocurrency for themselves, perhaps by exploiting a bug in the trading software you use, or by stealing your private keys so they have direct access to your cryptocurrency wallet.

This sort of criminality sometimes involves amounts reaching tens of millions of dollars, or even hundreds of millions of dollars, in a single attack.

But gift card fraud still fills a distressing niche in the cybercrime ecosystem, where a gang of crooks redeem gift cards that you paid for, either because you were convinced that those cards were earmarked for something else, or because the crooks got temporary access to one of your online accounts that allowed them to buy gift cards on your dime.

Indeed, the US Department of Justice announced this week the indictment of four suspected gift card scammers, and alleges that that these four had ended up with more than 5000 fraudulently obtained cards to spend on themselves.

This sort of crime might not reach the stratospheric financial territory of ransomware criminals, or the truly cosmic amounts seen in cryptocurrency attacks…

…but if we reasonably assume an average of $200 a gift card (we know that in many scams, crooks come away with more than that on each card), we’re still looking at $1,000,000 of ill-gotten gains in this court case alone.

CISA releases Insider Risk Mitigation Self-Assessment Tool

The US CISA has released a new tool that allows to assess the level of exposure of organizations to insider threats and devise their own defense plans against such risks.

The US Cybersecurity and Infrastructure Security Agency (CISA) has released the Insider Risk Mitigation Self-Assessment Tool, a new tool that allows organizations to assess their level of exposure to insider threats.

Insider threats pose a severe risk to organizations, the attacks are carried out by current or former employees, contractors, or others with inside knowledge, for this reason they are not easy to detect.

An attack from insiders could compromise sensitive information, cause economic losses, damages the reputation of the organization, theft of intellectual property, reduction of market share, and even physical harm to people. 

The tool elaborates the answers of the organizations to a survey about their implementations of a risk program management for insider threats.

“The Cybersecurity and Infrastructure Security Agency (CISA) released an Insider Risk Mitigation Self-Assessment Tool today, which assists public and private sector organizations in assessing their vulnerability to an insider threat.  By answering a series of questions, users receive feedback they can use to gauge their risk posture.  The tool will also help users further understand the nature of insider threats and take steps to create their own prevention and mitigation programs.” reads the announcement published by CISA.

New APT ChamelGang Targets Russian Energy, Aviation Orgs

Category: APT,Information Security — DISC @ 9:23 am

First appearing in March, the group has been leveraging ProxyShell against targets in 10 countries and employs a variety of malware to steal data from compromised networks.

A new APT group has emerged that’s specifically targeting the fuel and energy complex and aviation industry in Russia, exploiting known vulnerabilities like Microsoft Exchange Server’s ProxyShell and leveraging both new and existing malware to compromise networks.

Researchers at security firm Positive Technologies have been tracking the group, dubbed ChamelGang for its chameleon-like capabilities, since March. Though attackers mainly have been seen targeting Russian organizations, they have attacked targets in 10 countries so far, researchers said in a report by company researchers Aleksandr Grigorian, Daniil Koloskov, Denis Kuvshinov and Stanislav Rakovsky published online Thursday.

To avoid detection, ChamelGang hides its malware and network infrastructure under legitimate services of established companies like Microsoft, TrendMicro, McAfee, IBM and Google in a couple of unique ways, researchers observed.

Supply Chain Emerging as Cloud Security Threat

Category: Cloud computing,Cyber Threats — DISC @ 9:20 am
Supply Chain Emerging as Cloud Security Threat

Misconfigurations in software development environments and poor security hygiene in the supply chain can impact cloud infrastructure and offer opportunities for malicious actors to control unwitting victims’ software development processes.

These were the results of a report from Palo Alto Networks’ security specialist Unit 42, which conducted a red team exercise with a large SaaS provider.

Within three days, the company discovered critical software development flaws that could have exposed the organization to an attack similar to those perpetrated against SolarWinds and Kaseya.

If an attacker (like an APT) compromises third-party developers, it’s possible to infiltrate thousands of organizations’ cloud infrastructures, the report warned.

Supply Chain Flaws in the Cloud

Matt Chiodi, CSO of public cloud at Palo Alto Networks, explained that supply chain flaws in the cloud are difficult to detect because of the massive number of building blocks that go into even a basic cloud-native application.

“Our researchers estimated that the typical cloud-native application is built upon hundreds of these packages,” he said. “Let’s call them ‘Legos.’ Each of these Legos that developers plug into their application carries a certain risk and can be a vector to another supply chain attack.”

The report highlights how vulnerabilities and misconfigurations can quickly snowball within the context of the cloud software supply chain, and called for organizations to “shift security left.”

“Shifting security left is about moving security as close to development as possible,” said Chiodi. “Historically, security and development teams have operated independently of each other.” He added that development teams like to move quickly and try new things and security is more often the opposite.

“The concept of ‘shift left’ attempts to not change developer behaviors, but rather equip them with processes and tools that work natively to secure their existing methods of developing software,” Chiodi said. “If security teams can equip development teams with processes and tools that work natively with development tools and measure regularly, they greatly reduce their risks of supply chain insecurity from cloud-native applications. This is a good first step.”

He pointed out the first wave of migrations to the cloud was marked by “lift and shift,” meaning that organizations simply took existing applications as-is and moved them to the cloud.

“When they did this, they could say the applications were running in the cloud, but the applications themselves were not cloud-native,” he said.

Apple Pay with Visa Hacked to Make Payments via Unlocked iPhones

Category: Information Security,Mobile Security — DISC @ 9:08 am

Researchers have demonstrated that someone could use a stolen, unlocked iPhone to pay for thousands of dollars of goods or services, no authentication needed.

An attacker who steals a locked iPhone can use a stored Visa card to make contactless payments worth up to thousands of dollars without unlocking the phone, researchers are warning.

The problem is due to unpatched vulnerabilities in both the Apple Pay and Visa systems, according to an academic team from the Universities of Birmingham and Surrey, backed by the U.K.’s National Cyber Security Centre (NCSC). But Visa, for its part, said that Apple Pay payments are secure and that any real-world attacks would be difficult to carry out.

The team explained that fraudulent tap-and-go payments at card readers can be made using any iPhone that has a Visa card set up in “Express Transit” mode. Express Transit allows commuters around the world, including those riding the New York City subway, the Chicago El and the London Underground, to tap their phones on a reader to pay their fares without unlocking their devices.

“An attacker only needs a stolen, powered-on iPhone,” according to a writeup (PDF) published this week. “The transactions could also be relayed from an iPhone inside someone’s bag, without their knowledge. The attacker needs no assistance from the merchant.”

In a proof-of-concept video, the researchers showed a £1,000 payment being sent from a locked iPhone to a standard, non-transit Europay, Mastercard and Visa (EMV) credit-card reader.

Exploiting Apple Pay Express Transit Mode

The attack is an active man-in-the-middle replay and relay attack, according to the paper. It requires an iPhone to have a Visa card (credit or debit) set up as a transit card in Apple Pay.

The attackers would need to set up a terminal that emulates a legitimate ticket barrier for transit. This can be done using a cheap, commercially available piece of radio equipment, researchers said. This tricks the iPhone into believing it’s connecting to a legitimate Express Transit option, and so, therefore, it doesn’t need to be unlocked.

“If a non-standard sequence of bytes (Magic Bytes) precedes the standard ISO 14443-A WakeUp command, Apple Pay will consider this [to be] a transaction with a transport EMV reader,” the team explained.

Expert discloses new iPhone lock screen vulnerability in iOS 15

The security researcher Jose Rodriguez discovered a new lock screen vulnerability for iOS 15 (& iOS 14.8) that has yet to be fixed.

The security researcher Jose Rodriguez (@VBarraquito) discovered a new lock screen vulnerability for iOS 15 (& iOS 14.8) that has yet to be addressed by Apple. A threat actor with physical access to a vulnerable device can access Notes via Siri/Voice Over.

Rodriguez explained that in real incidents, unattended or stolen devices with a lock screen bypass vulnerability are exposed to attacks that could leverage a lock screen vulnerability to access sensitive information.

This specific type of vulnerability represents a serious threat to individuals and organizations, for this reason, the expert suggests including their research when conducting a mobile pen-testing assessment.

The expert disclosed details about the lock screen bypass vulnerability after Apple downplayed similar flaws, tracked as CVE-2021-1835 and CVE-2021-30699, reported by the researcher earlier this year.

The flaws allowed an attacker to access instant messaging apps like WhatsApp or Telegram even while the mobile device was locked.

Rodriguez explained that Apple partially fixed the issue and did not involve him in the test of the released patch.

Then the expert proposed a variant of the same bypass issue that leverages Apple Siri and VoiceOver services to access the Notes app.

The expert also published a video PoC for the latest screen bypass vulnerability:

Let me suggest reading a post published by the expert that includes a long list of similar vulnerabilities:

How to Mitigate the Top 4 Ransomware Vectors

The ransomware economy is booming. Ransomware gangs are so successful that if cybercriminals were companies, some would be considered “unicorns.” Organized crime syndicates have taken over this highly lucrative extortion racket and are now running the ransomware economy at an industrial scale. The U.S. is reportedly hit by seven ransomware attacks every hour, with ransomware demands expected to hit $20 billion this year and $265 billion in ten years.

Top Infection Vectors of a Ransomware Attack

Cybercriminals need a delivery system that drops the ransomware payload on the target machine. Once this malware infiltrates your network, it takes over and can perform several damaging actions such as file encryption, credential hijacking, data exfiltration and even deletion or corruption of your backups. Recognizing and fortifying defenses against such infection vectors is key for a proactive ransomware defense. Cybercriminals continue to evolve their vectors in line to changes in internet and technology however, here are the top four infection vectors:

Port of Houston was hit by an alleged state-sponsored attack

One of the major US ports, the Port of Houston, revealed that it was hit by a cyber attack in August that had no impact on its systems.

“The Port of Houston Authority (Port Houston) successfully defended itself against a cybersecurity attack in August. Port Houston followed its Facilities Security Plan in doing so, as guided under the Maritime Transportation Security Act (MTSA), and no operational data or systems were impacted as a result.” reads a statement issued on Thursday by Port officials.

Cybersecurity and Infrastructure Security Agency Director Jen Easterly disclosed the attack at a Senate committee hearing Thursday morning. She believed the attack was conducted by a “nation-state actor” that exploited a zero-day flaw in a Zoho user authentication device.

“We are working very closely with our interagency partners and the intelligence community to better understand this threat actor so that we can ensure that we are not only able to protect systems, but ultimately to be able to hold these actors accountable,” Easterly added.
