Microsoft has discovered several vulnerabilities, collectively referred to as Nimbuspwn, to gain root privileges on Linux systems

 Microsoft has discovered several vulnerabilities, collectively referred to as Nimbuspwn, that could allow an attacker to elevate privileges to root on many Linux desktop endpoints. The vulnerabilities can be chained together to gain root privileges on Linux systems, allowing attackers to deploy payloads, like a root backdoor, and perform other malicious actions via arbitrary root code execution. Moreover, the Nimbuspwn vulnerabilities could potentially be leveraged as a vector for root access by more sophisticated threats, such as malware or ransomware, to achieve greater impact on vulnerable devices.

We discovered the vulnerabilities by listening to messages on the System Bus while performing code reviews and dynamic analysis on services that run as root, noticing an odd pattern in a systemd unit called networkd-dispatcher. Reviewing the code flow for networkd-dispatcher revealed multiple security concerns, including directory traversal, symlink race, and time-of-check-time-of-use race condition issues, which could be leveraged to elevate privileges and deploy malware or carry out other malicious activities. We shared these vulnerabilities with the relevant maintainers through Coordinated Vulnerability Disclosure (CVD) via Microsoft Security Vulnerability Research (MSVR). Fixes for these vulnerabilities, now identified as CVE-2022-29799 and CVE-2022-29800, have been successfully deployed by the maintainer of the networkd-dispatcher, Clayton Craft. We wish to thank Clayton for his professionalism and collaboration in resolving those issues. Users of networkd-dispatcher are encouraged to update their instances.

BlackCat/ALPHV Ransomware Indicators of Compromise

 This FLASH is part of a series of FBI reports to disseminate known indicators of compromise (IOCs) and tactics, techniques and procedures (TTPs) associated with ransomware variants identified through FBI investigations. As of March 2022, BlackCat/ALPHV ransomware as a service (RaaS) had compromised at least 60 entities worldwide and is the first ransomware group to do so successfully using RUST, considered to be a more secure programming language that offers improved performance and reliable concurrent processing. BlackCat-affiliated threat actors typically request ransom payments of several million dollars in Bitcoin and Monero but have accepted ransom payments below the initial ransom demand amount. Many of the developers and money launderers for BlackCat/ALPHV are linked to Darkside/Blackmatter, indicating they have extensive networks and experience with ransomware operations.

High‑impact UEFI vulnerabilities discovered in Lenovo consumer laptops

ESET researchers have discovered and analyzed three vulnerabilities affecting various Lenovo consumer laptop models. The first two of these vulnerabilities – CVE-2021-3971CVE-2021-3972 – affect UEFI firmware drivers originally meant to be used only during the manufacturing process of Lenovo consumer notebooks. Unfortunately, they were mistakenly included also in the production BIOS images without being properly deactivated. These affected firmware drivers can be activated by attacker to directly disable SPI flash protections (BIOS Control Register bits and Protected Range registers) or the UEFI Secure Boot feature from a privileged user-mode process during OS runtime. It means that exploitation of these vulnerabilities would allow attackers to deploy and successfully execute SPI flash or ESP implants, like LoJax or our latest UEFI malware discovery ESPecter, on the affected devices.

To understand how we were able to find these vulnerabilities, consider the firmware drivers affected by CVE‑2021-3971. These drivers immediately caught our attention by their very unfortunate (but surprisingly honest) names: SecureBackDoor and SecureBackDoorPeim. After some initial analysis, we discovered other Lenovo drivers sharing a few common characteristics with the SecureBackDoor* drivers: ChgBootDxeHook and ChgBootSmm. As it turned out, their functionality was even more interesting and could be abused to disable UEFI Secure Boot (CVE-2021-3972).

In addition, while investigating above mentioned vulnerable drivers, we discovered the third vulnerability: SMM memory corruption inside the SW SMI handler function (CVE-2021-3970). This vulnerability allows arbitrary read/write from/into SMRAM, which can lead to the execution of malicious code with SMM privileges and potentially lead to the deployment of an SPI flash implant.

We reported all discovered vulnerabilities to Lenovo on October 11th, 2021. Altogether, the list of affected devices contains more than one hundred different consumer laptop models with millions of users worldwide, from affordable models like Ideapad-3 to more advanced ones like Legion 5 Pro-16ACH6 H or Yoga Slim 9-14ITL05. The full list of affected models with active development support is published in the Lenovo Advisory.

In addition to the models listed in the advisory, several other devices we reported to Lenovo are also affected, but won’t be fixed due to them reaching End Of Development Support (EODS). This includes devices where we spotted reported vulnerabilities for the first time: Ideapad 330-15IGM and Ideapad 110-15IGR. The list of such EODS devices that we have been able to identify will be available in ESET’s vulnerability disclosures repository.

Lenovo confirmed the vulnerabilities on November 17th, 2021, and assigned them the following CVEs:

Largest Mobile Chipset Manufacturers used Vulnerable Audio Decoder

Highlights:

·        Check Point Research discovered vulnerabilities in the ALAC format that could have led an attacker to remotely get access to its media and audio conversations

·        MediaTek and Qualcomm, the two largest mobile chipset manufacturers in the world, used the ALAC audio coding in their widely distributed mobile handsets, putting millions of Android users’ privacy at risk

·        Research, dubbed “ALHACK” finds Two thirds of all smartphones sold in 2021 are vulnerable

·        Qualcomm and MediaTek acknowledged the vulnerabilities flagged by CPR, putting patches and fixes in response

Background

The Apple Lossless Audio Codec (ALAC), also known as Apple Lossless, is an audio coding format, developed by Apple Inc. and first introduced in 2004 for lossless data compression of digital music.

In late 2011 Apple made the codec open source. Since then, the ALAC format has been embedded in many non-Apple audio playback devices and programs, including Android-based smartphones, Linux and Windows media players and converters.

Since then Apple has been updating the proprietary version of the decoder several times, fixing and patching security issues, but the shared code has not been patched since 2011. Many third-party vendors use the Apple-supplied code as the basis for their own ALAC implementations, and it’s fair to assume that many of them do not maintain the external code.

Check Point Research has discovered that Qualcomm and MediaTek, two of the largest mobile chipset makers in the world, ported the vulnerable ALAC code into their audio decoders, which are used in more than half of all smartphones worldwide. According to IDC, 48.1% of all Android phones sold in the US are powered by MediaTek as of Q4 2021, while Qualcomm currently holds 47% of the market.

What did we find and what is the potential threat?

The ALAC issues our researchers found could be used by an attacker for remote code execution attack (RCE) on a mobile device through a malformed audio file. RCE attacks allow an attacker to remotely execute malicious code on a computer. The impact of an RCE vulnerability can range from malware execution to an attacker gaining control over a user’s multimedia data, including streaming from a compromised machine’s camera.

In addition, an unprivileged Android app could use these vulnerabilities to escalate its privileges and gain access to media data and user conversations.

Responsible disclosure

Check Point Research responsibly disclosed the information to MediaTek and Qualcomm and worked closely in collaboration with both vendors to make sure these vulnerabilities were fixed.

MediaTek assigned CVE-2021-0674 and CVE-2021-0675 to the ALAC issues. The vulnerabilities were already fixed and published in the December 2021 MediaTek Security Bulletin. Qualcomm released the patch for CVE-2021-30351 in the December 2021 Qualcomm Security Bulletin.

TraderTraitor: North Korean State-Sponsored APT Targets Blockchain Companies

 Summary

Actions to take today to mitigate cyber threats to cryptocurrency:
• Patch all systems.
• Prioritize patching known exploited vulnerabilities.
• Train users to recognize and report phishing attempts.
• Use multifactor authentication.

The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the U.S. Treasury Department (Treasury) are issuing this joint Cybersecurity Advisory (CSA) to highlight the cyber threat associated with cryptocurrency thefts and tactics used by a North Korean state-sponsored advanced persistent threat (APT) group since at least 2020. This group is commonly tracked by the cybersecurity industry as Lazarus Group, APT38, BlueNoroff, and Stardust Chollima. For more information on North Korean state-sponsored malicious cyber activity, visit https://www.us-cert.cisa.gov/northkorea.

The U.S. government has observed North Korean cyber actors targeting a variety of organizations in the blockchain technology and cryptocurrency industry, including cryptocurrency exchanges, decentralized finance (DeFi) protocols, play-to-earn cryptocurrency video games, cryptocurrency trading companies, venture capital funds investing in cryptocurrency, and individual holders of large amounts of cryptocurrency or valuable non-fungible tokens (NFTs). The activity described in this advisory involves social engineering of victims using a variety of communication platforms to encourage individuals to download trojanized cryptocurrency applications on Windows or macOS operating systems. The cyber actors then use the applications to gain access to the victim’s computer, propagate malware across the victim’s network environment, and steal private keys or exploit other security gaps. These activities enable additional follow-on activities that initiate fraudulent blockchain transactions.

The U.S. government previously published an advisory about North Korean state-sponsored cyber actors using AppleJeus malware to steal cryptocurrency: AppleJeus: Analysis of North Korea’s Cryptocurrency Malware. The U.S. government has also previously published advisories about North Korean state-sponsored cyber actors stealing money from banks using custom malware:

This advisory provides information on tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) to stakeholders in the blockchain technology and cryptocurrency industry to help them identify and mitigate cyber threats against cryptocurrency.
