New Linux RCE Vulnerability Leaks Ahead of Disclosure - Allows Arbitrary Code Execution via CUPS Print Scheduler

A new vulnerability was recently discovered in a widely used print server that is installed by default on many Linux and Unix-based systems with a graphical user interface. The primary attack vector for the vulnerability is the CUPS (Common Unit Printing System) print scheduler, specifically cups-browsed, and has the potential to execute code remotely with zero user interaction required.

The vulnerability has reportedly been given a CVSS score of 9.9 by RHEL and Canonical, although this score is hotly debated, with some arguing it should have a lower score, because, although code can be remotely downloaded to the system, it cannot be executed without user intervention. Fortunately, there is no evidence of the vulnerability having been exploited, although the disclosure was leaked online ahead of a planned private reveal in October, prompting the developer that discovered the vulnerability to post the full explanation in a write-up on their blog. This being the case, the vulnerability could very well start being exploited by malicious actors.

AMD Response to "ZENHAMMER: Rowhammer Attacks on AMD Zen-Based Platforms"

On February 26, 2024, AMD received new research related to an industry-wide DRAM issue documented in "ZENHAMMER: Rowhammering Attacks on AMD Zen-based Platforms" from researchers at ETH Zurich. The research demonstrates performing Rowhammer attacks on DDR4 and DDR5 memory using AMD "Zen" platforms.

"Double Dragon Gaiden: Rise of the Dragons" Devs Introduce "Sacred Reunion" DLC

The Lee family is reuniting once again to rid the streets of crime as Billy and Jimmy Lee's cousin, Sonny Lee, is joining Double Dragon Gaiden: Rise of the Dragons on April 4. An unconventional fighter, Sonny thrashes his enemies with a flurry of punches and kicks to prove he's just as powerful as his cousins. First appearing in Double Dragon 3: The Rosetta Stone, Sonny Lee joins Double Dragon Gaiden as part of the free Sacred Reunion DLC coming to PC and consoles. Sonny is the lazy, distant cousin of the Lee brothers, but just like Billy and Jimmy, he has practiced the art of Sōsetsuken since he was young. However, Sonny has a hard time keeping up. He opts to give the ancient technique his own creative spin and now wanders the streets to test the might of his new moves.

Also joining Sonny in the Sacred Reunion DLC is the secret assassin Ranzou and one additional mystery fighter. Ranzou is a mysterious young ninja from a secret organization, known as The Secret Society of Ninjas. He has no stake in the fate of New York, but he is sent here by his organization as a test of his abilities. Along with the new characters, the Sacred Reunion DLC will include Survival mode, Versus mode and online co-op. As a fighter, Sonny distinguishes himself as a rushdown/offensive warrior. He executes an action attack similar to a quick breakdance maneuver that travels a short distance and covers threats from all directions. Despite his Sōsetsuken roots, we wanted to ensure that Sonny is his own character, and he is designed to play differently from Billy and Jimmy with much more eccentric moves. His role as the familial outcast significantly influences his fighting style, resulting in a blend of showboating and non-traditional stances. Sonny's distinctive approach to combat reflects his individuality within the family dynamic, which gives him more depth and personality, allowing him to shine brighter in the game.

Microsoft Reveals Cyberattack & Theft of Internal Source Code

We have provided an update on the nation-state attack that was detected by the Microsoft Security Team on January 12, 2024. As we shared, on January 19, the security team detected this attack on our corporate email systems and immediately activated our response process. The Microsoft Threat Intelligence investigation identified the threat actor as Midnight Blizzard, the Russian state-sponsored actor also known as NOBELIUM. As we said at that time, our investigation was ongoing, and we would provide additional details as appropriate.

In recent weeks, we have seen evidence that Midnight Blizzard is using information initially exfiltrated from our corporate email systems to gain, or attempt to gain, unauthorized access. This has included access to some of the company's source code repositories and internal systems. To date we have found no evidence that Microsoft-hosted customer-facing systems have been compromised. It is apparent that Midnight Blizzard is attempting to use secrets of different types it has found. Some of these secrets were shared between customers and Microsoft in email, and as we discover them in our exfiltrated email, we have been and are reaching out to these customers to assist them in taking mitigating measures. Midnight Blizzard has increased the volume of some aspects of the attack, such as password sprays, by as much as 10-fold in February, compared to the already large volume we saw in January 2024.

IBM Intros AI-enhanced Data Resilience Solution - a Cyberattack Countermeasure

Cyberattacks are an existential risk, with 89% of organizations ranking ransomware as one of the top five threats to their viability, according to a November 2023 report from TechTarget's Enterprise Strategy Group, a leading analyst firm. And this is just one of many risks to corporate data—insider threats, data exfiltration, hardware failures, and natural disasters also pose significant danger. Moreover, as the just-released 2024 IBM X-Force Threat Intelligence Index states, as the generative AI market becomes more established, it could trigger the maturity of AI as an attack surface, mobilizing even further investment in new tools from cybercriminals. The report notes that enterprises should also recognize that their existing underlying infrastructure is a gateway to their AI models that doesn't require novel tactics from attackers to target.

To help clients counter these threats with earlier and more accurate detection, we're announcing new AI-enhanced versions of the IBM FlashCore Module technology available inside new IBM Storage FlashSystem products and a new version of IBM Storage Defender software to help organizations improve their ability to detect and respond to ransomware and other cyberattacks that threaten their data. The newly available fourth generation of FlashCore Module (FCM) technology enables artificial intelligence capabilities within the IBM Storage FlashSystem family. FCM works with Storage Defender to provide end-to-end data resilience across primary and secondary workloads with AI-powered sensors designed for earlier notification of cyber threats to help enterprises recover faster.

New LeftoverLocals Vulnerability Threatens LLM Security on Apple, AMD, and Qualcomm GPUs

New York-based security firm Trail of Bits has identified a security vulnerability with various GPU models, which include AMD, Qualcomm, and Apple. This vulnerability, named LeftoverLocals, could potentially allow attackers to steal large amounts of data from a GPU's memory. Mainstream client-GPUs form a sizable chunk of the hardware accelerating AI and LLMs, as they cost a fraction of purpose-built data-center GPUs, and are available in the retail market. Unlike CPUs, which have undergone extensive hardening against data leaks, GPUs were primarily designed for graphics acceleration and lack similar data privacy architecture. To our knowledge, none of the client GPUs use virtualization with their graphics memory. Graphics acceleration in general is a very memory sensitive application, and requires SIMD units to have bare-metal access to memory, with as little latency as possible.

First the good news—for this vulnerability to be exploited, it requires the attacker to have access to the target device with the vulnerable GPU (i.e. cut through OS-level security). The attack could break down data silos on modern computers and servers, allowing unauthorized access to GPU memory. The potential data breach could include queries, responses generated by LLMs, and the weights driving the response. The researchers tested 11 chips from seven GPU makers and found the vulnerability in GPUs from Apple, AMD, and Qualcomm. While NVIDIA, Intel, and Arm first-party GPUs did not show evidence of the vulnerability, Apple, Qualcomm, and AMD confirmed to wired that their GPUs are affected, and that they're working on a security response. Apple has released fixes for its latest M3 and A17 processors, but older devices with previous generations of Apple silicon remain vulnerable. Qualcomm is providing security updates, and AMD plans to offer mitigations through driver updates in March 2024.

Red Sea Attacks to Affect PC Part Shipments to Europe

The recent attacks on cargo ships in the Red Sea are affecting not only oil shipments, but also cargo ships from Asia to Europe. All major carriers such as CMA CGM, Cosco, Evergreen, Hapag-Lloyd, Maersk, MSC and so forth are affected and all have delayed their shipments through the area. A coordinated security action called Operations Prosperity Guardian which includes over half a dozen nations so far, is getting ready to guide shipments through the affected area by Yemen, but it'll lead to slower shipments through the area.

TechPowerUp has already received reports from sources in Taiwan that their products are on some of these ships that are now stuck waiting for naval escorts through the area. However, it appears that there might be shortages of some computer components for the foreseeable future, alongside many other products that are being shipped this route and onwards via the Suez Canal. According to the BBC, it takes 25.5 days on average to ship goods from Taiwan to the Netherlands via the Red Sea and Suez Canal whereas the only alternative route via the Cape of Good Hope takes 34 days and adds extra fuel costs. Regardless of the extra shipping times and costs, it appears some shipping companies are willing to take the longer route to avoid being attacked. This is likely to have a knock on effect on prices for a lot of consumer goods in Europe, so if you haven't bought that hardware you've been holding off getting, now might be as good a time as any.

LogoFAIL Vulnerability Affects Almost Every PC Running Windows and Linux

Binarly's research team has discovered a collection of security vulnerabilities known as "LogoFAIL", which affects image parsing components within the UEFI firmware of a wide array of devices. These vulnerabilities are especially concerning because they are embedded within the reference code provided by Independent BIOS Vendors (IBVs), affecting not just a single vendor but a broad spectrum of devices that utilize this code. LogoFAIL is particularly dangerous because it allows attackers to bypass crucial security measures such as Secure Boot and Intel Boot Guard by executing a payload during the device's boot process. This is achieved by storing malicious images on the EFI System Partition or within unsigned sections of firmware updates. This method can compromise system security deeply without altering the runtime integrity of the bootloader or firmware, unlike other threats such as BlackLotus or BootHole.

The potential reach of LogoFAIL vulnerability is rather wide, with millions of consumer and enterprise-grade devices from various vendors, including ones like Intel, Acer, and Lenovo, being vulnerable. The exact list of affected devices is still undetermined, but the prevalence of the IBVs' code across numerous devices suggests that the impact could be widespread, with both Windows and Linux users being affected. Only PCs that don't allow any logotype displayed in the UEFI during the boot process are safe. Apple's Macs are secure as they don't allow any add-on images during boot, and some OEM prebuilt PCs, like the ones from Dell, don't allow images in the UEFI. Some makers like Lenovo, AMI, and Insyde have already published notes about cautiously uploading custom images to the UEFI and providing BIOS updates. Consumers and enterprises must check with their OEMs and IBVs for BIOS microcode updates to patch against this vulnerability.
Below, you can see the proof of concept in a YouTube video.

AMD EPYC CPUs Affected by CacheWarp Vulnerability, Patches are Already Available

Researchers at Graz University of Technology and the Helmholtz Center for Information Security have released their paper on CacheWarp—the latest vulnerability affecting some of the prior generation AMD EPYC CPUs. Titled CVE-2023-20592, the exploit targets first-generation EPYC Naples, second-generation EPYC Rome, and third-generation EPYC Milan. CacheWarp operates by exploiting a vulnerability in AMD's Secure Encrypted Virtualization (SEV) technology, specifically targeting the SEV-ES (Encrypted State) and SEV-SNP (Secure Nested Paging) versions. The attack is a software-based fault injection technique that manipulates the cache memory of a virtual machine (VM) running under SEV. It cleverly forces modified cache lines of the guest VM to revert to their previous state. This action circumvents the integrity checks that SEV-SNP is designed to enforce, allowing the attacker to inject faults without being detected.

Unlike attacks that rely on specific guest VM vulnerabilities, CacheWarp is more versatile and dangerous because it does not depend on the characteristics of the targeted VM. It exploits the underlying architectural weaknesses of AMD SEV, making it a broad threat to systems relying on this technology for security. The CacheWarp attack can bypass robust security measures like encrypted virtualization, posing a significant risk to data confidentiality and integrity in secure computing environments. AMD has issued an update for EPYC Milan with a hot-loadable microcode patch and updated the firmware image without any expected performance degradation. And for the remaining generations, AMD states that no mitigation is available for the first or second generations of EPYC processor (Naples and Rome) since the SEV and SEV-ES features are not designed to protect guest VM memory integrity, and the SEV-SNP is not available.

That, in turn, translates into greater security and higher SOC productivity.

Zenbleed Vulnerability Affects All AMD Zen 2 CPUs

A new vulnerability has been discovered in AMD Zen 2 based CPUs by Tavis Ormandy, a Google Information Security researcher. Ormandy has named the new vulnerability Zenbleed—also known as CVE-2023-20593—and it's said to affect all Zen 2 based AMD processors, which means Ryzen 3000, 4000 and 5000-series CPUs and APUs, as well as EPYC server chips. The reason why Zenbleed is of concern is because it doesn't require a potential attacker to have physical access to the computer or server in question and it's said to be possible to trigger the vulnerability via executing a javascript on a webpage. This means that the attack vector ends up being massive, at least when we're talking about something like a webhosting company.

Zenbleed is said to allow a potential attacker to gain access to things like encryption keys and user logins via triggering something called "the XMM Register Merge Optimization2, followed by a register rename and a mispredicted vzeroupper." Apparently this requires some precision for the vulnerability to work, but due to these registers being used system wide, even a sandboxed attacker can gain access to them. AMD has already issued a patch for its EPYC server CPUs, which obviously are the most vulnerable systems in question and the company is planning to release patches for all of its Zen 2 based CPUs before the end of the year. Hit up the source links for more details about Zenbleed.

CISA Warns About Mirai Botnet Exploit on Some TP-Link Routers

Owners of TP-Link routers ought to heed a warning from the US government's Cybersecurity and Infrastructure Security Agency (CISA), as at least one router model from the company is vulnerable to known exploits. The exploit is actively targeted by Mirai botnet operators and it allows for injection of commands that could allow them to take over the routers via remote code execution (RCE) software. The router from TP-Link that is known to be vulnerable to the exploits is the Archer AX-21, a fairly recent entry level AX1800 Wi-Fi 6 model that is sold globally by the company.

The specific exploit for the Archer AX-21 is tracked as CVE-2023-1389 and is affecting all Archer AX-21 routers with a firmware version older than 1.1.4 2023019, as it's said to address the vulnerabilities. Users who have linked their router to a TP-Link cloud account and allow for automatic updates should already have had their router firmware automatically updated, but everyone else should update their router firmware as soon as possible. There have already been reports of the exploit being actively used by the Mirai botnet to take over routers in Eastern Europe as of the middle of last month, but further parts of the world aren't spared from attacks either by now. Routers might often be devices that are forgotten in a corner somewhere, but it's important to keep the firmware up to date, especially as they are increasingly becoming the target of hackers.

AMD faulTPM Exploit Targets Zen 2 and Zen 3 Processors

Researchers at the Technical University of Berlin have published a paper called "faulTPM: Exposing AMD fTPMs' Deepest Secrets," highlighting AMD's firmware-based Trusted Platform Module (TPM) is susceptible to the new exploit targeting Zen 2 and Zen 3 processors. The faulTPM attack against AMD fTPMs involves utilizing the AMD secure processor's (SP) vulnerability to voltage fault injection attacks. This allows the attacker to extract a chip-unique secret from the targeted CPU, which is then used to derive the storage and integrity keys protecting the fTPM's non-volatile data stored on the BIOS flash chip. The attack consists of a manual parameter determination phase and a brute-force search for a final delay parameter. The first step requires around 30 minutes of manual attention, but it can potentially be automated. The second phase consists of repeated attack attempts to search for the last-to-be-determined parameter and execute the attack's payload.

Once these steps are completed, the attacker can extract any cryptographic material stored or sealed by the fTPM regardless of authentication mechanisms, such as Platform Configuration Register (PCR) validation or passphrases with anti-hammering protection. Interestingly, BitLocker uses TPM as a security measure, and faulTPM compromises the system. Researchers suggested that Zen 2 and Zen 3 CPUs are vulnerable, while Zen 4 wasn't mentioned. The attack requires several hours of physical access, so remote vulnerabilities are not a problem. Below, you can see the $200 system used for this attack and an illustration of the physical connections necessary.

Bad Week for MacOS Security: Two New Malware Threats Identified

As market share of Apple's ARM based Mac computers has increased, so too have efforts to compromise them by previously uninterested hacker groups. A recent string of malware created specifically for macOS has shown that these groups are turning their gaze toward the generally well protected Mac ecosystem. One of these new malware threats, discovered by Jamf Threat Labs and dubbed 'RustBucket,' acts as a simple third-party PDF viewer. The application itself does nothing malicious until a specific PDF is opened which includes an encoded key that triggers a connection to be made between the attacker's server and the victim's Mac, and a small malicious payload to be downloaded. The initial payload begins running system recon commands to determine the machine information, and then downloads a third stage payload which gives the attackers further access to the underlying operating system. All stages after the user opens the PDF are run silently in the background. The PDF viewer used as the catalyst for this hack does require manually overriding Apple's Gatekeeper as it carries no signature, so the obvious step to mitigate this attack is to not use third-party apps or services aside from those curated on Apple's App Store.

The second macOS malware of the week was discovered by Cyble Research and Intelligence Labs (CRIL) being offered for a paltry $1,000 USD per month on a Telegram channel, with the malware going by the name "Atomic macOS Stealer" or "AMOS." This malware has capabilities to scrape keychain passwords, system information, files from the desktop and documents folders, the macOS user password, browser auto-fills, passwords, cookies, wallets, and stored credit card info. The malware is especially adapted to go after cryptowallets with Cyble citing examples such as Electrum, Binance, Exodus, Atomic, and Coinomi. Cyble notes that they've seen the malware receiving active development to improve its capabilities and the threat actors even offering management software and web panels for keeping track of victimized machines, all with a logging system that dumps to Telegram. The current attack vector is a simple Golang.dmg file which installs the malware, so this does appear to require direct machine access. However once installed, "AMOS" does its handiwork without detection and sends a compressed file off to the attacker's server with all the information it collected.

Money Message Ransomware Group Apparently Behind MSI Breach

It appears that MSI's data breach is more significant than originally thought and according to recent information, a new ransomware group known as "Money Message" was behind the attack, stealing databases and source code from MSI's network.

According to a report over from the BleepingComputer, Money Message claims to have stolen 1.5 TB of data from MSI's systems, including CTMS and ERP databases, software source code, private keys, and BIOS firmware. Money Message is threatening to publish these allegedly stolen documents and asking a ransom payment of $4 million. MSI has already warned its customers about the cyberattack, has started the "relevant defense mechanisms," and has been gradually restoring its systems back to normal operations.

MSI Warns Customers After Cyberattack on its Systems

MSI has issued a warning to its customers after the company detected it has suffered from a cyberattack on its "information systems". Although it's not clear exactly what was attacked, the company has detected what it calls anomalies on its network and has since kicked in "relevant defense mechanisms" which among other things included reporting the incident to local law enforcement agencies and cybersecurity units.

MSI states that the company has been gradually restoring its systems back to normal operations and that the attack has had negligible impact on its business. However, MSI is warning its customers not to download MSI BIOS/UEFI/firmware updates or drivers from any other source than MSI's official website, or any of its software. Although MSI doesn't state if whoever performed the attack might have gotten hold of any of its software, this seems to suggest such things and it's clear that MSI is worried that there might be software appearing in the near future that will be compromised in one way or another.

Google's Project Zero Discovers 18 Zero-Day Vulnerabilities in Exynos Chipsets

Google's internal team Project Zero, dedicated to the discovery and patching of zero-day vulnerabilities in mobile hardware, software, web browsers and open source libraries disclosed a series of vulnerabilities in Samsung's Exynos chipsets featured across a wide range of mobile devices. Four of these critical vulnerabilities allow for internet-to-baseband remote code execution, and testing conducted by Project Zero confirmed that an attacker can compromise a phone at the baseband level with only the victim's phone number. They believe that with sufficient skill an attacker could exploit these vulnerabilities completely silently and remotely. The fourteen other vulnerabilities are related but considered to not be as critical as they require a more extensive setup including a malicious mobile network operator or local access to the targeted device.

Due to the severity of the main four critical vulnerabilities Project Zero has delayed full disclosure on how the exploit works stating:
Due to a very rare combination of level of access these vulnerabilities provide and the speed with which we believe a reliable operational exploit could be crafted, we have decided to make a policy exception to delay disclosure for the four vulnerabilities that allow for Internet-to-baseband remote code execution.

Microsoft Releases Windows Patches, Fixes Actively Exploited Zero-Day Vulnerabilities

Microsoft today unleashed a slew of updates for its March Patch Tuesday to address around 80 security vulnerabilities in the wild. To begin, Windows 10 patches KB5023696 and KB5023697 address system and security issues in Windows 10 versions 22H2, 21H2, 21H1, 1809, and 1607 as well as Windows Server 2016. These are being deployed as non-optional updates and will be automatically installed via Windows Update (unless you run a modified or locked down install). Windows 10 1507 also received a small patch, KB5023713, which similarly addresses security fixes as well as hyperlinks in Excel.

Microsoft today also releases fixes for two critical zero-day vulnerabilities that were being actively exploited as far back as April of 2022. The two exploited vulnerabilities are CVE-2023-23397 and CVE-2023-24880. CVE-2023-23397 is an elevated privilege attack that allows crafting special emails that can force a target's device to connect to remote URLs and transmit the Windows account's Net-NTLMv2 hash. CVE-2023-24880 is a Windows SmartScreen vulnerability that can be exploited to create executables which bypass the Windows Mark of the Web security warning.

New Vulnerabilities Found in TPM 2.0 Library That Could be a Potential Threat to Billions of Devices

A pair of new vulnerabilities has been found in the TPM 2.0 library by cybersecurity company Quarkslab, that has security experts worried, as both of the flaws have potential far reaching implications. The two vulnerabilities go under the CVE identifiers of CVE-2023-1017 and CVE-2023-1018, where the first one allows for out-of-bounds writes, whereas the second one enables out-of-bounds reads, also known as buffer overflow vulnerabilities. This in itself might not sound particularly concerning, but as both can be triggered from user-mode applications, they're a pretty big deal, as it would enable malicious commands to be sent to a TPM 2.0 module, which could in turn enable malicious software to be installed on the device with the TPM 2.0 module.

According to Quarkslab, billions of devices could be affected, as TPM 2.0 authentication modules are used in everything from servers to IoT devices and has been the main hardware-based crypto solution for almost a decade by now. The attacker using the vulnerabilities would have to know what they're doing to be able to take advantage of these two flaws in TPM 2.0, but as it relies on the TPM command interface, there's no easy way to protect against an attack, if someone has gained user access to the system in question. The Trusted Computing Group (TCG) which is in charge of the TPM standard, has already issued an errata which includes instructions on how to address the two vulnerabilities and we're like to see updates from all major hardware vendors as they see fit.

Mail-Bomb Attack Targets Northeastern University VR Lab

Law enforcement is investigating an alleged mail-bomb attack towards the Northeastern University's VR department (Boston). A 45-year-old mailroom employee was caught in an explosion late Tuesday evening after opening a parcel containing a hard plastic case, leading the improvised explosive device to activate. Luckily, the employee survived the attack with only lacerations on his hands.

A low-tech way of delivering explosive payloads, mail bombing in the US rose to prominence through the actions of the Unabomber. Now, it seems that this delivery method is once again being weaponized for political purposes, as the package carried with a note (described as "rambling") that criticized Meta CEO Mark Zuckerberg and the relationship between university VR research and private interests. Northeastern University hosts several VR-oriented facilities, including an Immersive Media Labs Suite that "includes technologies for design, development, and exploration of virtual worlds, AR/VR/XR, and 360 video." It remains to be seen if this is a lone event or if it's a part of a more elaborate strategy of preventing change through fear.
