Google has rolled out security updates to fix seven security issues in its Chrome browser, including a zero-day that has come under active exploitation in the wild. Tracked as  CVE-2023-6345 , the high-severity vulnerability has been described as an integer overflow bug in Skia, an open source 2D graphics library. Benoît Sevens and Clément Lecigne of Google's Threat Analysis Group (TAG) have been credited with discovering and reporting the flaw on November 24, 2023. As is typically the case, the search giant  acknowledged  that "an exploit for CVE-2023-6345 exists in the wild," but stopped short of sharing additional information surrounding the nature of attacks and the threat actors that may be weaponizing it in real-world attacks. It's worth noting that Google released patches for a similar integer overflow flaw in the same component ( CVE-2023-2136 ) in April 2023 that had also come under active exploitation as a zero-day, raising the possibility that CVE-202...

Cybersecurity researchers have uncovered a new cloud targeting, peer-to-peer (P2P) worm called  P2PInfect  that targets vulnerable Redis instances for follow-on exploitation. "P2PInfect exploits Redis servers running on both Linux and Windows Operating Systems making it more scalable and potent than other worms," Palo Alto Networks Unit 42 researchers William Gamazo and Nathaniel Quist  said . "This worm is also written in Rust, a highly scalable and cloud-friendly programming language." It's estimated that as many as 934 unique Redis systems may be vulnerable to the threat. The first known instance of P2PInfect was detected on July 11, 2023. A notable characteristic of the worm is its ability to infects vulnerable Redis instances by exploiting a critical Lua sandbox escape vulnerability,  CVE-2022-0543  (CVSS score: 10.0), which has been previously exploited to deliver multiple  malware families  such as  Muhstik ,  Redigo , and  H...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

Muhstik, a botnet infamous for propagating via web application exploits, has been observed targeting Redis servers using a recently disclosed vulnerability in the database system. The vulnerability relates to  CVE-2022-0543 , a  Lua sandbox escape flaw  in the open-source, in-memory, key-value data store that could be abused to achieve remote code execution on the underlying machine. The vulnerability is rated 10 out of 10 for severity. "Due to a packaging issue, a remote attacker with the ability to execute arbitrary Lua scripts could possibly escape the Lua sandbox and execute arbitrary code on the host," Ubuntu noted in an advisory released last month. According to  telemetry data  gathered by Juniper Threat Labs, the attacks leveraging the new flaw are said to have commenced on March 11, 2022, leading to the retrieval of a malicious shell script ("russia.sh") from a remote server, which is then utilized to fetch and execute the botnet binaries from anoth...
