Zero-Day Alert: Google Chrome Under Active Attack, Exploiting New Vulnerability

Zero-Day Alert: Google Chrome Under Active Attack, Exploiting New Vulnerability

Nov 29, 2023 Zero-Day / Web Browser
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
New P2PInfect Worm Targeting Redis Servers on Linux and Windows Systems

New P2PInfect Worm Targeting Redis Servers on Linux and Windows Systems

Jul 20, 2023 Malware / Cyber Threat
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  HeadCrab  over the past ye
How to Find and Fix Risky Sharing in Google Drive

How to Find and Fix Risky Sharing in Google Drive

Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ
Muhstik Botnet Targeting Redis Servers Using Recently Disclosed Vulnerability

Muhstik Botnet Targeting Redis Servers Using Recently Disclosed Vulnerability

Mar 28, 2022
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 another s
