High-severity security vulnerabilities have been disclosed in different endpoint detection and response (EDR) and antivirus (AV) products that could be exploited to turn them into data wipers. "This wiper runs with the permissions of an unprivileged user yet has the ability to wipe almost any file on a system, including system files, and make a computer completely unbootable," SafeBreach Labs researcher Or Yair  said . "It does all that without implementing code that touches the target files, making it fully undetectable." EDR software, by design, are capable of continually scanning a machine for potentially suspicious and malicious files, and taking appropriate action, such as deleting or quarantining them. The idea, in a nutshell, is to trick vulnerable security products into deleting legitimate files and directories on the system and render the machine inoperable by making use of specially crafted paths. This is achieved by taking advantage of what's ca...

Two high-severity security vulnerabilities, which went undetected for several years, have been discovered in a  legitimate driver  that's part of Avast and AVG antivirus solutions. "These vulnerabilities allow attackers to escalate privileges enabling them to disable security products, overwrite system components, corrupt the operating system, or perform malicious operations unimpeded," SentinelOne researcher Kasif Dekel  said  in a report shared with The Hacker News. Tracked as CVE-2022-26522 and CVE-2022-26523, the flaws reside in a legitimate anti-rootkit kernel driver named aswArPot.sys and are said to have been introduced in Avast version 12.1, which was released in June 2016. Specifically, the shortcomings are rooted in a socket connection handler in the kernel driver that could lead to privilege escalation by running code in the kernel from a non-administrator user, potentially causing the operating system to crash and display a blue screen of death ( BSo...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
