Microsoft on Thursday disclosed four medium-severity security flaws in the open-source OpenVPN software that could be chained to achieve remote code execution (RCE) and local privilege escalation (LPE). "This attack chain could enable attackers to gain full control over targeted endpoints, potentially resulting in data breaches, system compromise, and unauthorized access to sensitive information," Vladimir Tokarev of the Microsoft Threat Intelligence Community said . That said, the exploit, presented by Black Hat USA 2024, requires user authentication and an advanced understanding of OpenVPN's inner workings. The flaws affect all versions of OpenVPN prior to version 2.6.10 and 2.5.10. The list of vulnerabilities is as follows - CVE-2024-27459 - A stack overflow vulnerability leading to a Denial-of-service (DoS) and LPE in Windows CVE-2024-24974 - Unauthorized access to the "\\openvpn\\service" named pipe in Windows, allowing an attacker to remotely inte

The Russia-linked threat actor known as  APT28  has been linked to multiple ongoing phishing campaigns that employ lure documents imitating government and non-governmental organizations (NGOs) in Europe, the South Caucasus, Central Asia, and North and South America. "The uncovered lures include a mixture of internal and publicly available documents, as well as possible actor-generated documents associated with finance, critical infrastructure, executive engagements, cyber security, maritime security, healthcare, business, and defense industrial production," IBM X-Force  said  in a report published last week. The tech company is tracking the activity under the moniker  ITG05 , which is also known as Blue Athena, BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard (formerly Strontium), FROZENLAKE, Iron Twilight, Pawn Storm, Sednit, Sofacy, TA422, and UAC-028. The disclosure comes more than three months after the adversary was spotted using decoys related to the ongoing I

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic
