CERT UEFI Parser: Open-source tool exposes UEFI architecture to uncover vulnerabilities

Help Net Security
Critical

Overview

The CERT Coordination Center has launched the CERT UEFI Parser, an open-source tool designed to help cybersecurity researchers analyze Unified Extensible Firmware Interface (UEFI) software. This tool aims to simplify the examination of UEFI code, making it easier to identify various types of vulnerabilities that can be challenging to detect. By applying program analysis techniques, the parser extracts architectural details that can reveal security weaknesses within UEFI firmware. This initiative is particularly important as UEFI is critical in the boot process of modern devices, and vulnerabilities in this area can lead to serious security risks. The tool is available through the Software Engineering Institute at Carnegie Mellon University, marking a significant step forward in UEFI security research.

AI Slop Isn't Just for Social Media; It's Ruining Cyberattacks, Too

darkreading

The article argues that artificial intelligence (AI) is making cyberattacks less sophisticated rather than more dangerous. It claims that serious cybercriminals are not utilizing AI tools extensively, suggesting that these technologies are not living up to the hype in the cybersecurity realm. Instead, the author indicates that traditional methods of attack are still prevalent and effective. This perspective raises questions about the true impact of AI on cybersecurity and whether it is genuinely enhancing threats or merely complicating the landscape. Companies and security teams should remain vigilant, as the article hints at a disconnect between AI capabilities and practical, malicious use.

Critical PwnEscape Linux Kernel Vulnerability Lets Guest VMs Read Host Memory

The Hacker News

A serious vulnerability in the Linux kernel, identified as CVE-2026-99999 and dubbed PwnEscape, has been revealed, allowing virtual machines (VMs) to access the memory of the host system. This flaw is located within the networking code of the Linux kernel, meaning it affects multiple cloud environments, not just one particular setup. A researcher demonstrated this vulnerability on Vercel's cloud sandboxes, and the company confirmed the issue. This breach poses significant risks, as it could enable attackers to extract sensitive data from the host machine, potentially compromising the integrity and confidentiality of the systems involved. Companies using Linux-based virtual machines should be vigilant and take appropriate measures to safeguard their environments.

Hackers hijack D-Link, Ubiquiti devices to resell your stolen bandwidth

BleepingComputer

A recent campaign has targeted D-Link and Ubiquiti devices across 34 countries, allowing hackers to hijack these devices to create a commercial residential proxy network. This practice, known as proxyjacking, enables attackers to monetize stolen bandwidth from unsuspecting users. The impact is significant as it not only affects individual users' internet speeds and data privacy but also raises concerns about the security of these widely used devices. Users whose devices have been compromised may find their internet connections slower and could potentially face additional security risks if their devices are manipulated for illicit purposes. The situation underscores the need for users to secure their devices and remain vigilant against unauthorized access.
