Cisco has disclosed multiple high-severity vulnerabilities in ClamAV that could allow unauthenticated remote attackers to disrupt antivirus scanning operations and cause denial-of-service conditions. The flaws affect the ClamAV parsers used by Cisco Secure Endpoint Connector on Windows, Linux, and macOS. The advisory, tracked as cisco-sa-clamav-WuuvVd26, was first published on August 7, 2026, and updated on August 10. Cisco assigned a High security impact rating to affected Windows systems, while Linux and macOS environments received a Medium rating. The company said the difference is due to…

Cybersecurity researchers have warned of a supply chain compromise impacting WordPress plugin vendor BdThemes, prompting the content management systems (CMS) platform's plugins team to temporarily disable their downloads. "Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said.

Microsoft has disclosed that Storm-1175, a financially motivated threat actor linked to China, has deployed a previously undocumented ransomware strain called StormEncryptor. The use of StormEncryptor marks a shift from the adversary's previous use of Medusa ransomware, the Microsoft Threat Intelligence Team said. "StormEncryptor is written in C++ and appends the file name extension .encrypted

Mozilla has scrapped the cryptographic key behind Firefox and Thunderbird downloads for Linux after an unencrypted copy of it was committed by mistake to one of the company's own private code repositories. That key is how a user, or a Linux distribution packaging the browser, confirms a downloaded Firefox tarball came from Mozilla and was not tampered with. That decision carries a cost for

AI is helping development teams produce far more code, far faster. But security teams still have to review vulnerabilities, manage dependencies, prioritize fixes, and control risk at human speed. When software output jumps 10 to 50 times, the problem is no longer just finding vulnerabilities. It is keeping security from becoming the bottleneck, or worse, losing control of what gets shipped.

Project CAV3RN is a modular espionage framework used against targets in Israel. This report expands on two earlier publications: the first was published in June 2026 as part of our Kaspersky Threat Intelligence Reporting service , and the second was published on Securelist the following month, further documenting the framework’s evolving architecture and C2 capabilities. Continued tracking of this cluster in early August 2026 uncovered several previously undocumented components that expanded the framework’s communication and orchestration capabilities. The main finding is a complex C2 module…

Despite the popularity of Claude Code, Cursor, GitHub Copilot, and OpenAI Codex, developers have plenty of complaints about AI coding tools. So researchers affiliated with York University and the University of Calgary in Canada decided to sift through developers' concerns about LLM-based integrated development environments (LIDEs) by analyzing Reddit discussions for common themes. Their findings suggest that the builders of such tools failed to prioritize security and privacy, leaving developers to defend themselves. Gias Uddin, associate professor at York University and a co-author of the…

Windows Plug and Play can be abused to fetch signed vendor software for an emulated USB device and execute privileged installation components that researchers chained to SYSTEM access on a fully updated Windows 11 machine. The same PnP path can be triggered over Remote Desktop without physical hardware when supported Plug and Play or low-level USB redirection is enabled; Microsoft says that
