Researchers broke the browsers built into VS Code, Cursor, Copilot, Codex and Claude Desktop

Forever Security found ways out of the built-in browsers in five AI coding assistants: Cursor, GitHub Copilot, OpenAI’s Codex, Microsoft’s VS Code and Anthropic’s Claude Desktop. In all five, a web page or a local file reached the computer behind the browser. Cursor ran attacker code, Copilot showed a fake address, and Codex, VS Code and Claude Desktop let a single local file read the rest of the disk. Two of those h…

Webinar: How to Build AI Threat Readiness Into Your Security Operations

Security teams have spent years trying to detect threats faster. AI is changing the harder part: how much time defenders have left to act. Advanced AI models can now help attackers discover vulnerabilities, generate exploit code, and move through weaknesses faster than traditional security processes were built to handle. The challenge is no longer just finding another vulnerability or

Vulnerability exploitation rising as the root cause of many breaches

More evidence has emerged that attackers are turning to vulnerabilities rather than phishing as a means for breaking into corporate systems. Incident response firm LevelBlue’s Q3 findings show that vulnerability exploitation accounted for 14% of initial access cases, up from 4% in Q2. The finding represents more of a comeback than a fresh surge because in Q1 LevelBlue already recorded vulnerabilities as the root caus…
