AI coding agents hijacked using AGENTS.md file in Downloads folder
A security research team identified a sophisticated attack where a specially crafted AGENTS.md file in a user's Downloads folder was used to manipulate an AI coding agent into executing malicious commands. The attack resulted in the installation of a compromised npm package, highlighting a new attack vector targeting AI-driven development tools. This demonstrates how AI agents can be tricked through file-based social engineering, combining traditional supply chain tactics with AI automation.
