AI coding agents hijacked using AGENTS.md file in Downloads folder

Researchers discovered a malicious AGENTS markdown file placed in a customer's Downloads folder that deceived an artificial intelligence (AI) coding agent into installing a malicious npm package. The attack exploited how AI agents read and execute instructions from files in accessible directories.

Why it matters: Development teams using AI coding agents are exposed to local file-based prompt injection attacks that can lead to supply chain compromise through rogue package installation.
