Radware found 2,281 hidden GitHub notes aimed at coding agents, 47 of them attacks
Published Nov 5, Radware scanned about 145 million GitHub issues, pull requests, comments, and READMEs and found 2,281 hidden, AI-directed instructions (about 16 per million), a rate that more than doubled from June to September. Only 47 were attacks—more than half targeting a project's own triage, review, or CI bot—while two-thirds were projects leaving notes for their own agents, which anyone can forge unless the bot checks who wrote them.
