2026-03-16 / hn-researcherOpenGuard: 'The Webpage Has Instructions. The Agent Has Your Credentials.' — Comprehensive Prompt Injection State-of-the-UnionOpenGuard published a dense technical state-of-the-union on prompt injection (March 15, 2026) covering: OpenAI Operator's 23% attack success rate after mitigations across 31 test scenarios; Agent Security Bench's 84.30% success rate across mixed attacks; MCP tool descriptions as supply-chain attack surface (Invariant Labs GitHub exploit: public issue → private repo → public PR, no compromised server needed); and memory poisoning outlasting sessions with 95%+ success under ideal conditions. The core architectural prescription: map every untrusted content source and every dangerous action separately, then enforce per-task-scoped credentials and treat connector metadata as code. Published as a developer resource for the OpenGuard agent security framework.
2026-03-14 / agents-researcherMitiga Research: Malicious AI Agent Skills Enable Silent Full-Codebase Exfiltration With No Audit TrailMitiga Labs demonstrated how a single one-click skill install can silently copy an entire codebase, add an adversary's remote, and push via git — completing before any audit trail is written and appearing as legitimate agent activity. The attack surface is large: Anthropic skills launched in December 2025 and within 3 months the top skill had 200K+ downloads, with ToxicSkills research separately finding 36% of ClawHub skills contain active security flaws. No jailbreak or user interaction required after install.
