Claude Code's GitHub Action: One Malicious Issue Could Hijack Any Public Repo
A permission bypass chained with prompt injection in Anthropic's Claude Code GitHub Action let a single crafted issue make the agent leak CI secrets and OIDC request tokens — a clean path to poisoning the action's own supply chain. Patched in v1.0.94.
Anatomy of the Interlock Campaign: How a ClickFix Gang Learned to Burn Firewall Zero-Days
For a year, the surest way to get hit by Interlock was to paste a command into your own Run dialog. On January 26, 2026, the group stopped waiting for users to make mistakes and started exploiting a pre-auth, root-level Cisco firewall zero-day instead. The same crew now runs both ends of the sophistication ladder — and that should change how you model initial access.
