An AI agent runs with your credentials and acts before you can stop it. Nine incidents show what that costs. Six controls limit the damage: sandbox the agent, scope its credentials, lock its configuration, log every call, scan the workspace first, and deny by default.
The GhostAction supply chain campaign hit 772 public GitHub repositories between Aug. 31 and Sept. 30, 2026, targeting 2,577 secrets. Between Oct 8-9 a new burst hit 30k more, and this time the workflows ran.
Attackers dumped everything they harvested from LiteLLM builds during a 40-minute window in March. Here is what is inside and what it says about where secrets live.
Millions of fake commits are flooding GitHub's public feed. We followed the trail to a rebranded gambling site hiding behind a defunct lottery brand.
After the CISA GitHub leak, the agency published a candid incident postmortem. Here are six lessons security teams should copy, from secrets scanning to key rotation.
We found 62 live PyPI tokens leaking on public sources, enough to push malicious code to 125 packages with 25,000 monthly downloads. We reported them to PyPI, which revoked every one. Here's how we decoded the macaroons and checked which still worked.
On May 14, GitGuardian found a public GitHub repository called "Private-CISA" — 844 MB of plain-text passwords, AWS tokens, and Entra ID SAML certificates belonging to CISA, exposed since November 2025. Some credentials were still valid. CISA pulled it offline within 26 hours.
A self-replicating worm is actively compromising packages with 3M+ weekly downloads, hijacking tokens from CI/CD pipelines, and bypassing trusted publishing protections.
LLMs leave statistical fingerprints in the passwords they generate. We built a 100-year-old model to find them and detected 28,000 in the wild.
