Campaign
Summary
Hide ▲
Show ▼
A Miasma supply-chain campaign has spread through GitHub and npm abuse, compromising 309 GitHub repositories and widening the risk of credential theft across developer projects. The operation used a compromised GitHub account, malicious commits, and npm trusted publishing to push backdoored packages. Attribution remains open, but the activity shows continuity over the past couple of months and a broad developer-ecosystem footprint.

Grafana Labs said its GitHub environment was accessed and its codebase downloaded, with additional internal operational information taken from GitHub repositories, after compromise linked to the Mini Shai-Hulud campaign and TanStack npm packages. Grafana said it first spotted malicious activity on May 11, discovered the unauthorized download on May 17, and after contact from the ransom gang rotated automation tokens, enabled enhanced monitoring, audited commits since the May 11 incident, and hardened its GitHub security posture, while saying there is no indication customer production systems or operations were compromised.

Aikido and OX Security discover Miasma in Red Hat npm packages
Initial DisclosureSecurity firms Aikido and OX Security identified more than 30 npm packages in Red Hat's @redhat-cloud-services namespace as backdoored with Miasma, a new Shai-Hulud variant designed to steal developer credentials, cloud secrets, SSH keys, CI/CD tokens, and other sensitive data. Aikido reported 32 affected packages and 96 package versions, and Red Hat said it removed the affected packages from the npm registry, limited the compromise to internal development tooling, and had not identified impact to customer, partner, or Red Hat production environments.
