BufferZoneCorp sleeper attack on RubyGems + Go modules

Socket disclosed a coordinated sleeper-package campaign attributed to the GitHub org BufferZoneCorp (and RubyGems user knot-theory). Initially-clean Ruby gems and Go modules were updated to malicious versions. The Ruby side harvests env vars, SSH keys, AWS secrets, .npmrc, .netrc, GitHub CLI config, and RubyGems credentials; the Go side tampers with GitHub Actions workflows, injects fake executables, and adds SSH persistence via authorized_keys. First confirmed 2026 RubyGems + Go module supply-chain campaign.

What to do if you installed one of these

Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.
