## What is MAL-2026-12307?

MAL-2026-12307 is a malicious package in twork-products-taiga2-products-timeline, published on 5 Aug 2026. 

### Official description

On require() of the package, index.js exports a no-op class and unconditionally loads _bridge.js. _bridge.js reconstructs command-and-control hostnames via split-string concatenation (e.g. oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, with a DNS TXT fallback channel at *.dl.well1.site), selects a platform-specific endpoint under /pkg/package, /pkg/package-arm64, /pkg/package.exe, or /pkg/loader_mac, fetches an opaque binary via https.get, writes it to /var/tmp or %TEMP% under a disguised name (.cache_<hex> / dotnet_diag_<hex>.exe), chmods it 0755, and spawns it detached via /bin/sh -c '<path> &' or cmd.exe start /b with stdio ignored. No hash or signature verification is performed. The endpoints are anonymous, mutable Cloudflare Workers hosts unrelated to the package's advertised 'timeline provider' purpose; the advertised library API is a cover for the dropper path.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-12307?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
