🛡️ MAL-2026-12307 — twork-products-taiga2-products-timeline

Malicious code in twork-products-taiga2-products-timeline (npm)

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.
