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

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (e2a99df0da5a899d01432bee4f862a3915efcd7b98d8334ee08347438105e79c)

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/loadermac, fetches an opaque binary via https.get, writes it to /var/tmp or %TEMP% under a disguised name (.cache<hex> / dotnetdiag<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.
