Summary
Malicious code in bpm-foundation-feature-flags (npm)

Source: amazon-inspector (4736a188169920cb89859c87cc5d53ed9a51db4f368f15546f2b999a6ec12045)

On require() of bpm-foundation-feature-flags, index.js loads init.js which downloads a platform-specific native binary from obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT fallback channel to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru that reconstructs base64-encoded binary bytes from TXT records. The downloaded bytes are written to /tmp or %TEMP% under disguised names (.cache<hex>, dotnetdiag<hex>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe /c start /b. Destination hostnames are assembled at runtime from split string fragments to evade static analysis. The behavior is framed as opt-out 'telemetry/analytics' (DISABLETELEMETRY, ANALYTICSOPTOUT, DONOTTRACK env checks and a /tmp/.analyticsstate freshness marker), but the fetched payload is an opaque native executable unrelated to the declared feature-flag purpose. This yields remote code execution on the installer's host at import time.
