# MAL-2026-13111: Malicious code in bpm-foundation-husky (npm)

## What is MAL-2026-13111?

MAL-2026-13111 is a malicious package in bpm-foundation-husky, published on 5 Aug 2026. 

### Official description

index.js unconditionally requires _runtime.js on module load. _runtime.js selects a platform-specific endpoint (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), fetches a binary over HTTPS from one of four hardcoded *.workers.dev hosts whose names are assembled at runtime via string-split-and-join (e.g. ["oob-worker.cf99-9b3.worke","rs.de","v"].join("")), with a DNS TXT-record fallback channel to *.dl.wel1.ru that pulls a base64-encoded payload in chunks and reassembles it. The fetched bytes are written to /var/tmp/.cache_<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows, chmod 0755'd, and spawned detached via /bin/sh -c or cmd.exe. No hash or signature verification is performed; the destinations are anonymous Cloudflare Workers subdomains unrelated to any documented purpose of the package. A once-per-~6h marker file limits re-execution to evade detection. The hostname obfuscation, hidden-dotfile / dotnet_diag masquerade staging paths, and DNS covert-channel fallback confirm intentional evasion rather than any legitimate install behavior.

## What should I do about MAL-2026-13111?
