bpm-foundation-huskynpm
Advisory published Updated
bpm-foundation-husky is a confirmed malicious npm package (MAL-2026-13111) that executes malicious code on install (malicious version 35.7.6). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bpm-foundation-husky (npm)
What this malware does
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.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for bpm-foundation-husky (version 35.7.6).
If you installed it — respond
Remove bpm-foundation-husky from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If bpm-foundation-husky was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks bpm-foundation-husky-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
