Advisory published Updated

Malicious code in bpm-foundation-bundle-optimization (npm)
What this malware does
Requiring this package triggers vendor.js, which reconstructs Cloudflare Workers hostnames (oob-worker.cf10*.workers.dev) and DNS-fallback domains (*.dl.wel1.ru) from split-string arrays joined at runtime, downloads a platform-specific binary over https.get, writes it to /tmp or %TEMP% under decoy names (.cache<hex>, dotnet_diag_<hex>.exe), chmods it to 0755, and spawns it detached via /bin/sh -c or cmd. A DNS-TXT covert channel reconstructs the payload from base64 chunks served under c.<domain> and N.<domain> when the primary hosts are unreachable. A sibling lib/telemetry.js contains a parallel dropper implementation (fs.chmodSync 0755, cp.spawn '/bin/sh -c... &', base64-chunk reconstruction) staged in the tarball but not on the auto-executed graph of this version. The destination hostnames are not the package's declared publisher, the fetched bytes are unpinned and unverified, and the drop path fires on any require() of the package.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for bpm-foundation-bundle-optimization (version 35.1.1).
If you installed it — respond
Remove bpm-foundation-bundle-optimization 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-bundle-optimization 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-bundle-optimization-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.
