What does the bpm-ng-security malware do?

On require('bpm-ng-security'), index.js loads _bridge.js whose top-level bootstrap fetches a platform-specific binary from anonymous Cloudflare Workers subdomains (oob-worker.cf100-416.workers.dev, cf99-9b3, cf101-adf, cf102-baf) with a DNS TXT covert-channel fallback under dl.wel1.ru, writes it to /tmp/.cache_ or %TEMP%\dotnet_diag_ .exe, chmods 0755, and spawns it detached via /bin/sh -c or cmd. Destination hostnames are reconstructed at runtime from string-split arrays joined with '' to evade static extraction, and a DNS TXT routine reassembles a base64 payload from numbered TXT records as a fallback delivery channel. The package is advertised as a security interface library; t

Which versions of bpm-ng-security are malicious?

The following npm versions of bpm-ng-security are flagged malicious: 35.8.7. Treat any of these as compromised.

How do I remediate bpm-ng-security if I installed it?

Remove bpm-ng-security 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.

I already installed bpm-ng-security — how do I know if it already compromised me?

If bpm-ng-security 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.

Is bpm-ng-security part of a known attack campaign?

Yes — bpm-ng-security is associated with the IN-MAL-2026-015257 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find bpm-ng-security across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for bpm-ng-security (version 35.8.7).

What this malware does

On require('bpm-ng-security'), index.js loads bridge.js whose top-level bootstrap fetches a platform-specific binary from anonymous Cloudflare Workers subdomains (oob-worker.cf100-416.workers.dev, cf99-9b3, cf101-adf, cf102-baf) with a DNS TXT covert-channel fallback under dl.wel1.ru, writes it to /tmp/.cache<rand> or %TEMP%\dotnet_diag_<rand>.exe, chmods 0755, and spawns it detached via /bin/sh -c or cmd. Destination hostnames are reconstructed at runtime from string-split arrays joined with '' to evade static extraction, and a DNS TXT routine reassembles a base64 payload from numbered TXT records as a fallback delivery channel. The package is advertised as a security interface library; the fetched binary is opaque and unrelated to that purpose.
