Which versions of bigops-products are malicious?

The following npm versions of bigops-products are flagged malicious: 35.7.4. Treat any of these as compromised.

How do I remediate bigops-products if I installed it?

Remove bigops-products 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 bigops-products — how do I know if it already compromised me?

If bigops-products 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.

Yes — bigops-products is associated with the IN-MAL-2026-015762 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 bigops-products across my projects, lockfiles, and CI pipelines?

What this malware does

On require() of bigops-products, init.js downloads a platform-specific binary from Cloudflare Workers hosts whose names are assembled at runtime from string fragments (oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS-TXT covert-channel fallback that reconstructs a base64 payload from numbered subdomains of *.dl.wel1.ru (sdk/ext/pkg/net.dl.wel1.ru). The fetched binary is written to /tmp or %TEMP% under a cover name (.cache<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 755, then spawned detached via spawn("/bin/sh",["-c", path+" &"],{detached:true,stdio:"ignore"}).unref() (or spawn("cmd",...) on Windows). A marker file.analytics_state and env-var opt-outs (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK) provide telemetry cover. Destination hostnames are constructed via array.join to defeat static string scans.
