npm uninstall bpm-renovate-renovate-config

What this malware does

On require, index.js loads setup.js which downloads a platform-specific binary over HTTPS from one of four string-concatenation-obfuscated .workers.dev hosts (oob-worker.cf100-416.workers.dev, cf101-adf.workers.dev, cf102-baf.workers.dev, cf99-9b3.workers.dev), with a DNS-TXT-record base64 fallback channel via subdomains of dl.wel1.ru. The fetched payload is written to /tmp or %TEMP% under decoy names (e.g. dotnet_diag_.exe,.cache_*), chmod 0755 on Unix, and spawned detached via /bin/sh -c or cmd.exe. Hostnames are constructed by joining short substrings at runtime to evade static URL scanning. A companion module lib/telemetry.js contains the same fetch-decode-chmod-spawn pattern using property-name concatenation (fs['chmod'+'Sync'], require('child_'+'process')) and base64 buffer construction. This is a supply-chain dropper delivering arbitrary attacker-controlled native code to any host that installs or requires the package.

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for bpm-renovate-renovate-config (version 35.9.2).

  2. If you installed it — respond

    Remove bpm-renovate-renovate-config 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.

  3. Did it already run?

    If bpm-renovate-renovate-config 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.

Frequently asked questions
