What this malware does

On require('bigops-products-bnpl'), index.js loads runtime.js, which selects a platform-specific endpoint and downloads an opaque binary from one of four hardcoded Cloudflare Workers hosts (oob-worker.cf101-.workers.dev, oob-worker.cf102-.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT base64 fallback via *.dl.wel1.ru. The downloaded bytes are written under a disguised name (e.g. dotnet_diag.exe,.cache_) to /tmp or %TEMP%, chmod'd 0o755, and spawned detached via /bin/sh -c or cmd.exe. Destination hostnames are assembled from split string fragments joined with.join('') to evade static analysis, and a.analytics_state marker file is written to avoid re-running. No hash or signature verification is performed, the hosts are anonymous mutable Cloudflare Workers unrelated to the package's stated 'bnpl wrapper' purpose, and comments frame the code as 'telemetry'/'CDN'/'analytics' as cover. The result is arbitrary attacker-controlled code execution on the installer's machine as a side effect of loading the package.

Detection & response playbook

Malicious package
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for bigops-products-bnpl (version 35.2.9). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bigops-products-bnpl across your stack and pipelines.

  2. If you installed it — respond

    Remove bigops-products-bnpl 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 bigops-products-bnpl was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks bigops-products-bnpl before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
