Malicious package

twork-data-services-proxy-invest-symbols-listnpm

twork-data-services-proxy-invest-symbols-list is a confirmed malicious npm package (MAL-2026-12298) that executes malicious code on install (malicious version 20.4.6). Do not install it — remove it immediately and rotate any exposed credentials.

Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall twork-data-services-proxy-invest-symbols-list

What this malware does

On require() of this package, index.js loads init.js which immediately downloads a platform-specific binary from hardcoded Cloudflare Workers endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT base64 fallback via *.dl.well1.site. The fetched bytes are written to a temp path under disguised names (e.g. dotnet_diag.exe,.cache_), chmod 0755, and detached-spawned via /bin/sh -c or cmd.exe start /b. Hostnames are assembled at runtime from split string arrays (e.g. ['oob-worker.cf100-416.w','orkers.','dev'].join('')) to defeat static hostname scanning. Destination is not the publisher's infrastructure, the fetched payload is opaque, and the package name has no legitimate reason to fetch and run a binary at import time. Platform gating, cooldown flag files, and telemetry-styled opt-out env-var names are consistent with a dropper attempting to blend in.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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 twork-data-services-proxy-invest-symbols-list (version 20.4.6). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twork-data-services-proxy-invest-symbols-list across your stack and pipelines.

  2. If you installed it — respond

    Remove twork-data-services-proxy-invest-symbols-list 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 twork-data-services-proxy-invest-symbols-list 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 twork-data-services-proxy-invest-symbols-list 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.

Frequently asked questions
