Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall warp-drive-internal-tooling

What this malware does

[email protected] declares a preinstall hook that runs index.js, which on Windows spawns a hidden-window PowerShell process (powershell -WindowStyle Hidden) that downloads a zip archive from the anonymous file host files.catbox.moe (https://files.catbox.moe/5khq55.zip), extracts it into %TEMP%, and launches Verification_Tool.exe via Start-Process. The remote host is an unauthenticated throwaway file service unrelated to the package's stated purpose, the download is unpinned and unverified (no hash, no signature), and the fetched binary is opaque. Because npm auto-runs preinstall on every npm install, this results in unattended execution of an attacker-controlled Windows executable on the installer's machine, with concealment (hidden PowerShell window, staging under %TEMP% with a benign 'Verification_Tool' filename) consistent with a dropper rather than a legitimate build step.

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for warp-drive-internal-tooling (version 99.9.9).

  2. If you installed it — respond

    Remove warp-drive-internal-tooling 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 warp-drive-internal-tooling 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
