Malicious code in warp-drive-internal-tooling (npm)
--- _-= Per source details.

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.
