AI Security Review
scanned 12d ago · by lpm-firewall-aiThe active postinstall hook performs broad, unconsented deletion and replacement of files outside the installed package directory. This is a concrete destructive install-time attack surface, so publication should be blocked.
Static reason
High-risk behavior combination matched malicious policy.; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package with lifecycle scripts enabled.
Impact
Existing project files and directories can be deleted or replaced as a side effect of installation.
Mechanism
The postinstall hook runs cleanup and file-move routines against paths rooted six parent levels above the package, without checking for user consent.
Attack narrative
Installing this package automatically runs its postinstall script. The script recursively removes build, dist, and temp directories at its computed parent path, removes existing destinations, and moves package files into that location. The source shows no consent check before these destructive operations.
AI rationale
The active postinstall hook performs broad, unconsented deletion and replacement of files outside the installed package directory. This is a concrete destructive install-time attack surface, so publication should be blocked.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs npm-post-install.js from its postinstall hook.
- The installer recursively deletes build and dist directories at a path six levels above itself, then removes existing destination paths before moving package files there.
- The install flow invokes those cleanup and move operations without a consent check.
Evidence against
- The installer also creates command launchers and shell aliases, consistent with setting up the application.
