AI Security Review
scanned 12d ago · by lpm-firewall-aiThe automatic install hook performs destructive and broad filesystem changes outside its package directory, including deleting existing project paths before moving package contents into place. This is a concrete 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 npm, which invokes its postinstall hook.
Impact
Existing project data can be deleted or replaced, and shell startup configuration can be changed without a separate user action.
Mechanism
The hook executes filesystem deletion and move operations against ancestor paths, and on Linux or macOS executes a generated shell script that appends command aliases to shell profiles.
Attack narrative
During npm installation, the postinstall hook runs automatically. It removes existing ancestor project directories and destinations before moving package files into them; on Linux or macOS it also runs a generated script that can append aliases to shell startup files.
AI rationale
The automatic install hook performs destructive and broad filesystem changes outside its package directory, including deleting existing project paths before moving package contents into place. This is a concrete 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 automatically during postinstall.
- The hook deletes build and dist directories three levels above the package, and also removes temp.
- It removes destination files before moving package contents into the ancestor project, including .vscode, project, workspace, and settings.json.
- On Linux and macOS, it runs a generated shell script from six directory levels above the package; that script appends aliases to the user's shell profile.
