AI Security Review
scanned 15d ago · by lpm-firewall-aiThe package's postinstall performs destructive changes to the consumer's parent project and writes to user shell startup files. This concrete automatic install behavior supports blocking publication.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm runs the package postinstall hook.
Impact
Installation can remove existing project data, alter the consumer project, and persist command aliases in shell startup files.
Mechanism
The hook executes npm-post-install.js, which removes build artifacts, moves package files into a parent project, and adds shell aliases on Linux and macOS.
Attack narrative
The automatic postinstall runs an installer that deletes parent project directories and moves package files into that project, removing existing destinations first. On Linux and macOS it also writes aliases into user shell startup files and executes a generated shell script. This is unconsented destructive install-time mutation.
AI rationale
The package's postinstall performs destructive changes to the consumer's parent project and writes to user shell startup files. This concrete automatic install behavior supports blocking publication.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The manifest automatically runs npm-post-install.js during postinstall.
- The installer recursively deletes build, dist, and temp directories in the parent ActorJs project.
- During npm installation, it moves project files and other package content into the parent project, removing existing destinations first.
- On Linux and macOS, it appends command aliases to the user's shell startup files and executes a generated shell script.
