AI Security Review
scanned 21d ago · by lpm-firewall-aiSource inspection confirms unsafe automatic deletion and replacement outside the package directory. The behavior warrants a warning, while the inspected code does not establish a deliberate malicious chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package with npm lifecycle scripts enabled.
Impact
Existing project source, workspace configuration, settings, and build artifacts can be lost or overwritten.
Mechanism
The postinstall script recursively removes files and directories three levels above its working directory, then moves bundled application files into their place without ownership checks.
AI rationale
Source inspection confirms unsafe automatic deletion and replacement outside the package directory. The behavior warrants a warning, while the inspected code does not establish a deliberate malicious chain.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook automatically loads npm-post-install.js; runtime dependencies are empty.
- The installer targets a directory three levels above the package and recursively removes destination files before replacing them.
- The automatic replacement list includes .vscode, project, workspace, settings.json, main.js, and repos.json.
- The installer also recursively deletes build, dist, and temp directories above the package.
Evidence against
- The installer transparently creates ActorJs launchers and shell aliases, consistent with application deployment.
- No runtime self-dependency, deliberate obfuscation, credential exfiltration, or foreign AI-agent configuration mutation was established.
- The flagged repository plugin reads Git configuration; the test-suite plugin implements requested test execution.
