@lystech/core@3.0.103
Lystech Core contains essentials for lystech apps
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe active postinstall hook automatically writes a consumer CI workflow, creating a real install-time configuration risk. The inspected code does not establish credential exfiltration or another block-eligible attack, so warn rather than block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package in a project that declares @lystech/core, unless the skip conditions apply.
Impact
This changes the consumer's CI configuration and causes repository metadata to be sent to the package registry when the workflow runs. No credential theft or broader malicious chain was established.
Mechanism
The postinstall hook writes a workflow file when that path does not already exist; the workflow later performs registry synchronization on pushes or manual dispatch.
AI rationale
The active postinstall hook automatically writes a consumer CI workflow, creating a real install-time configuration risk. The inspected code does not establish credential exfiltration or another block-eligible attack, so warn rather than block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package manifest runs bin/postinstall.cjs automatically after installation.
- The hook checks for @lystech/core in the consumer manifest, then creates a GitHub Actions workflow if one is absent.
- The generated workflow registers repository metadata with the package registry endpoint.
Evidence against
- The hook skips when run in this package itself and supports an SKIP_LYSTECH_SETUP environment guard.
- The reviewed bundled endpoint is a product API; the inspected source did not establish credential collection or exfiltration.
