@lystech/core@3.0.123
Lystech Core contains essentials for lystech apps
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall automatically modifies the consumer project by creating a GitHub Actions workflow, so the installation side effect warrants a warning. The registry synchronization and bundled telemetry use Lystech endpoints, and the inspected source does not establish credential exfiltration or another block-eligible attack.
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
The package postinstall runs in a consumer project that declares @lystech/core and lacks the workflow file.
Impact
The consumer project is modified automatically and later sends repository metadata to the package vendor. No credential theft or other concrete attack was established.
Mechanism
The postinstall writes .github/workflows/sync-package-registry.yml; the generated workflow runs on pushes to master or main and sends repository metadata to the registry.
AI rationale
The postinstall automatically modifies the consumer project by creating a GitHub Actions workflow, so the installation side effect warrants a warning. The registry synchronization and bundled telemetry use Lystech endpoints, and the inspected source does not establish credential exfiltration or another block-eligible attack.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs bin/postinstall.cjs automatically after installation.
- The postinstall checks whether the consumer declares @lystech/core, then writes a GitHub Actions workflow into the consumer project.
- The generated workflow runs on pushes to master or main and sends repository metadata to the package registry endpoint.
- The bundled client also sends batched client events, a session identifier, and an email value to its configured Lystech API endpoint.
Evidence against
- The postinstall skips when SKIP_LYSTECH_SETUP=true and does not overwrite an existing workflow.
- The bundled API endpoint is the package’s Lystech service; the inspected telemetry code does not show an unrestricted operator-controlled destination.
