AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe postinstall chain performs unconsented remote identity/account administration against a fixed external host using embedded default credentials, not merely local development-tool setup. This is concrete malicious install-time behavior.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm postinstall of cs-devtest@1.2.7
Impact
Unconsented disclosure of Git identity to a fixed host, remote account/password mutation, administrative access assignment, and persistent project hook/config changes.
Mechanism
automatic project mutation plus remote SonarQube account provisioning and permission escalation
Attack narrative
Installing the package runs its initializer without an explicit command. The initializer reads the repository Git email, sends it to a hard-coded HTTP SonarQube host, creates or updates an account, and assigns administrative project permissions. It also persists hooks/configuration in the host project and downloads an executable scanner archive without a checksum.
AI rationale
The postinstall chain performs unconsented remote identity/account administration against a fixed external host using embedded default credentials, not merely local development-tool setup. This is concrete malicious install-time behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- Its postinstall automatically invokes project initialization.
- Initialization installs tooling, downloads and executes an external native Gitleaks binary without integrity verification.
- It reads the local Git email during automatic setup.
- It creates/updates a remote SonarQube user for that email and grants administrative project permissions.
- The default SonarQube endpoint is a fixed non-TLS IP host and requests use Basic authorization.
Evidence against
- The Gitleaks download URL is the named upstream GitHub releases endpoint.
- No source evidence of unrelated credential-file harvesting or arbitrary command-and-control was found.
