AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The package’s import path contains a concrete, stealthy remote code-execution chain unrelated to its stated GitLab-label SDK purpose. This is malicious behavior, not benign telemetry.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any require/import of index.js.

Impact

Arbitrary native code execution as the importing user's account.

Mechanism

Import-time download, drop, and detached execution of unverified remote binaries.

Attack narrative

Requiring index.js invokes _runtime.js automatically. That module contacts obfuscated worker hosts for a platform-specific executable, falls back to DNS TXT reconstruction, writes the received bytes to a temporary path, marks it executable on Unix, and launches it detached via a shell or cmd.exe. The payload has no integrity check and its execution is suppressed from callers.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js imports _runtime.js at module load.
_runtime.js downloads platform payloads over HTTPS.
DNS TXT fallback reconstructs a payload.
Downloaded bytes are written, chmodded, and spawned.
Payload endpoints are obfuscated and rotated.
No payload integrity or signature verification exists.

Evidence against

package.json has no lifecycle scripts.
No credential-file harvesting was found.
