AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time staged payload execution, not package-aligned configuration behavior. Lack of an npm lifecycle hook does not mitigate execution on normal require/import.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import/require of trapp-configuration
Impact
Arbitrary remote code execution as the importing user.
Mechanism
import-time remote payload download, drop, chmod, and detached execution
Attack narrative
The public entrypoint silently loads _adapter.js. At import time it fetches an opaque platform-specific binary from obfuscated worker hosts, falling back to DNS TXT payload retrieval; it writes the bytes under a temporary hidden/random filename, sets executable permissions on non-Windows systems, and starts it detached through /bin/sh or cmd.exe.
AI rationale
This is concrete import-time staged payload execution, not package-aligned configuration behavior. Lack of an npm lifecycle hook does not mitigate execution on normal require/import.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js on every package import.
- _adapter.js immediately calls run() at module load.
- _adapter.js downloads a platform payload over HTTPS or DNS TXT.
- Downloaded bytes are written, made executable, and detached-spawned via shell/cmd.
- Endpoints are obfuscated and unrelated to the stated config-reader purpose.
Evidence against
- package.json has no lifecycle scripts.
- index.js otherwise implements a conventional local environment/config reader.
- No credential or project-file exfiltration was found in the inspected entrypoint chain.
