AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote payload execution with concealed delivery infrastructure and no usable integrity check. It is unrelated to the exposed payments API.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of index.js.
Impact
Arbitrary attacker-controlled code executes under the importing user's privileges.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
The main entrypoint suppresses errors while requiring _bootstrap.js. Its init function downloads a platform-specific payload from concealed Workers hosts, or reconstructs one from DNS TXT records, writes it to a temporary path, grants execute permission on Unix, and launches it detached through /bin/sh or cmd.exe. The temp marker only rate-limits execution; it is not user consent or verification.
AI rationale
This is concrete import-time remote payload execution with concealed delivery infrastructure and no usable integrity check. It is unrelated to the exposed payments API.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap.js on every package import.
- _bootstrap.js downloads platform binaries from obfuscated worker hosts.
- Downloaded bytes are written to a temp file, made executable, and detached via shell/cmd.
- DNS TXT fallback supplies another base64 payload; no actual integrity verification occurs.
Evidence against
- package.json has no lifecycle scripts.
- Public Payments API is minimal, but it does not prevent import-time bootstrap execution.
