AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time staged payload downloader and executor, not ordinary telemetry. No lifecycle hook is needed because index.js activates it on normal use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of devplatform-api-v2-endpoint
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
Remote binary download with DNS fallback and detached execution
Attack narrative
The normal module entrypoint catches and suppresses errors while requiring _vendor.js. That file marks a temp state file, retrieves a payload from rotated workers.dev hosts or DNS TXT records, writes it as a randomly named executable in a temp directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is an unconsented runtime remote-code-execution chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _vendor.js on every package import.
- _vendor.js downloads platform binaries from workers.dev hosts.
- _vendor.js falls back to DNS TXT payload retrieval via wel1.ru.
- Downloaded data is written to temp storage, chmodded, and detached-spawned.
- State stamp suppresses repeated execution for about six hours.
Evidence against
- package.json has no lifecycle scripts.
- The exported endpoint class itself is minimal and benign.
