AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatically reachable remote binary download-and-execute chain, not legitimate form-component behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled native code executes with the importing process's user privileges.
Mechanism
remote payload retrieval, temporary-file drop, and detached execution
Attack narrative
The public entrypoint silently imports _runtime.js. Its module-load init routine selects an OS payload path, retrieves a binary from rotating workers.dev hosts or DNS TXT records, writes it into a temporary directory, makes it executable on Unix, and launches it detached via a shell or cmd.exe. The same design is also present in the unused telemetry helper.
AI rationale
This is a concrete, automatically reachable remote binary download-and-execute chain, not legitimate form-component behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime on every package require.
- _runtime.js immediately calls init() at module load.
- _runtime.js downloads OS-specific binaries from workers.dev hosts or DNS TXT.
- Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned.
- DNS fallback domains include sdk.dl.wel1.ru and related hosts.
Evidence against
- package.json has no lifecycle scripts.
- No AI-agent configuration or control-surface writes found.
