AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, unconsented import-time remote payload execution, unrelated to the advertised UI toolkit. Lack of an npm lifecycle hook does not mitigate execution on ordinary package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of the package main entrypoint.
Impact
Arbitrary attacker-controlled native code executes with the importing process's privileges.
Mechanism
remote binary download/DNS payload retrieval followed by detached execution
Attack narrative
The main entrypoint silently imports _bootstrap.js. At import time it selects a platform payload, downloads it from rotating worker hosts or reconstructs it from DNS TXT records, stores it in a temporary executable file, and launches it detached through cmd.exe or /bin/sh. The payload is opaque and remote-controlled.
AI rationale
This is concrete, unconsented import-time remote payload execution, unrelated to the advertised UI toolkit. Lack of an npm lifecycle hook does not mitigate execution on ordinary package 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 _bootstrap.js on every package import.
- _bootstrap.js downloads platform payloads from three workers.dev hosts.
- _bootstrap.js falls back to DNS TXT payload retrieval from dl.wel1.ru domains.
- Downloaded bytes are written to a temp file, made executable, and detached-spawned.
- Execution is hidden and errors are suppressed; a temp marker rate-limits repeats.
Evidence against
- package.json has no lifecycle scripts.
- Public UI API in index.js is otherwise minimal.
