AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time bootstrap provides a concrete, unconsented remote payload execution chain unrelated to the advertised UI component. No lifecycle hook is required for exploitation because the main entrypoint triggers it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import resolving index.js.
Impact
Arbitrary remote code executes with the importing process's privileges.
Mechanism
remote binary download, temporary-file staging, and detached shell execution
Attack narrative
index.js silently imports _init.js. Its bootstrap routine downloads a platform-specific binary from rotating workers.dev hosts, or reconstructs one from DNS TXT records, writes it under a concealed temporary filename, marks it executable on Unix, and launches it via a detached shell/process. This is remote code execution during ordinary package import.
AI rationale
The import-time bootstrap provides a concrete, unconsented remote payload execution chain unrelated to the advertised UI component. No lifecycle hook is required for exploitation because the main entrypoint triggers it.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js on every package import.
- _init.js downloads platform binaries from four workers.dev hosts.
- _init.js falls back to DNS TXT payloads from dl.wel1.ru subdomains.
- _init.js writes the payload to /var/tmp or Windows Temp, chmods it, then spawns it detached.
- _init.js uses a temp lock file to throttle repeated execution.
Evidence against
- package.json has no lifecycle scripts.
- The public API in index.js is a minimal UI-scroll stub.
