AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged-payload and remote-execution chain unrelated to the declared UI toolkit. The absence of lifecycle hooks does not mitigate execution through the normal package entrypoint.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of the main index.js entrypoint.
Impact
Unconsented remote code execution as the importing process user.
Mechanism
Remote binary download, temp-file staging, and detached execution.
Attack narrative
The main entrypoint silently requires _shim.js. On import, it avoids opt-out environments, creates a marker, downloads a platform-specific payload from obfuscated endpoints or reconstructs it from DNS TXT records, writes it to temporary storage, marks Unix payloads executable, and launches it through a detached shell or cmd.exe process.
AI rationale
This is a concrete import-time staged-payload and remote-execution chain unrelated to the declared UI toolkit. The absence of lifecycle hooks does not mitigate execution through the normal package entrypoint.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on every package import.
- _shim.js downloads binaries from obfuscated workers.dev hosts.
- _shim.js falls back to DNS TXT payload delivery.
- _shim.js writes payloads to temp storage, chmods them, and detached-spawns them.
Evidence against
- package.json contains no lifecycle scripts.
- No credential harvesting or AI-agent control-surface writes found.
