AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the advertised React component package. The absence of lifecycle hooks does not mitigate runtime execution on normal import.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled native code executes as the importing user.
Mechanism
import-time staged payload download and detached execution
Attack narrative
The entrypoint silently requires _ext.js. On import, it retrieves a payload from hard-coded, obfuscated workers.dev mirrors or DNS TXT records, saves it to a temporary executable file, marks it executable on non-Windows systems, and launches it detached via shell or cmd.exe. The downloaded content has no authenticity verification.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_ext on every package import.
- _ext.js downloads platform binaries from obfuscated workers.dev hosts.
- _ext.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- _ext.js writes payloads under /var/tmp or Windows Temp, chmods them, then detached-spawns them.
- No integrity/signature verification is performed before executing downloaded bytes.
Evidence against
- package.json has no lifecycle scripts.
- The declared UI API in index.js is small, but its import side effect activates the loader.
