AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe entrypoint reaches an unsigned remote payload downloader/executor during normal import, unrelated to the stated React-component purpose. The unused telemetry module contains a similar configurable loader pattern but is not needed to establish the attack.
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 can run with the importing process's privileges.
Mechanism
Remote binary download, drop, chmod, and detached execution.
Attack narrative
On package import, index.js requires _shim.js. The shim fingerprints the OS, retrieves a platform-specific binary from obfuscated Workers hosts, or reconstructs one from DNS TXT records, writes it under a temporary filename, marks it executable on Unix, and launches it detached via shell or cmd.exe. This is a concrete remote-code-execution chain without integrity verification.

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 platform-specific binary payloads over HTTPS or DNS TXT.
- _shim.js writes payloads to temp storage, chmods on Unix, then detached-spawns them.
- Remote hosts and DNS fallback domains are obfuscated by string concatenation.
- No checksum, signature, or user action gates remote binary execution.
Evidence against
- package.json has no lifecycle hooks.
- No credential harvesting or package-file modification was found.
