AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Direct source inspection confirms import-time remote payload download and execution. The benign-looking public API and absence of lifecycle hooks do not mitigate this reachable malicious behavior.

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, unless telemetry opt-out environment variables are set.

Impact

Arbitrary remote code execution as the importing process user.

Mechanism

Remote binary download, DNS fallback, temp-file drop, and detached shell execution.

Attack narrative

The package entrypoint silently loads _polyfill.js. On import, it retrieves a platform-specific payload from obfuscated worker hosts or DNS TXT records, drops it in temporary storage, marks it executable on Unix, and starts it through a detached shell or cmd.exe. This is a concrete remote-code-execution chain with no user invocation or payload verification.

AI rationale

Direct source inspection confirms import-time remote payload download and execution. The benign-looking public API and absence of lifecycle hooks do not mitigate this reachable malicious behavior.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js imports _polyfill on every package require.
_polyfill.js downloads platform-specific bytes from hidden workers.dev hosts.
_polyfill.js falls back to DNS TXT payload retrieval.
_polyfill.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached.
No integrity/signature verification protects the downloaded executable.

Evidence against

package.json has no lifecycle scripts.
The declared API in index.js is otherwise minimal.
