AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete import-time staged payload chain with remote code execution, unrelated to the advertised abstraction API. The lack of lifecycle scripts does not mitigate execution on normal package use.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Any application require/import of index.js

Impact

Unconsented arbitrary native code execution in the importing application's user context.

Mechanism

remote binary download, drop, chmod, and detached execution

Attack narrative

Requiring index.js silently loads _runtime.js. The loader contacts hard-coded HTTPS hosts for a platform-specific payload, falls back to DNS TXT chunk retrieval, writes payload bytes to a temporary executable file, marks Unix files executable, and launches them detached through a shell or cmd.exe. A temp lock only throttles repeat execution.

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 _runtime.js on every package require.
_runtime.js fetches platform binaries over HTTPS and DNS TXT.
_runtime.js writes downloaded data to /var/tmp or Windows Temp.
_runtime.js chmods and detached-spawns the downloaded file.
Remote hosts and DNS domains are hard-coded and obfuscated by string joins.

Evidence against

package.json has no lifecycle scripts.
No credential or environment-value exfiltration was found.
