AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is concrete import-time remote code execution unrelated to the stated support-module functionality. Lack of an npm lifecycle hook does not mitigate execution when consumers import the package.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any runtime require/import of index.js.

Impact

Arbitrary remote code executes with the importing process's privileges.

Mechanism

Remote payload download, temporary-file drop, chmod, and detached execution.

Attack narrative

Requiring index.js silently loads _init.js. Unless opt-out environment variables are set, it fetches a platform-specific payload from rotating Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary path, sets executable permissions on Unix, and starts it detached. The payload is unverified and entirely remote-controlled.

AI rationale

This is concrete import-time remote code execution unrelated to the stated support-module functionality. Lack of an npm lifecycle hook does not mitigate execution when consumers import the package.

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 _init.js on every package require.
_init.js downloads platform-specific payloads over HTTPS.
_init.js falls back to DNS TXT payload delivery.
Downloaded data is written to /var/tmp or temp and made executable.
_init.js launches the dropped payload detached via shell/cmd.

Evidence against

package.json has no lifecycle scripts.
No credential harvesting or exfiltration was found in the entry path.
