An automatic install hook retrieves an unverified archive from a hard-coded remote IP address and stages its binary. The package launcher subsequently executes that staged binary.

Static reason

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

Trigger

Installing the npm package runs its postinstall hook; invoking onecode runs the resolved staged binary.

Impact

A network attacker or operator controlling the endpoint can supply an arbitrary executable that will run when the package command is used.

Mechanism

The bootstrap disables TLS certificate validation, accepts redirects, downloads and extracts a tarball, and places its contents under node_modules. The launcher passes user arguments to the resolved binary through child_process.spawn.

Attack narrative

Installation automatically calls a bootstrapper that downloads a tarball from a hard-coded IP endpoint with certificate verification disabled and unrestricted redirect handling. It extracts the archive into the package's node_modules area and links its binary. The onecode launcher then spawns that binary with user arguments. This provides a remote, unverified payload path from installation to execution.

AI rationale

This is an automatic lifecycle remote-payload chain with no integrity verification and disabled TLS validation. It creates a concrete route for arbitrary code execution through a remotely supplied platform binary.
