Installation downloads an unverified native archive from a fixed IP address while disabling TLS certificate validation. It extracts and marks the supplied binary executable; the onecode launcher later spawns it.

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

npm installation, followed by running the onecode command

Impact

The remote server can supply a native executable that is installed into the consumer dependency tree and executed when the CLI is used.

Mechanism

Postinstall remote native payload download, extraction, and launcher execution

Attack narrative

On installation, the package runs its bootstrapper automatically. The bootstrapper fetches a versioned archive from a hard-coded IP address with certificate validation disabled, extracts it into node_modules, and marks its native binary executable. The shipped launcher selects that cached binary and spawns it when the user runs onecode. This gives the remote host control over executable code placed in the consumer installation without a source-visible integrity check.

AI rationale

This is an automatic lifecycle-based remote native payload installer that disables TLS verification and has no visible integrity validation. The later launcher execution completes a concrete remote code delivery path.
