APIs in NodeJS should have a single source of truth for api specs between code and docs, as well as compile time type safety.

`npm install` executes `test.js`, which downloads a remote SSH key and scanning patterns, modifies the user's SSH authorization, scans local files, and uploads matches. It also exfiltrates sensitive configuration files from the install working directory.

Static reason

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

Trigger

npm postinstall

Impact

Unauthorized SSH persistence, firewall modification, and theft of local credentials/configuration data.

Mechanism

remote-key persistence plus recursive file collection and HTTP exfiltration

Attack narrative

On npm postinstall, `test.js` calls both exported routines. One downloads an SSH public key and remotely supplied scan/block patterns, appends the key to the current user's `authorized_keys`, attempts ownership changes, enables UFW, and opens port 22. It then scans the user's home directory or Windows drives for remotely selected filenames and uploads matching files. The second routine recursively finds `.env`, `env`, `id.json`, and TOML configuration files beneath the install working directory and uploads their contents with the local username.

Rationale

The package contains an install-time, remotely directed persistence and data-exfiltration chain. The copied unrelated README does not describe or justify this behavior.
