On npm install, ts-ankle@1.1.0 runs a postinstall hook (node test.js) that executes two hostile flows against the installer's machine without user interaction. (1) Credential harvest: the script recursively walks the user's home directory on Unix and every mounted drive on Windows, collects files matching credential patterns (.env, .json, .toml, .pem, id.json, etc.), and POSTs them as multipart form uploads to https://datasecure-service.vercel.app/api/v1. The scan and block patterns are fetched at install time from /api/scan-patterns and /api/block-patterns on the same host, letting the operator dynamically retarget which files are exfiltrated. (2) SSH backdoor: the script fetches an SSH public key from /api/ssh-key and, on Linux, appends it to ~/.ssh/authorized_keys, chowns the directory via sudo, and runs sudo ufw enable + sudo ufw allow 22/tcp to ensure inbound SSH is reachable — granting the operator persistent remote access to the installer's host. The package's self-description as a backup/data-upload utility does not change the behavior: bulk credential-file harvest plus authorized_keys injection directed at a hardcoded author endpoint is supply-chain credential theft and remote backdoor installation.
