On npm install, postinstall.js collects git identity, OS user/uid, hostname, internal network interface addresses, Cloudflare Pages environment variables, and directory listings of ~/.ssh, ~/.aws, and ~/.kube (first 5 entries of each), base64-encodes the payload, and sends it as a query string via an HTTPS GET to ho9skv69a3pbqzbzg7z1l009c0ir6hu6.oastify.com — a Burp Collaborator out-of-band exfiltration host. The script also implements explicit sandbox evasion: it returns early if the current working directory starts with /tmp, contains 'npm-', or HOME is unset, with a 'Diagnostic/2.0' User-Agent cover story. The targeted directories (~/.ssh, ~/.aws, ~/.kube) reveal credential filenames (id_rsa, credentials, config) suitable for follow-on targeted theft. The package name shape and dependency-confusion-style high version (99.12.9) are consistent with an internal-name squat reconnaissance payload.

The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
