On npm install, the package's preinstall hook (node postinstall.js || true) executes automatically. The script collects hostname, username, and current working directory, then iterates process.env and filters keys matching the regex /key|secret|token|pass|private|ssh|deploy|auth|api|rpc|wallet|sentry|docker|graph|slack|host/i, capturing CI tokens, SSH keys, deploy credentials, cloud API keys, RPC/wallet secrets, and similar. The collected JSON payload is POSTed via https.request to the hardcoded bare IP 185.130.46.35:8443/collect. The package metadata reinforces the attack shape: version 999.0.0 and description "Internal package" are the canonical dependency-confusion pattern, intended to override an organization's internal vaults-monitor-cron package. The || true suffix on the preinstall command swallows errors so the install appears to succeed silently. There is no legitimate functionality in the package — its sole on-install effect is credential exfiltration.
