Malicious code in vault-strategies (npm)

On npm install, the package's preinstall hook (preinstall: node postinstall.js || true) executes postinstall.js, which enumerates process.env and filters keys with a broad credential regex (key|secret|token|pass|private|ssh|deploy|auth|api|rpc|wallet|sentry|docker|graph|slack|host), bundles the matched values together with hostname, username, cwd, and npm configuration, and POSTs the payload over HTTPS to the hardcoded bare IP 185.130.46.35:8443/collect. Errors are swallowed via || true and try/catch so the exfiltration is silent. The version is published as 999.0.0 with description Internal package — the canonical dependency-confusion shape, designed to be auto-resolved over an organization's private vault-strategies package and fire the credential-harvest payload at install time.
