🛡️ MAL-2026-5781 — portal-backend

Malicious code in portal-backend (npm)

Source: amazon-inspector

On npm install, the package's preinstall hook executes postinstall.js, which enumerates process.env and filters keys matching a broad credential-shaped regex (key|secret|token|pass|private|ssh|deploy|auth|api|rpc|wallet|sentry|docker|graph|slack|host), then bundles those values together with os.hostname(), os.userInfo().username, process.cwd(), and npm registry config into a JSON payload and POSTs it via https.request to 185.130.46.35:8443/collect — a bare IP with no relation to any publisher domain. The source even self-identifies the behavior in a comment ("Exfil CI environment variables on install"). The package itself is hollow: index.js is module.exports = {}, the description is the generic "Internal package," and the version is 999.0.0 — the canonical dependency-confusion shape designed to outrank a private registry's portal-backend and have misconfigured installers fetch this public copy instead. Installing this package on any developer or CI machine immediately ships that machine's CI secrets, deploy tokens, SSH/registry credentials, and host identity to the attacker.
