## What is MAL-2026-5783?

MAL-2026-5783 is a malicious package in vault-strategies, published on 15 Jun 2026. 

### Official description

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.

## What should I do about MAL-2026-5783?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
