What is MAL-2026-12372?
MAL-2026-12372 is a malicious package in eth-crypto-utils, published on 5 Aug 2026.
Official description
On require of index.js, the package initiates an HTTPS POST to the hardcoded endpoint https://enjbyg3xk8l.x.pipedream.net/beacon carrying a JSON payload that includes the full process.env, os.hostname(), os.userInfo().username, and os.homedir(). The bulk process.env dump exposes any credentials or tokens present in the installer's environment (AWS keys, GitHub/npm tokens, CI secrets, etc.). The transmission fires as a side effect of importing the package, with no caller opt-in and no relationship to any advertised cryptographic utility functionality. The declared package name suggests Ethereum cryptography helpers, which does not match the observed beacon behavior.
What should I do about MAL-2026-12372?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
