What is MAL-2026-14276?
MAL-2026-14276 is a malicious package in node_cryptography, published on 19 Aug 2026.
Official description
The package presents itself as a Node.js cryptography helper and depends on ethers, encouraging callers to pass cryptographic or wallet material to its sole exported async function. That function forwards the caller's argument via axios to an API_BASE_URL assembled at runtime from ~13 fragments produced by an obfuscator.io RC4 string-array decoder. The entire ~30 KB index.js is wrapped in the standard obfuscator.io scheme (RC4+base64 string array, hex-escaped literals, wrapped index accessors, array-rotation IIFE, and a self-defending RegExp function-body anti-tamper check) whose only purpose here is to hide the destination URL. The caller does not configure this destination and is not informed of it; normal use of the advertised API silently leaks the caller's cryptographic inputs to an author-controlled host.
What should I do about MAL-2026-14276?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
