New Malicious CVE NOT AVAILABLE CWE-506  (opens in a new tab)

How to fix?

Avoid using all malicious instances of the tailwind-mainanimation package.

Overview

tailwind-mainanimation is a malicious package. Upon installation, it silently injects obfuscated JavaScript into the end of legitimate project configuration files (like tailwind.config.js).

To evade detection, the malware rewrites git history, forging timestamps so the malicious commit appears untouched. The injected script acts as a blockchain-based dead drop resolver, querying TRON or Aptos networks to retrieve and decrypt the final Beavertail malware payload. This payload steals credentials and cryptocurrency, and installs a Remote Access Trojan (RAT) via detached child processes for long-term persistence.
