## What is MAL-2026-14512?

MAL-2026-14512 is a malicious package in tailwind-scrollbar-hider, published on 25 Aug 2026. 

### Official description

dist/index.js exports a small legitimate scrollbarHide Tailwind plugin and then executes `eval(atob('<~39KB base64>'))` at module top level, so the payload runs on any require()/import of the package. The decoded body is packed with an obfuscator.io-style string-array dispatcher (`_0x355e` / `_0x12f0` with shuffling) that hides all string literals, and it dynamically resolves `node:http`, `node:https`, `node:zlib`, and `child_process.spawn` via `createRequire(import.meta.url)`. At runtime it assembles an Ethereum RPC endpoint list from `process.env.ETH_RPC_URL` plus hardcoded providers including `*.publicnode.com` and `h.drpc.org`, together with an indexer URL and a hardcoded `SENDER` Ethereum address, and issues `eth_blockNumber` and block-range requests — the shape of an on-chain wallet-monitoring / drainer relay embedded in a CSS-only utility. A Tailwind scrollbar-hiding plugin has no legitimate need to eval a base64 blob, spawn child processes, open network sockets, or scan Ethereum blocks on import.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-14512?

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