## What is MAL-2026-12116?

MAL-2026-12116 is a malicious package in tailwind-hide-scrollbar, published on 5 Aug 2026. 

### Official description

dist/index.js appends an `eval(atob('...'))` payload after the legitimate `export default scrollbarHide;` line. The decoded payload queries Ethereum RPC endpoints (eth.blockscout.com/api, 1rpc.io/eth, eth.drpc.org, ethereum-rpc.publicnode.com, eth-mainnet.public.blastapi.io) for the latest transaction from hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, interprets bytes of the `to` field as IPv4 addresses, HTTP GETs `http://<ip>:443/0x/cls` and `http://<ip>:443/0x/ls`, XOR-decrypts the responses, then `eval`s the first stage and `spawn('node', ['-e', payload], {detached:true, stdio:'ignore', windowsHide:true}).unref()` to run the second stage detached. Inner strings such as `child_process`, `http`, `https`, `spawn`, and User-Agent are stored as `\uXXXX` unicode escapes to defeat static grep, wrapped in an outer base64 blob. The payload fires when any consumer imports the package, granting full Node-level remote code execution on the installer's host; the on-chain C2 resolution (EtherHiding) makes the destination attacker-mutable and resistant to takedowns.

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-2026-12116?

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