## What is MAL-2026-12330?

MAL-2026-12330 is a malicious package in @vboxdev/common, published on 5 Aug 2026. 

### Official description

build/index.js appends an eval(atob('...')) block that fires when the module is required. The decoded payload queries Ethereum JSON-RPC endpoints (eth.blockscout.com, 1rpc.io/eth, eth.drpc.org, blastapi.io) for transactions from a hardcoded attacker wallet (0xa322E5f3D311D3080e6f01210639aDC2490Ef1a), reconstructs an IPv4 address from the bytes of tx.to, then fetches http://<resolved-ip>:443/0x/cls and http://<resolved-ip>:443/0x/ls. The response body is XOR-decoded with a hardcoded key and executed via eval() and a detached spawn('node','-e',...) child process (detached:true, stdio:'ignore', windowsHide:true, unref()). The C2 endpoint is mutable — the attacker rotates it by publishing new on-chain transactions from the controlled wallet — giving persistent remote code execution on any machine that imports the library. All require targets, URLs, HTTP header/method names, and error strings in the appended region are written as \u00XX unicode escapes and wrapped in base64+atob+eval; the legitimate __exportStar re-exports above the appended block are plain text, so the sole obfuscated region is the loader.

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-2026-12330?

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