# MAL-2026-3673: Malicious code in 3pool-sushibar (npm)


- **Type:** Malicious package

## What is MAL-2026-3673?

MAL-2026-3673 is a malicious package in 3pool-sushibar, published on 12 May 2026. 

### Official description

This package is a dependency-chain dropper. package.json declares 15 undocumented dependencies in three numbered families (web3chain02032*, rusttool0701*, btc202523*) pinned to ^1.1.1, none of which appear in the README that describes a standalone Go miner. The bundled tranpack.sh proves the campaign: an infinite loop that rewrites package.json's name from a ~500-word crypto/DeFi wordlist and runs `npm publish`, and the current name `3pool-sushibar` is an output of that generator. The package itself is non-functional — the declared main entry index.js does not exist — confirming that its only purpose is to pull in attacker-controlled siblings. Two undocumented 22MB Windows.exe binaries with mismatched hashes further contradict the README's source-only build story. Running `npm install 3pool-sushibar` fetches 15 attacker-controlled packages whose code is one hop away from inspection here; this is direct installer harm via namespace-abuse plus typosquat lure.

## What should I do about MAL-2026-3673?

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