## What is MAL-2026-3717?

MAL-2026-3717 is a malicious package in truffle-js, published on 13 May 2026. 

### Official description

The package.json lifecycle script invokes require('child_process').execSync with a curl command at install time. Running curl through child_process during an npm install lifecycle hook causes any installer to execute remote content fetched over the network, without consent, as soon as `npm install` runs. The package name also resembles the widely-used 'truffle' Ethereum development toolkit, consistent with a typosquat lure. There is no legitimate reason for a small utility package to shell out to curl from its package.json install hook.

The OpenSSF Package Analysis project identified 'truffle-js' @ 2.0.0 (npm) as malicious.

It is considered malicious because:

- The package executes one or more commands associated with malicious behavior.
