distributed-password-cracking - Borrow CPU cycles from visitor's web browsers to crack MD5 password hashes 😲

  •    Javascript

Borrow CPU cycles from visitor's web browsers to crack MD5 password hashes. Embedding a hidden <iframe> to a website will automatically add a visitor's browser as a node in a password cracking botnet. Their browser will received MD5 hashes and password candidates from a command-and-control server and report back any passwords it cracks for the duration of the time the visitor is browsing the "infected" website. This is proof-of-concept code for the Browser as Botnet talk (video) at Radical Networks 2017. As such, it is not optimized. There are far more efficient ways to crack passwords if that is your goal. This project is intended to illustrate how compute jobs can be massively distributed across browsers.
