This talk will focus on a paste-service-crawler able to handle large amounts of data and intelligent to automate extraction of leaks and generating wordlists.

Efficient wordlists are one tool for hash-checking tasks. Most are compiled from leaks which are released often through paste-services. These paste-services offer, besides leaks, also fundamental data for wordlist creation as it covers all kind of human communication. As there are many different paste services with different features, and each of them offer a vast amount of data, it's not an easy task to use these resources.
