Tool to brute force APPLIDs on a z/OS mainframe where you can connect to VTAM Truthfully, it's just a useful way of automating mainframe screen interactions, i.e. I make copies of this to perform specific fuzzing/user enum/password bruting attacks against custom apps It is a fork from mainframed's https://github.com/mainframed/TSO-Brute and most of the credit goes to him If you want to brute TSO usernames/passwords rather use his psiotik tool https://github.com/mainframed/psikotik Two most useful improvements are the error-aware safe_send and find_response extensions of py3270
