Update Jabbercracky DEF CON 2025: https://forum.hashpwn.net/post/793

There have been many changes since we launched this year. We now host monthly events and are planning for a competitive event this October. Every month, a casual list is released with a fun theme to practice on and be friendly to people new to the trade craft and twice a year, we aim to host a highly competitive event for the pros. The next competitive event will be on Friday Oct 10 2025 and run for a week like all events. One of our major goals is to provide a place for people to get into the trade craft, no matter the skill level. The community has been outstanding and continues to drive development, so thank you for the support!

Decompiling is pretty simple on july.bin, but you can also check the walk-through which contains its source code and also hash:plains for the challenge. Here's an online decompiler for july.bin: ||https://dogbolt.org/?id=f4642a6c-6910-47b5-9e54-283666003716||
