What an honor, 2 of our best giving an awesome talk about #fuzzing at the amazing BlueHat IL conference

PlaidCTF included a regex parser in FAT32. I ended up solving it by ignoring the challenge idea acepace.net/ctf/misc/2020/… Thanks to 8051 enthusiast for creating regex2fat and helping me laugh a lot and thanks to 5BC for the fun!

TBH I really can't believe this isn't crypto, great write up from one our team members. #GoogleCTF #Miscrypto
