I figured out a generic way to generate those polyglots! Introducing: bppb! This PoC takes 2 files, a bplist and a protobuf, and merges them into one unholy abomination. #bplist #protobuf #polyglot #dfir #digitalforensics
Annoyingly, I created a bplist-protobuf polyglot. This one is a valid protobuf containing 2 LengthValues in an array. As a bplist, it's a dictionary with 2 Key-Value-Pairs. Hex here: #DFIR #MobileForensics #DigitalForensics
