Protocol Buffers for Forensic Examiners: The Varint Trap
Protobuf varints are not SQLite varints. Learn how to parse Protocol Buffer data from Apple Notes and mobile forensic artifacts, decode LEB128 varints step by step, and build a Python decoder with bitwise operations. Includes a hands-on XOR decryption challenge.








Thank you for a great course! I finally get how to work with unsupported apps. That clicked during this course. I’ve done a few trainings before, but this one stood out because it was actually useful right away. The instructor explained how app data is stored in a way that made sense, and I really appreciated all the real examples. I’ve already used a few techniques in a current case.
