Microsoft's UF2 file format is used to distribute updates for various software products, including Windows, Office, and Visual Studio. UF2 files are essentially container files that hold update payloads, metadata, and digital signatures. While UF2 files are widely used, their internal structure and content are not well understood, making it challenging for researchers and developers to analyze and work with these files. # Read UF2 file digital signature digital_signature_offset =

UF2 (Microsoft Update Format 2) is a file format used by Microsoft to distribute updates for various software products. While UF2 files are widely used, there is limited publicly available information on their internal structure and content. This paper presents UF2 Decompiler, a tool designed to reverse-engineer UF2 files and extract their contents. We describe the UF2 file format, the design and implementation of the UF2 Decompiler, and its capabilities. import struct import hashlib UF2 (Microsoft Update Format
