Parse your binaries with Kaitai WebIDE
The solution is a domain-specific language
To resolve these issues a DSL (domain-specific language) called Kaitai Struct was suggested by Mikhail Yakshin. According to the original website “Kaitai Struct is a declarative language used for describe various binary data structures, laid out in files or in memory: i.e. binary file formats, network stream packet formats, etc.
The main idea is that a particular format is described in Kaitai Struct language only once and then can be compiled with a ksc into source files in one of the supported programming languages. These modules will include a generated code for a parser that can read described data structure from a file/stream and give access to it in a nice, easy-to-comprehend API.”
webIDE for Kaitai Struct
This sounds really good. To make your life even more easier Tamás Koczka, the ex-captain and one of the key members of the !SpamAndHex CTF team created a WebIDE for Kaitai Struct. In this way, you can generate parsers for all the file formats supported by Kaitai Struct with only a few clicks.
Tamás also prepared some nice challenges on Avatao to help you learn the use of Kaitai WebIDE and also get a quick understanding of different file formats.
