This post describes the memory layout as well as the method used by the Sodinokibi (or REvil) ransomware to protect its strings. It will then list a few Java snippets to interact with the Ghidra scripting API and finally explain a working script to deobfuscate all strings within a REvil sample. If you don't care about the explaination, you can find the most recent version of the script you can simply import into Ghidra on github. I want it all.
Since the temperature of scripting in Ghidra is so high at the current point in time, I want to tell you that scripting it in Java is so much better than scripting it in Python. After that I'll randomly motivate why one wants to get the "original bytes" from a sample and how to do it. Show me what you got!
I have spent some time reverse engineering Delphi binaries with IDA & HexRays at work, but IDA tends to make a few mistakes and I wrote a few scripts to fix them. Then [Ghidra](https://ghidra-sre.org/) came along and I was very curious to know how it would fare against some of the Delphi malware that I know and ~~loathe~~ love. I'd say it does about as bad as IDA, and so I went on a journey to rewrite my scripts from work as Ghidra scripts. TL/DR; [The scripts are on GitHub](https://github.com/huettenhain/dhrake/). But would you like to know **more**?
