advanced-threat-research-GhidraScripts/Automagic.java

//This script is meant to automate the usage of temporary FIDBs, allows you to use multiple BSim databases per file to recover functions, use file metadata recovery scripts (Golang or Nim, for example), and allows you to use a LLM to further annotate the code. Next, the script adds some graphical elements by colourising complex function calls as dark red while non-complex functions are marked as light red.
