Callgraphs with Ghidra, Pyhidra, and Jpype

22 January 2023 at 02:40
TLDR; This post will teach you how to leverage Ghidra’s FlatProgramAPI and Python 3 to generate function call graphs. Ghidra scripting with Python 3, powered by Pyhidra (via Jpype), provides robust access to Ghidra’s SRE toolset for binary analysis. To follow along, clone the repo at ghidra-pyhidra-callgraphs. Ghidra, Pyhidra (via Jpype), and Callgraphs Oh My! Ghidra continues to impress me w...

TL;DR - Windows RPC enumeration, discovery, and auditing via NtObjectManager. We will audit the vulnerable RPC interfaces that lead to PetitPotam, discover how they have changed over the past year, and overcome some common RPC auditing pitfalls. I was inspired by From RpcView to PetitPotam from @itm4n, an excellent post that taught me how to use RpcView to discover the RPC interfaces and in pa...
