AskJOE

What is AskJOE?

AskJoe is a tool that utilizes OpenAI to assist researchers wanting to use Ghidra as their malware analysis tool. It was based on the Gepetto idea. With its capabilities, OpenAI highly simplifies the practice of reverse engineering, allowing researchers to better detect and mitigate threats.

The tool is free to use, under the limitations of Github.

Limitations

OpenAI has a hard limit of 4096 tokens for each API call, so if your text is longer than that, you'll need to split it up. However, OpenAI currently does not support stateful conversations over multiple API calls, which means it does not remember the previous API call.

By now, It only supports Linux OS.

How to install?

Copy the AskJOE.py, JOES.png and AskJOE folder.
