Introduction to GEF

The GEF extension provides several features to the binary that are extremely helpful for debugging.

These are not all the commands that GEF provides. These are the ones I use most often in most debugging scenarios. For the complete list of commands, consult the GEF documentation.

I organize the commands into a few categories:

• Ease of Use: Commands that make the debugging experience easier.

• Security Measures: Commands that provide extra guidance based on the implemented security measures.

• Memory Analysis: Extra commands that show various memory segments better than the default gdb commands.

• Debugging UI: Commands to control the GEF debugging experience.

• Exploit Development: Commands useful for exploit development.

Installation

The easiest way to install GEF is through wget:

$ bash -c "$(wget https://gef.blah.cat/sh -O -)"

Usage

GEF is automatically loaded when you run gdb so no further action is required!
