# WSUS Security Research Toolkit
## Overview
A Python-based security research framework for analyzing Windows Server Update Services (WSUS) deserialization handling. This toolkit helps security professionals and researchers understand how WSUS processes serialized .NET objects through SOAP endpoints.
**Target Audience:** Security researchers, penetration testers (with proper authorization), and IT administrators looking to assess their WSUS infrastructure.
## Features
- ๐ฌ Analyze WSUS deserialization behavior
- ๐ Generate detailed reports on endpoint responses
- ๐ก๏ธ Help identify configuration weaknesses in lab environments
- ๐ Educational reference for .NET serialization patterns
## System Requirements
| Component | Requirement |
|-----------|-------------|
| OS | Windows 10/11, Linux (Ubuntu 20.04+) |
| Python | 3.4 or higher |
| Network | Access to target WSUS instance |
## Quick Start
### Configuration Options
The toolkit accepts serialized test data in Base64 format. You have two options:
**Option A:** Add your test data to `payload.txt`:
```
YOUR_TEST_DATA_HERE
```
**Option B:** Modify directly in `exp.py`:
```python
...
if not args.no_wait:
time.sleep(0.02)
injected = payload_text or 'your_payload'
success, event_id, target_sid = send_malicious_event(target, cookie, injected)
...
```
### Running the Analysis
```bash
python exp.py http://example.local:8533
```
*(Replace with your lab WSUS server URL)*
## Technical Details
| File | Purpose |
|------|---------|
| `encrypt.py` | Prepares test data blobs matching WSUS expected format |
| `exp.py` | Constructs and sends SOAP requests for analysis |
The toolkit simulates how WSUS handles incoming serialized objects, allowing researchers to observe the deserialization process in controlled environments.
