A comprehensive framework implementing the "Win-DoS Epidemic" research, which discovered 5 critical vulnerabilities affecting Windows systems through novel attack techniques.

Created by SafeBreach Labs (Joint work of Or Yair and Shahak Morag). For the full technical analysis check out the blog post

Overview

This framework implements research that discovered 5 critical vulnerabilities affecting Windows systems:

Win-DoS Vulnerabilities (4)

LDAP Referral DoS (CVE-2025-32724) - Memory exhaustion via massive LDAP referral lists affecting Domain Controllers
NetLogon RPC DoS #1 (CVE-2025-26673) - Memory exhaustion in NetrServerReqChallenge function affecting Domain Controllers
NetLogon RPC DoS #2 (CVE-2025-49716) - Memory exhaustion in DsrAddressToSiteNamesW function affecting Domain Controllers
Spoolsv RPC DoS (CVE-2025-49722) - Memory exhaustion in RpcEnumPrinters function affecting all Windows endpoints

Win-DDoS Vulnerability (1)

LDAP Referral DDoS (CVE-2025-32724) - Leveraging Domain Controllers as DDoS botnet participants without authentication

Setup

Clone the repository:
```
git clone <repository-url>
cd Win-DoS
```
Install dependencies for specific modules:
- For LDAP attacks: cd ldap_attacks && pip install -r requirements.txt
- For RPC attacks: cd rpc_attacks && pip install -r requirements.txt

Module Documentation

LDAP Attacks

Implements the LDAP referral attacks we discovered. Features:

DoS Mode: Memory exhaustion via massive LDAP referral lists (500,000+ URLs)
DDoS Mode: Leveraging Domain Controllers as botnet participants

RPC Attacks

Implements the RPC memory exhaustion attacks we discovered. Features:

TorpeDoS technique: Pre-bind thousands of clients without waiting for bind acks, pre-sign packets if needed, and flood victims with many RPC calls at once
