## What it is
PrivExchange is a set of Python proof-of-concept tools that abuse Exchange Web Services push notifications to relay authentication and escalate privileges to Domain Admin. It includes a standalone attack tool and an ntlmrelayx attack module for credential-less exploitation.

## Use cases
- abuse Exchange push subscriptions to capture SYSTEM authentication
- relay NTLM authentication to escalate to Domain Admin
- demonstrate Exchange privilege escalation vulnerabilities in pentests
- test whether Exchange servers are patched against PrivExchange attacks
- integrate an Exchange attack module into ntlmrelayx workflows

## When to choose
- you are performing an authorized penetration test against an Active Directory environment with Exchange
- you need to verify whether Exchange servers are vulnerable to the pushSubscription abuse
- you want a lightweight impacket-based relay attack tool

## When to avoid
- you need a maintained tool with recent updates and support for modern Exchange
- you are not authorized to test the target environment
- your target runs patched Exchange with the vulnerability mitigated
