Scripts by Mathy Vanhoef to test whether Wi-Fi clients or access points are vulnerable to the KRACK attack against WPA2. They include a modified hostapd instance and require network credentials, serving as a defensive testing tool rather than an attack tool.

Use cases

• test if my router is vulnerable to KRACK
• check WPA2 client devices for key reinstallation vulnerabilities
• audit Wi-Fi access point security
• verify a firmware patch fixed KRACK
• security research on WPA2 handshake vulnerabilities

When to choose

• you need to verify whether clients or APs are affected by the KRACK attack
• you have the required Wi-Fi hardware and credentials for authorized testing
• you are doing wireless security research or patch validation on Linux

When to avoid

• you want to attack networks you don't own - these are testing scripts requiring credentials
• you need a general Wi-Fi pentesting suite rather than KRACK-specific tests
• you don't run Linux with compatible wireless hardware
