Eaphammer – Targeted Evil Twin Attacks Against WPA2-Enterprise Networks

Eaphammer Logo - Targeted Evil Twin Attacks Against WPA2-Enterprise Networks

Do you know that your wireless network is can be intercept your communication and spy your activities. This is called the Evil Twin attack, hacker can create a malicious Wi-Fi that can intercept your activities.

What is an Evil Twin Attack ?

An evil twin attack is a type Wi-Fi attack that works by taking advantage of the fact that most computers and phones will only see the “name” or ESSID of a wireless network. This actually makes it very hard to distinguish between networks with the same name and same kind of encryption. This type of attack may be used to steal the passwords of unsuspecting users, either by monitoring their connections or by phishing, which involves setting up a fraudulent web site and luring people there.

The attacker snoops on Internet traffic using a bogus wireless access point. Unwitting web users may be invited to log into the attacker’s server, prompting them to enter sensitive information such as usernames and passwords.


EAPHammer is a toolkit for performing targeted evil twin attacks against WPA2-Enterprise networks. It is designed to be used in full scope wireless assessments and red team engagements. As such, focus is placed on providing an easy-to-use interface that can be leveraged to execute powerful wireless attacks with minimal manual configuration. To illustrate just how fast this tool is, our Quick Start section provides an example of how to execute a credential stealing evil twin attack against a WPA/2-EAP network in just commands.

Quick Start Guide (Kali)

Begin by cloning the eaphammer repo using the following command:

git clone https://github.com/s0lst1c3/eaphammer.git

Next run the kali-setup file as shown below to complete the eaphammer setup process. This will install dependencies and compile the project:


To setup and execute a credential stealing evil twin attack against a WPA/2-EAP network:

# generate certificates
./eaphammer --cert-wizard
# launch attack
./eaphammer -i wlan0 --channel 4 --auth wpa-eap --essid CorpWifi --creds
