Evil Twin Attacks in Wireless Pentesting

An Evil Twin attack involves setting up a rogue access point with the same SSID as a legitimate network to trick users into connecting, enabling the attacker to intercept sensitive data.

Concept of the Evil Twin

An Evil Twin is essentially a malicious clone of a trusted Wi-Fi network.

It relies on the fact that client devices often automatically connect to known SSIDs with the strongest signal.

Executing the Attack

Attackers typically use tools like hostapd or WiFi Pineapple to broadcast the rogue SSID.

They may simultaneously send deauthentication packets to the legitimate AP to force clients to disconnect and reconnect to the Evil Twin.

Capturing the Data

Once connected to the rogue AP, all victim traffic flows through the attacker's machine.

This setup allows for credential harvesting via captive portals or direct interception of unencrypted traffic.
