Fiked Fake IKE Daemon

Fiked is a fake IKE daemon that supports just enough of the standards and Cisco extensions to attack commonly found insecure Cisco PSK+XAUTH VPN setups in what could be described as a semi-MitM attack. Basically, knowing the pre-shared key, also known as shared secret or group password, the VPN gateway can be impersonated in IKE phase 1, in order to learn XAUTH user credentials in phase 2. The configuration supported by fiked is IKE aggressive mode using pre-shared keys and XAUTH. Supported algorithms are DES, 3DES, AES128, AES192, AES256, MD5, SHA1, and DH groups 1, 2, and 5. Main mode is not supported.
