FakeIKEd, or fiked for short, is a fake IKE daemon supporting just enough of the standards and Cisco extensions to attack commonly found insecure Cisco VPN PSK+XAUTH based IPsec authentication setups in what could be described as a semi MitM attack. Fiked can impersonate a VPN gateway’s IKE responder in order to capture XAUTH login credentials; it doesn’t currently do the client part of full MitM.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
Getting started
Install on Kali Linux with `sudo apt install fiked`. See the official Kali tool page and upstream homepage linked above for full usage and configuration details.
