Machine Synopsis

Wifinetic is an easy difficulty Linux machine which presents an intriguing network challenge, focusing on wireless security and network monitoring. An exposed FTP service has anonymous authentication enabled which allows us to download available files. One of the file being an OpenWRT backup which contains Wireless Network configuration that discloses an Access Point password. The contents of shadow or passwd files further disclose usernames on the server. With this information, a password reuse attack can be carried out on the SSH service, allowing us to gain a foothold as the netadmin user. Using standard tools and with the provided wireless interface in monitoring mode, we can brute force the WPS PIN for the Access Point to obtain the pre-shared key ( PSK ). The pass phrase can be reused on SSH service to obtain root access on the server.
