Explanation: In such a situation, John will use the SuperScan tool to find the open ports and applications on the We-are-secure network. SuperScan is a TCP/UDP port scanner. It also works as a ping sweeper and hostname resolver. It can ping a given range of IP addresses and resolve the host name of the remote system. The features of SuperScan are as follows: It scans any port range from a built-in list or any given range. It performs ping scans and port scans using any IP range. It modifies the port list and port descriptions using the built in editor. It connects to any discovered open port using user-specified “helper” applications. It has the transmission speed control utility. Answer: C, A, and B are incorrect. RIPE, ARIN, and APNIC are the Regional Internet Registries (RIR) that manage, distribute, and register public IP addresses within their respective regions. These can be used as passive tools by an attacker to determine the network range.
