Intercept all traffic containing HTTP signature: hping3 -9 HTTP -I eth0.Scan entire subnet for live host: hping3 -1 10.0.1.x -rand-dest -I eth0.FIN, PUSH and URG scan on port 80: hping3 -F -P -U 10.0.0.25 -p 80.Firewalls and Time Stamps: hping3 -S 72.14.207.99 -p 80 -tcp-timestamp.Collecting Initial Sequence Number: hping3 192.168.1.103 -Q -p 139 -s.It can be used for network security auditing, firewall testing, manual path MTU discovery, advanced traceroute, remote OS fingerprinting, remote uptime guessing, TCP/IP stacks auditing, etc.Command line network scanning and packet crafting tool for the TCP/IP protocol.Attacker uses Nmap to extract information such as live hosts on the network, services (application name and version), type of packet filters/firewalls, operating systems and OS versions.Network administrators can use Nmap for network inventory, managing service upgrade schedules, and monitoring host or service uptime.Scanning IPv6 network, however, offers a large number of hosts in a subnet if an attacker can compromise one host in the subnet attacker can probe the " all hosts" link local multicast address.Attackers need to harvest IPv6 addresses from network traffic, recorded logs or Received from: and other header lines in archived email or Usenet news messages.Scanning in IPv6 network is more difficult and complex than the IPv4 and also some scanning tools do not support ping sweeps on IPv6 networks.Traditional network scanning techniques will be computationally less feasible due to larger search space (64 bits of host address space or 2^64 addresses) provided by IPv6 in a subnet.
Attacker may use UPnP SSDP M-SEARCH information discovery tool to check if the machine is vulnerable to UPnP exploits or not.Vulnerabilities in UPnP may allow attackers to launch Buffer overflow or DoS attacks.The Simple Service Discovery Protocol (SSDP) is a network protocol that works in conjunction with UPnP to detect plug and play devices available in a network.CEH Scanning Methodology - Check for Open Ports SSDP Scanning
