ICMP Tunneling
ICMP Tunneling is a technique used in computer networking to send data through a network that would normally be blocked. ICMP (Internet Control Message Protocol) is a protocol used to send error messages and status messages between devices on a network.
In ICMP Tunneling, data is encapsulated in ICMP packets and sent through the network. This allows the data to bypass certain types of network filters that may be in place. The data is then extracted from the ICMP packets on the other end of the tunnel.
This technique can be used to bypass firewalls, evade detection by intrusion detection systems, or communicate in scenarios where regular network traffic is not allowed.
However, ICMP Tunneling has also been used for malicious purposes, such as transmitting malware or carrying out cyberattacks. Therefore, it is important to use this technique responsibly and only in situations where it is necessary.
