Command and Control & Tunnelling via ICMP

Jul 28, 2019 · You can observe from the image given below that the machine controls the slave machine by spawning its prompt of command. Now as we said that with the help ping, icmpsh will get the host machine's reverse shell over the icmp channel. Therefore, I simply trigger a command and use Wireshark to capture its packet to ensure the backend process. Great!!

Microtunneling - Wikipedia

Microtunneling. As the machine advances, more tunnel liner or pipe is pushed from the starting shaft, through the entry eye. Thus, the speed of the advancing machine is controlled by the speed at which the pipe is inserted into the entry eye via the extension of the hydraulic rams in the jacking frame.
