The hacking tool Loki provides shell access to the attacker through what protocol:
TCP
IGMP
ICMP
UDP
Loki exploits the covert channel that exists inside of ICMP Echo traffic. ICMP Echo packets have the option to include a data section. This data section is used when the record route option is specified, or, the more common case, (usually the default) to store timing information to determine round-trip times. Although the payload is often timing information, there is no check by any device as to the content of the data. So, as it turns out, this amount of data can also be arbitrary in content as well. Therein lies the covert channel. Most network devices do not filter the contents of ICMP Echo traffic. They simply pass them, drop them, or return them. The trojan packets themselves are masqueraded as common ICMP Echo traffic. https://www.sans.org/security-resources/idfaq/how-can-attacker-use-icmp-for-reconnaissance/3/13
