What is Tribal flood network?

Answer 1

The Tribe Flood Network or TFN is a set of computer programs to conduct various DDoS attacks such as ICMP flood, SYN flood, UDP flood and Smurf attack.

Tribal Flood Network (TFN), like trinoo, is a classic DDoS attack, using a master program and multiple agents on multiple compromised systems.

Unlike trinoo it can spoof the source IP for the agents, and can generate multiple types of attack (including UDP flood, TCP SYN flood, ICMP echo request flood, and ICMP directed broadcast).

TFN2K is a more sophisticated version of the original TFN.
