INFORMATION

D.D.O.S. … Distributed Denial of Service. A form of network denial of service (DoS) attack in which a master computer controls a number of client computers to flood the target (or victim) with traffic, using backdoor agent, client, or zombie software on a number of client machines. The master computer will attempt to control these machines and coordinate an attack on a target. The master computer never contacts the target directly, and the large number of zombie machines multiplies the force of the attack. The zombie program is generally distributed as some form of trojan horse, although zombies may be installed if control has already been obtained by means of a RAT. Usage of the acronym, DDoS, in preference to the full phrase is almost universal. DEA see Data Encryption Algorithm
