Security experts concede the concept is nothing new.
Now a new breed of DoS attacks has surfaced that is even more powerful. Some security experts warn that these new attacks, which can harness the power of as many as 1,000 PCs, signal the next phase in Internet security. A DoS attack is designed to bring down a network by flooding it with large amounts of traffic, and is typically launched from a single machine. But in an attack using distributed technology, intruders use two exploit tools, trin00 and Tribe Flood Network, to sniff out security vulnerabilities in a multitude of systems. Once those sytems are penetrated, the attacker uses that network of machines to direct a distributed flood attack against a single target.
