Prolexic Says AOL Is Most Infected Network on Internet
Prolexic, a provider of distributed denial of service (DDoS) solutions and security consulting products, has claimed that Deutsche Telecom, Wanadoo and AOL are Europe's top three offenders for harboring infected PCs. The findings are based on statistics taken from real DDoS attacks over the last six months. Globally, AOL was found to have the most infected network on the Internet.
DDoS attacks are coordinated by cyber terrorists, who place malicious viruses onto computers of unsuspecting broadband users, says Prolexic. When the attack is triggered these infected PCs become controlled by the cyber terrorist and simultaneously "flood" a network with fake packets, preventing legitimate traffic from accessing a system. The report also highlighted a significant change in the way DDoS attacks are being coordinated. Attacks are now focusing less on Layer-3 TCP and have shifted focus to hone in on the weakness of DDoS mitigation devices.
The primary attack of choice in the first half of 2005 was an advanced full connection based flood. This particular attack exposes the real IP address of the attacking zombie, however the sheer number of IP addresses that must be blacklisted to successfully defend against the attack places overwhelming load on mitigation hardware.
