EITHER/XOR
Security researchers have uncovered a network of infected Linux computers that's flooding gaming and education sites with as much as 150 gigabytes per second of malicious traffic—enough in some cases to take the targets completely offline.
The XOR DDoS or Xor.DDoS botnet, as the distributed denial-of-service network has been dubbed, targets as many as 20 sites each day, according to an advisory published Tuesday by content delivery network Akamai Technologies. About 90 percent of the targets are located in Asia. In some cases, the IP address of the participating bot is spoofed in a way that makes the compromised machines appear to be part of the network being targeted. That technique can make it harder for defenders to stop the attack.
