Submission + - 30,000-node botnet attacks MasterCard, PayPal (networkworld.com)
The activists have recruited volunteers, who have banded their computers into a distributed denial of service botnet, but they are also using hacked machines to carry out these attacks, said Sean-Paul Correll of threat researcher Panda Security. "Today we observed over 3,000 computers in the voluntary botnet, but we also have knowledge of a 30k node botnet," he said.
This botnet infects computers via peer to peer filesharing systems, but it can spread via Microsoft Messenger and USB sticks as well, he said. Panda is trying to get a sample of the botnet code to analyze.
PayPal was hit late Wednesday afternoon, Pacific time, and the Paypal.com address was unresponsive into early Thursday morning. "There have been attempted DDoS attacks on paypal.com this week," said company spokesman Anuj Nayar. "The attacks slowed the website itself down for a short while, but did not significantly impact payments."
