“A mysterious flood of SSL packets from the Pushdo botnet, possibly an attempted DDOS attack, is not succeeding, according to the Internet Storm Center. None of the attacked sites are experiencing significant outages.

The attacked sites include government sites including the FCC, the NIH, the FBI and the CIA, not to mention smaller targets like the Australian embassy in Berlin. There are also prominent commercial sites from Microsoft, Office Depot, Mozy, GotoMeeting and Red Hat Magazine. A full list from Shadowserver can be found here.
