For a good article on DDOS you should go to Gibson's site at http://www.grc.com/intro.htm. He got hit by a DDOS attack and managed to trace the attack back to its origin and even to the guy who wrote the malicious code. Sadly it's all too easy start a DDOS once you have a few thousand PC's infected with a dormant virus. All it needs is a trigger code and off they go.. bones bones@xxxxxxx -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of Peter Dodds Sent: 27 March 2009 10:49 To: jhb_airlines@xxxxxxxxxxxxx Cc: pdodds@xxxxxxxxxxxxx Subject: [jhb_airlines] Re: FSC Property Its the same with Vatsim FSCommander gets its data from the Whazzup data transfer system in both organisations that powers Servinfo (and presumable IVAO Eye). Didn't know you could get the FPs though. That is handy. Vatsim UK has had a severe DDOS attack recenctly which has wiped the UK Forum and UK-1 Server. The Us server was affected but was recovered. The mechanics of how these attacks destroy a PC I don't understand, but someone here will know I'm sure. I'd be interested. Peter.
