“In 1976 Rodrigo’s ‘Guitar Concierto de Aranjuez’ was No 1 in the UK for only three hours because of a computer error. ”
probably a DDoS.

Well considering there was already 3 and a half pages of thread about it in 5hrs, I’d say there’s quite a few people who care.
Dumb petty argument threads should be reserved for GotFra….oh wait this is the right place.
This thread was the best thing ever until just after the start of page 4, then it got shit :(
But srsface guise This was Funneh lol =]
This is my favourite thread. Thank you, Monkeyman :D
Hi,
short update from my side. Nearly every game of the top5 teams were attacked in the past few weeks so we started to find solutions to fix it (Thx to Arie and Shox!).
How did see that the server was attacked?
All people were warping around and it was unplayable.
Did it affect all gameservers on the physical machine?
No! Just the gameserver where the top teams were playing were affected. Therefore it was no general DDOS attack to the server. It even isn’t a normal DOS attack. It seems to be a simple exploit / bug in the source engine of Valve.
Do Anti-(D)DOS Plugins help?
There are a lot of plugins out there to avoid (D)DOS attacks. Plugins as a gameserver addon (DAF), sourcemod, metamod addons and the query cache application in my blog entry. And NO. They don’t help because it is not a D(DOS) attack! We were able to play one game after the first attack and it seemed to help so I posted this blog entry. But the next day the attack was back.
What are the next steps?
Don’t know yet. Shox is working on an application to simulate this behavior and we will then try to fix it with e.g. iptables (Firewall). So far, the only chance when someone is using this exploit is
1) Go offline in steam friends
2) Play on a private server not listed in steams masterlist
3) Whitelist the players ip adress for iptables
Yes, I know that this is complicated. But these things are currently be done by all top teams for every game!
How can you help?
Forward every information you might have about this exploit and I will see what I can do. Currently we just can’t do much because we do not have the exploit. And all package information (captured with tcpdump – including udp packages) and iptables log files seemed to be “ok”.
