I guess it was just a matter of time that Fraudwatchers.org would be completely shut down because of a massive botnet DDoS attack that started in August. Even after moving to another server, the attacks got more intense! This goes to show you that botnets are still a very real and serious threat. While Fraudwatchers.org couldn’t stop an attack like this (mostly because of cost and feasibility issues) other sites like CastleCops have been dealing with this for sometime as well. This could really happen to any organization, not just anti-fraud/crime websites. Unless an organization has some serious cash, how can one defend against something like this?
Good article about this over at Darkreading.org.
Here is a good site with some ideas on how to prevent DDoS attacks. Not a whole lot of information out there, hopefully there is more research done on this subject soon.
