DDOS Attacks In 2012| DDOS tools 2012 |
2011 has been the year where massive DDOS attacks tooks place and most of them were directed by a group of hacktivists called Anonymous and lulzsec. DDOS attacks have totally moved from layer 4 to layer 7 as in layer 4, A hacker would need thousands of computers to attack a single server, where as in Layer 7 DDOS a hacker can easily take down a server with a single computer provided that if it's vulnerable. For those of you who don't know a DOS attack is a method of exhausting a server's resources and compromising it's availability.
Apache killer is a DDOS/DOS tool written in Perl which sends HTTP GET REQUESTS with multiple byte ranges, These byte ranges occupy a wide variety of portions in the memory space which when abused causes Apache to malfunction.
Slowloris was also witnessed in the wild, however the intensity of this tool was pretty less then apache killer. Slowloris abuses handling of HTTP request headers
Where in 2011 Apache killer was seen to attack Apache webservers, A tool named R-U-Dead-Yet was also witnessed in wild exploiting HTTP Post Request in order to attack a IIS server. It implements DOS attack via long field submissions.
LOIC( Low Orbit Ion Canon )
With Apache killer and other tools getting patched on the server side, it was really difficult for the hacktivists to exploit big targets?, So how did they do so?. They used a famous tool called Low Orbit cannon or LOIC for short is by far one of the most famous DDOS tool even. Anonymous used this tool to exploit take down major targets such as payoneer.
But what's so amazing about this tool as this tool is nearly unstoppable if it's being used by a massive number of audience to target a single website. It performs a DDOS attack by continuously sending a HTTP request. But what's more important to note about this tool is that in 2011, there were about 381,976 downloads. However this download amount has been already surpassed 2 months before in 2012
