Today it has been reported a DDOS attack is taking place against the anti spam provider Spamhaus
this attack is considered the largest attack recorded with over 300 GBPS of traffic going towards
spamhaus networks spamhaus states that due to their spread out infrastructure
the attack comes after Spams blocked access to a web hosting company called cyberbunker a web hosting company that states it will host any content except child porn and terrorism Spamhaus decided it would block cyberbunker to stop spam originating from the websites and servers being hosted by cyberbunker.
now to put this into perspective a DDOS attack that generates 1GBPS of traffic is enough to disrupt many small business networks about 20-30 is what we see in a average DDOS 80 is considered a large attack so what were are seeing now with 300 is massive and until today was unheard of this also raises concerns for future attacks as this shows the true power some attackers have at their disposal
How does a Denial of service attack work
A denial of service attack works by flooding a network with traffic in an effort to bring down the service attache to it for example if the target is a website the attacker will flood the website with so much HTTP traffic that legitimate users who want to access the site will find the server to be unable to respond to the request of that user because the site has been flooded with bogus traffic now that are many different way to perform a DDOS attack for example in this case the attacker may be flood the spamhus’s DNS servers with bogus DNS requests or they could also be flooding the servers with bogus TCP traffic but in the end the attack is the same in that its meant to saturate all the links to the given server
We will see what outcome of this attack brings …
Till next time
Stay secure !!
