Blooming heck! A ridiculously large (the biggest ever) Distributed Denial of Service attack is currently slowing global internet traffic. Approximately 300 gigabits per second are hammering Spamhaus, an anti-spam company that creates blacklists containing dodgy websites that it sells to ISPs.
Spamhaus is estimated to be responsible for blocking up to 80% of global spam emails. This company has been attacked many times in the past but nothing on the scale of the current attack. The likely source is Cyberbunker, a curious venture that’s literally a data center in a nuclear bunker. Cyberbunker operates on an unusual ethos, offering storage and hosting to anything “except child porn and anything related to terrorism”. This has meant that Spamhaus has blacklisted the entire data center labeling it a “spammers haven”.
Cyberbunker has not directly claimed responsibility for the attack but Sven Olaf Kamphuis, claiming to be a spokesman for Cyberbunker told the BBC that Spamhaus shouldn’t be able to determine “what goes and does not go on the Internet”.
Cloudflare have been called in to mitigate the attack. Conventional DDOS attacks use botnets to try to knock servers offline with an unmanageable stream of requests. Interestingly this attack is different. Using a flaw in the Domain Name System, the hackers are using global traffic to attack Spamhaus on an unprecedented scale.
The sheer amount of traffic being syphoned into Spamhaus is clogging up the entire internet and causing general chaos. This attack is proving hard to stop as you can’t simply turn off DNS. I wonder what Gibson Index level this attack is? [mashable]
