How Cyberbunker Took Down Spamhaus

The reason that this attack is such a big deal is because of its sheer size and the impact that it had on the entire internet. At its height, the DDoS attack was flooding Spamhaus with 300GB of data every second. To put this in perspective – that’s the equivalent to streaming 60,000 HD movies from Netflix all at the same time!

This was so much traffic that it actually slowed down entire portions of the internet! That’s right, it actually slowed down the internet itself.

Luckily, Spamhaus enlisted a company called CloudFlare to help with the attack. Other companies such as Google also helped defend against the attack by making their resources available. In order to accommodate the huge amount of traffic CloudFlare opened up 23 of its world wide data centers to absorb all of the traffic.

So you’re probably thinking, well Tech Talker thanks for the history lesson, but this internet war being waged doesn’t really involve me at all.

Don’t be so sure.

Think about this: How exactly did the attacker get enough resources to actually slow down a big chunk of the entire internet? As I explained in my episode Anatomy of a Virus, oftentimes attackers will add malware into pirated software that makes your computer a slave. It’s extremely likely that the majority of this attack was carried out by computers like yours and mine that were unwittingly running this malware.

This is why it’s extremely important to trust the software you install, and to keep an updated anti-virus. This will help to keep your computer safe from being used as a pawn in any sort of hacker attack.

If that wasn’t enough, a Tech Talker listener wrote in just a few days ago with a story about how a rogue individual from a chat room flooded her computer’s internet connection which caused it to slow severely. In this case, it sounds like she was on the receiving end of a much smaller version of a Denial of Service attack. The best way to deal with this is to contact your internet service provider and inform them of the situation. From there they can either block the traffic or change your IP address.

Here are your 4 Quick and Dirty Tips for keeping clear of DoS attacks:

  1. Keep your computer protected with updated anti-virus software.

  2. Make sure that any software you install on your computer comes from a reliable source.

  3. Don’t download or use pirated software.

  4. If you believe your home network is the target of a DoS attack, contact your ISP right away.
