Cyber Attacks – increasing in severity and frequency

In late March 2013, a massive cyber attack took place, not between warring nations but between an anti-spam group and a hosting service that rents server space to spammers. It resulted in what experts are calling the largest denial-of-service attack in the history of the Internet.
The players were Spamhous, a European group fighting spam, and Cyberbunker, a Dutch company that rents server space to a wide variety of clients, including those that send out spam. When Spamhous added Cyberbunker to its blacklist, war broke out.
Swarms of computers suddenly started sending out huge data streams. In this latest attack, cyber warriors exploited the Internet’s Domain Naming System (DNS), bombarding Spamhous’ servers with data requests. Very soon, the servers couldn’t be reached by anyone else.
But the effects didn’t stop there. Many Internet users in Europe and North America found the Internet suddenly slowed or ground to a halt. Some found streaming a video on Netflix next to impossible. Others had trouble reaching websites they visit on a daily basis.
Tier One service providers, who carry the bulk of Internet traffic, were simply overwhelmed by the volume of traffic from this attack. The signals you send from your computer to reach a particular place on the network had to contend with this huge overload of traffic. In this case consumers were collateral damage.
But more may be at stake than inconvenience. Some believe that money and lives could be at risk due to the rising levels of cyber warfare.
