Majority of Junk Traffic Consists of DDoS Targetted at IRC Servers

Security Service Provider Arbor Networks studied the amount of junk traffic over the total sum of Internet traffic, and found some remarkable figures when it comes to IRC traffic.

Over the past 1,5 year the company analyzed data of 70 ISP’s. The findings show that on average 4% of all traffic is junk, such as spam and DDoS attacks topping 1,5TB of data, per second.

Of this 4%, on average 1300 DDoS attacks daily makes halve of the junk traffic. But on occasions, DDoS can make 5% of the total Internet traffic. Of the monitored DDoS attacks the majority consists of TCP SYN floods and ICMP floods targeted to IRC servers.

The same survey showed email traffic making 1,5% of total traffic. Of this, 66% is spam.

The report with findings is not yet publicized but the company says it will be available soon.

    Perhaps it’s me, but I don’t quite get it, are they saying 4-5% of *internet* traffic is junk? or 4-5% of IRC traffic?

    ‘scuse my English :)

    4% of all traffic is junk, and of that 4% half is DDoS attacks. So that makes DDoS 2% of all Internet traffic. And the majorityof that DDoS traffic is targetted at IRC servers.

    Hope this made sense >:)

    On occasions it was 5% wich is quite substantial I think… But I agree, with one year survey over ‘just’ 70 ISPs its a bit of a hit ‘n miss of getting the heavy DDoS attacks counted into the total.
