One third of network addresses subjected to denial-of-service attacks over two-year period, says study

The results of this study are gigantic compared to what the big companies have been reporting to the public.

This is something we just didnt see coming.

The study has been published in the Proceedings of the Association for Computing Machinery (IMC 17).

A third of the Internet is under attack

A /24 is a block of 256 IP addresses, usually assigned to a single organization.

Both the direct and reflection attacks affected 137,000 targets during the study period.

These absolute numbers are staggering, a thousand times bigger than other reports have shown.

Several third-party organizations that offer website hosting were also identified as major targets.

GoDaddy, Google Cloud, and Wix were the three most frequently attacked larger parties over the two year-period.

Others included Squarespace, Gandi, and OVH.

Most of the times, its the customer who is being attacked, explained Dainotti.

So if you have a larger number of customers, youre likely to have more attacks.

If youre hosting millions of websites, of course, youre going to see more attacks.
