DDoS attacks happen to online systems across the spectrum: from commercial entities to government institutions. These are often random attacks without a specific target, which aim to disable as many online services as possible, but even targeted attacks are not so unique, while these attacks may also occur on the basis of a third party order.
An attack against any target can be ordered by practically anyone through a number of anonymous online services. It might be a competitor, a disgruntled client or a hired employee. The lightest attack, lasting several tens of minutes, can take in just under 5 euros. The amount a client pays for a day-long attack starts from 50 euros. In many cases, the victim is exposed to several different attacks simultaneously, for several days or weeks.
