Fbi Shuts Down the 15 ‘ DdoS-For-Hire ‘ sitesByBill Toulas-21 December 2018.934Figure 1 The warning message that replaced Fbi’s seizure of the confiscated websites comes after a similar action initiated earlier this year by the European authorities that resulted in the seizure of webstresser.org, a major DdoS service provider allegedly responsible for more than six million DdoS attacks. Nonetheless, the internet and the infrastructure that supports its function are still not secure, but the absence of some of the biggest players in this challenging area ensures that the DdoS attacks will be smaller in size and power and therefore more manageable.
