Rekordstor ddos-attack uppmättes i juni

Den 27 juni i år inträffade en rekordstor ddos-attack, riktad mot ett kinesist telekomföretag. Det meddelar cybersäkerhetsbolaget Imperva, skriver sajten Bleeping Computer. Attacken pågick i drygt fyra timmar, och under den mest intensiva fasen gjordes 3,9 miljoner förfrågningar i sekunden. Snittet låg på 1,8 miljoner förfrågningar i sekunden, och totalt handlade det om 25,3 miljarder förfrågningar.

Redan dagen efter den rekordstora attacken genomfördes en ny attack mot samma företag, men den var inte lika kraftfull.

 
Denial-of-service attack (ddos-attack)
Wikipedia (en)
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate against this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources.A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge, blackmail and activism can motivate these attacks.
