Popular DDoS malware families we discovered in Underground
forums include DirtJumper, Darkness, and
Gbot. The prices for the DDoS malware kits ranged from
just under one thousand US dollars for the Darkness kit
to free pirated downloads of the DirtJumper kit. The cybercrime
ecosystem also provides so-called DDoS-forrent
services saving the customer the hurdle of maintaining
the necessary infrastructure.
