"A growing trend of politicized hacking or "hacktivism" is emerging. The incidents in Estonia and Georgia were most likely carried out by state-encouraged Russian nationalist youth groups and criminal organizations, as well as at-large volunteers. One German youth claimed on a web forum that, with instruction from a Russian website, he was initiating fully functional denial-of-service attacks against targets in Georgia in a manner of hours. In reaction to a Danish newspaper cartoon of the Prophet Mohammad, loose groups of hackers in Turkey and other Muslim countries cyberattacked that publication's website."
