Police say they thwarted two waves of online attacks targeting Eurovision online voting. Authorities say the attempted disruption was launched by a pro-Russia attack group called “Killnet” Killnet, however, denies any allegations that it was involved in attempted disruption. The group also announced that it had “declared war” on Italy and nine other countries on its target list. Killnet appears to claim responsibility for the DDoS attack on Eurovision during the semifinal on Wednesday, and during the final on Saturday.”]
