Turkey's information infrastructure has been crippled by what security experts are calling the most intense cyber attacks the nation has ever weathered -- and now they know who's responsible.
After experts said the attacks originated from "organized sources" outside of the country, hacker collective Anonymous stepped forward to claim responsibility on Dec. 23, saying its members are attacking Turkey's critical information infrastructure and will continue to do so because of the country's alleged support for ISIS, Reuters reported.
"Turkey is supporting Daesh [ISIS] by buying oil from them, and hospitalizing their fighters. We won’t accept that [President Recep Tayyip] Erdogan, the leader of Turkey, will help [ISIS] any longer,” Anonymous said.
“We will continue attacking your Internet, your root DNS, your banks and take your government sites down,” the political hacktivist group warned. “After the root DNS, we will start to hit your airports, military assets and private state connections. We will destroy your critical banking infrastructure."
Anonymous claimed credit for the cyber attacks in a video, in which a member wore one of the group's signature Guy Fawkes masks while issuing threats to Turkey.
The sustained attacks have already crippled the servers behind around 300,000 Turkish websites, according to Reuters, targeting banking, government and military sites. Most of the attacks are distributed denial of service attacks, a method that cripples target servers by sending a flood of internet protocol packets. DDoS attacks can crash targeted servers, or render them unavailable for regular users.
These attacks can also do more than inconvenience users, and could cause significant monetary damage if commercial and market servers are disabled or crashed.
The allegations by Anonymous mirror accusations by Russian President Vladimir Putin, who accused Turkey and Erdogan of supporting ISIS after a Nov. 24 incident in which the Turkish military destroyed a Russian fighter jet. The Russian Su-24 had been participating in airstrikes against the terrorist group, and the incident sparked worries about further conflict in the region.
The attacks on Turkish digital infrastructure are not the first time Anonymous has set its sights on ISIS. The group announced a vigilante "cyber war" against ISIS in the wake of the Nov. 13 Paris terrorist attacks, which killed 129 people.
Anonymous also celebrated what it called a "Trolling Day" on Dec. 11, targeting "Daeshbags" and their social media accounts, The Independent reported.
The group ended its latest video with an ominous statement directed at Turkish leaders.
"Stop this insanity now, Turkey," a masked man said. "Your fate is in your own hands."
