Hackers launched a “large-scale cyberattack” on the website of the European Court of Human Rights after it published a ruling critical of Turkey.
The tribunal said the attack followed its 22 December order for Turkey to immediately release Selahattin Demirtas, a former leader of the pro-Kurdish HDP party. The court website was offline for around 16 hours starting Tuesday, a spokesperson said. The website and the ruling could be accessed on Wednesday.
Bloomberg was unable to independently verify the authenticity of the hackers’ official Twitter account or their claim for responsibility for cyberattacks. The Twitter handle purportedly used by the group was established earlier this month and had 97 followers by early Wednesday.
A website named after the hacker group said their aim is to pursue interest of the Turkish nation and the religion of Islam without any financial gain.
The court rules on violations of a human rights convention signed by more than 40 countries, including Russia and Turkey. Located in Strasbourg, France, it has rebuked Turkey over recent detentions and criticised Moscow over its treatment of opposition leader Alexey Navalny and businessman Mikhail Khordorkovsky.
U.S. government agencies were attacked this year as part of a global campaign orchestrated by hackers believed to be tied to the Russian government, according to U.S. officials. The hackers were reported to have installed a malicious vulnerability in software from Texas-based SolarWinds Corp., whose customers include top government agencies and Fortune 500 companies.
