At least 15 websites belonging to various Ukrainian public institutions were compromised, defaced, and taken offline. The websites of the ministry of foreign affairs, agriculture, education and science, security and defense, and the online portal for the cabinet of ministers are temporarily down. The Ukrainian cyber-police has also posted an announcement where they underline that no personal data was compromised due to these attacks and that the warning messages to visitors were false and only meant to scare citizens. Researchers theorize that the attacks could have been conducted by the GhostWriter APT hacking group, which has a history of targeting government entities in Poland and Ukraine.”]
