According to the Times, "the websites of many of Ukraine's institutions, including Parliament, the Foreign Ministry and the cabinet of ministers, were brought down by a distributed denial-of-service attack, known as DDoS," and several of the sites remained down by Wednesday evening.
Last week, hackers targeted the Ukrainian military and the country's two largest banks. Russia denied responsibility for the attacks.
In January, Microsoft detected a dangerous malware infection in dozens of government and private Ukrainian computer networks. Ukrainian officials said at the time they had evidence linking the attacks to Russia, but a Kremlin spokesperson accused Ukraine of "blaming everything on Russia."
