Ukraine’s Defense Ministry hit by DDoS in tense showdown with Russia

On Tuesday, Ukraine’s Defense Ministry suffered a DDoS attack that blocked users from accessing its website, and two Ukrainian banks lost access to online banking services, according to government statements.

In one Tweeter released around 7:00 p.m. local time (12:00 p.m. ET), the Ukrainian Ministry of Defense said its website was likely hit by a DDoS attack and work to restore service was underway. Four hours later, the site was still not accessible.
