Cyberattacks Knock Out Sites of Ukrainian Army, Major Banks

Summary:

A series of cyberattacks knocked out the websites of the Ukrainian army, the defense ministry, and major banks offline, Ukrainian authorities said, as tensions persisted over the threat of a possible Russian invasion. Still, there was no indication the relatively low-level, distributed-denial-of-service attacks might be a smokescreen for more serious and damaging cyber mischief. At least 10 Ukrainian websites were unreachable because of the attacks, including the defense, foreign, and culture ministries and Ukraine’s two largest state banks. In such attacks, websites are barraged with a flood of junk data packets, rendering them unreachable.
