Ukraine hit by more cyberattacks, destructive malware

Ukraine's parliament and other government and banking websites were hit with another punishing wave of distributed-denial-of-service attacks Wednesday, and cybersecurity researchers said unidentified attackers had also infected hundreds of computers with destructive malware.

Some of the infected computers were in neighboring Latvia and Lithuania, the researchers said.

Early Thursday local time in Ukraine, as fears of a Russian invasion heightened, the foreign ministry and council of ministers were unreachable and other sites were slow to load, suggesting the DDoS attacks were continuing, though there was no official confirmation.

Officials have long expected cyber attacks to precede and accompany any Russian military incursion, and analysts said the activity hewed to Russia's playbook of wedding cyber operations with real-world aggression.

ESET Research Labs said it detected a previously unseen piece of data-wiping malware Wednesday on "hundreds of machines in the country." It was not clear how many networks were affected.
