Ukrainian officials say Russian hackers targeted counter-intelligence and law enforcement data during the first half of this year.

Russia is pivoting from disruptive cyberattacks to more targeted operations aimed at giving it an advantage on the Ukrainian battlefield.

Researches believe the destructive malware is the work of Sandworm, a Russian military unit suspected in a series of Ukrainian cyberattacks.

Researchers at Microsoft said a ransomware attack on transportation and logistics companies was the work of Russian military intelligence

Moscow's approach to incorporating cyberattacks into its ongoing assault reflects an "absence of strategy," said Victor Zhora.

Expect to see more attacks, Microsoft says.

The State Department is offering $10 million for the location of six Russian intelligence officers in the Sandworm unit.

Russian losses near Kyiv and a looming onslaught in eastern Ukraine may be a factor in the attack, a Ukrainian official said.

The Department of Justice and FBI announced they used remote access technology to shut down a Sandworm botnet.

The botnet was being assembled by Russia's foreign intelligence agency, the GRU, Attorney General Merrick Garland said at a news conference.
