The technology provider Kaseya, represented by Willkie Farr & Gallagher, cooperated extensively with the U.S. Justice Department and FBI following a cyberattack earlier this year, earning praise from DOJ officials who held up the company as a ransomware success story.

After Kaseya, a multinational software company, was attacked in July, the company almost immediately reported the breach to the FBI, Justice Department officials said, leading to the arrest of a Ukrainian man, Yaroslav Vasinskyi, accused of spearheading that attack and others that victimized people and businesses around the world.
