The CIA concluded that Russian military hackers were responsible for a cyberattack that disabled computers in Ukraine last year, The Washington Post’s Ellen Nakashima reports, citing U.S. intelligence officials referencing a classified report.

Why it matters: Experts believe Russia is using Ukraine as a testing ground for future cyberattacks, so the way it behaves in Ukraine is worth watching. The tactic here is notable as well: the hackers launched the attack using what appeared to be ransomware, which would make it appear is if they were criminal hackers.
