(Portland, OR) -- An Armenian man from Ukraine has pleaded guilty for his role in a ransomware cyberattack that targeted companies in the U.S., including an Oregon tech company. The Ryuk ransomware locked computers until companies paid ransom and then decryption keys were sent to unlock the systems. Under the plea deal, the man agrees to pay more than a million dollars restitution and faces another 250-thousand dollars in fines, along with up to 10 years in federal prison.
