According to local news provider KARK, local businesses in Conway, Arkansas, have been hit with a ransomware attack. Some of the businesses have reportedly lost thousands of dollars.

Companies impacted by the attack don’t want to go public, but KARK is reporting that multiple files have been encrypted by hackers who are demanding a ransom in exchange for the returned files. Meanwhile, Brian Fletcher, owner of Fixed by Fletcher, a local IT company, has been speaking out to try and help others prevent or recover from an attack.

One of Fletcher’s customers, whom he declined to identify, was down for a couple days after falling victim to an attack despite efforts to recover documents from its four backups.
