A trio of Alabama hospitals have decided to pay for a decryption key.

An Alabama hospital system has paid its attackers in a ransomware attack that knocked its systems offline on Oct. 1.

Officials at the DCH Health System didn’t say how much the hospitals paid for the decryption key, but noted that they have started a “methodical” process of system restoration.

“We have been using our own DCH backup files to rebuild certain system components, and we have obtained a decryption key from the attacker to restore access to locked systems,” according to a website notice.
