David Wilson reports:
Yuba County was recently the subject of a ransomware cyber-attack, which infected some of the county computer systems with malware, according to county spokesperson Russ Brown.
The malware encrypted the affected systems and the attacker demanded payment from the county in order to obtain a decryption key. The county did not make any payment to the attacker, according to Brown.
