A county sheriff’s office in Tennessee paid a $500 ransom in bitcoin after it became the victim of a cyberattack this week.
Cryptowall is a Trojan horse program that, once inside a computer, encrypts its contents and triggers demands for a payment in bitcoin. The firm’s estimates suggest that after being discovered earlier this year, as many as 1,000 computers have been infected.
Detective and sheriff’s office IT director Jeff McCliss told WTVF-TV that a data cache containing sensitive documents, photographs and criminal reports was impacted. Overall, more than 70,000 files were temporarily inaccessible due to the malware infection.
