“A police station in Dallas lost digital evidence, such as videos and photos, when it cleaned up from a ransomware attack after deciding not to pay. The Cockrell Hill Police Department’s servers were infected Dec. 12 by a ransomware virus that demanded $4,000 in bitcoins. The department, after consulting with the FBI cyber crime unit, opted not to pay the ransom and wiped the servers, according to a department statement.”
