Jay Matthew Riley, 21, from Woodbridge, Virginia, had an alarming pop-up on his computer. The warning message claimed to be from the FBI and accused him of child pornography crimes. The message was displayed by all-too-commonly encountered ransomware, which locks victims computers and displays distressing messages about child sexual abuse in an attempt to trick computer owners into paying money. Instead of paying the fine, Riley took his computer to his local police station, and asked them if the message was legitimate. He was charged with three counts of possessing illegal images and indecent liberties with a minor.”]
