Eddie Raymond Tipton, former security director for the Multi-State Lottery Association in the US, was arrested in January on suspicion of hacking the computer system used to generate random winning numbers. Prosecutors say that there is CCTV footage of him purchasing the still unclaimed winning ticket.
Tipton is suspected of inserting a USB drive into a highly secure computer that picks the winning numbers. Although this system is constantly monitored by video camera, it is believed that he used his position as head of security to change the camera settings so that he could slip into the room and insert the drive undetected.
The BBC reports that prosecutors argue that there was a rootkit on the USB which programmed the computer to pick certain numbers, which Tipton later bought the ticket for, and then erase itself.
A senior analyst at security company First Base said the allegations were plausible, but that the kit could leave traces on the infected machine if one knows where to look.
Regulations mean that Tipton would not be allowed to win as an employee at the organisation.
