Emergency computers in Guilford County, NC were exposed for an unknown length of time because the server managing system updates was publicly available on the internet. The problem was discovered earlier this month by a researcher scanning the internet for exposed Rsync servers. A malicious actor could upload corrupted or blank files in place of the real ones, triggering system crashes that could have serious physical consequences to the 507,000 people who live in the county. The county said that the files on the server were read-only, which Vickery couldn’t confirm as doing so would place him in legal hot water.”]
