“A faulty backup has inadvertently exposed the entire working database of notorious spam operator River City Media (RCM). In all, the database contains more than 1.37 billion email addresses, and for some records there are additional details such as names, real-world addresses, and IP addresses. It’s a situation that’s described as “a tangible threat to online privacy and security.”
Details about the leak come courtesy of Chris Vickery from macOS security firm MacKeeper who — with a team of helpers — has been investigating since January. River City Media’s database ended up online thanks to incorrectly-configured Rsync backups. In the words of Vickery: “Chances are you, or at least someone you know, is affected.”
