Thousands of US Air Force records, including highly private personnel data on senior and high-ranking commanders exposed due to an unprotected backup disc.
The compromised data includes personal information, such as names and addresses, ranks, and Social Security numbers of more than 4,000 officers. Another file lists the security clearance levels of hundreds of other officers, some of whom possess "top secret" clearance, and access to the sensitive compartmented information and codeword-level clearance.
The internet-connected backup drive's lack of a password made the gigabytes of files accessible to everyone, according to security researchers.
