The AA

According to a database leaked by Motherboard, an unprotected server included private data on over 100,000 AA users, frequently including partial credit card information.

The information obtained by Motherboard includes 117,000 distinct email addresses, along with full names, postal addresses, IP addresses, purchase information, and credit card numbers.

The credit card's last four digits and expiration date are included in that information.

According to security expert Scott Helme, the data also appears to contain a number of password hashes, an expired certificate, and a secret encryption key.
