Heartbleed bug: What you need to know (FAQ)

The vulnerability lets a hacker access up to 64 kilobytes of server memory, but perform the attack over and over again to get lots of information. That means an attacker could get not just usernames and passwords, but also "cookie" data that Web servers and browsers use to track individuals and ease log-in. According to the Electronic Frontier Foundation, doing the attack repeatedly could yield more serious information, like a site's private SSL key, used to encrypt traffic. With that key, someone could run a fake version of a Web site and use it to steal all other kinds of information, like credit card numbers or private messages.
