Schneier on Heartbleed  10 April 2014 
Source: Schneier on Security - Posted by Dave Wreski   
Basically, an attacker can grab 64K of memory from a server. The attack leaves no trace, and can be done multiple times to grab a different random 64K of memory. This means that anything in memory -- SSL private keys, user keys, anything -- is vulnerable. And you have to assume that it is all compromised. All of it.

Many of the websites you use at home and in the office are vulnerable to hacking, according to researchers who uncovered a security flaw in OpenSSL, the open-source software that is used to encrypt online communications. Websites and apps that encrypt data with a password likely use OpenSSL, and the cryptographic library is used to secure the servers that work with more than 66 percent of active websites on the Internet.

It's already possible to make some inferences about the appearance of crime suspects from their DNA alone, including their racial ancestry and some shades of hair colour. And in 2012, a team led by Manfred Kayser of Erasmus University Medical Center in Rotterdam, the Netherlands, identified five genetic variants with detectable effects on facial shape.
