Heartbleed is a flaw in OpenSSL, the open-source encryption standard used by the majority of websites that need to transmit the data that users want to keep secure. It basically gives you a secure line when you're sending an email or chatting on IM. Occasionally, one computer might want to check that there's still a computer at the end of its secure connection, and it will send out what's known as a heartbeat, a small packet of data that asks for a response. Because of a programming error in the implementation of OpenSSL, the researchers found that it was possible to send a well-disguised packet of data that looked like one of these heartbeats to trick the computer at the other end into sending data stored in its memory.
