SSL/TLS man-in-the middle (MITM) vulnerability. What is it?
Researches have discovered a new vulnerability that allows attackers who are eavesdropping to intercept data between a client (an end user, like yourself) and a server (a network provider like us, your online banking provider, etc.) during the “handshake” that establishes secure connections. The attack forces the server to use weak encryption keys and can only be performed between a vulnerable client AND a vulnerable server (servers are only known to be vulnerable in OpenSSL 1.0.1 and 1.0.2-beta1).
How does it affect you?
An attacker can intercept, decrypt the data and alter the traffic sent between the client and server.
Was Hushmail affected?
No, traffic to Hushmail's web-servers was never vulnerable to this attack.
