http://www.theregister.co.uk/2014/10/14/google_drops_ssl_30_poodle_vulnerability/As warned by The Register, security researchers have discovered a vulnerability in SSL 3.0 that allows attackers to decrypt encrypted connections to websites.
Miscreants can exploit a weakness in the protocol's design to grab victims' session cookies, which are used for logging into webmail and other online accounts over HTTPS.
The attack is, we're told, easy to perform, and can be done on-the-fly using JavaScript – provided you can intercept the victim's packets, perhaps by setting up a malicious Wi-Fi point in a cafe or bar.
