There's a serious and widespread vulnerability affecting the way most web sites and email servers encrypt communication for things like shopping and account login activities (anything involving web sites using HTTPS). The vulnerability is at the server itself and could allow hackers to get stored data like passwords or credit card numbers, but only if the server software is not up-to-date.
NetFu and our customer servers are up to date and test as not vulnerable.
