Not worried. They have no indication of having been hacked. If they were hacked (IF IF IF IF IF!), stronger passwords will take a hacker longer to crack. If you haven't been asked to change your password, you should be fine. Read the LastPass blog, and don't worry about the media trolls. I have confidence in a service that takes an "anomaly" so seriously. What they learn from this event will make them even better, security-wise and in how they handle it. - Allison Kipta from Bookmarklet
