It seems that Evernote is the latest of the large sites to be hacked and this one is a major breach. Evernote says that all usernames and passwords were stolen from their servers.
And while those passwords and user names were encrypted they are requiring that all passwords be reset as an additional precaution against unauthorized access to user accounts.
So if you use or have an Evernote account get over there and reset your password ASAP. And look for and install the updates Evernote will be releasing over the next day or two.
Lets not let this breach become worse than it already is.
