Reports in a couple places about some really sneaky attacks if you do on-line banking. The attacks will steal your credit card info (with your help), make unauthorized charges, then remove those charges from your on-line statements. Pretty clever, actually.
Here’s a couple of links about this: http://redtape.msnbc.msn.com/_news/2012/01/06/9986119-new-virus-raids-your-bank-account-but-you-wont-notice and http://nakedsecurity.sophos.com/2012/01/05/spyeye-bank-trojan-hides-its-fraud-footprint/ .
Your defense? Those four things we mentioned here http://cellarweb.com/securitydawg/?p=56 : Windows updates, application updates, anti-virus updates, not browsing as an administrator. Those would be a great start.
