The infamous Zeus malware has once again resurfaced as per Symantec and is capable of draining your bank accounts. The program is sophisticated enough that it can replace a bank’s Web site with a mimicked page of its very own. The fake page can then ask for social security number information and other data that is then sold on the black market. Facebook is aware of the rising issue, but does not appear to be taking much action on it. The virus is said to specifically target Windows devices and will not work on Mac OS X or Linux.
