A new worm is currently circulating around the Web, masquerading as a simple shooting game.
According to a Sophos antivirus report, the worm - codenamed W32/Bibrog-B – is most likely to arrive by email with the following header:
Subject line: Fwd:La Academia Azteca
Message text: La cacademia azteca (muy bueno) no es virus!
Attached file: academia.exe
When the game is played, W32/Bibrog-B copies itself to other directories in order to propagate through email contacts, or file-sharing applications. The worm also attempts to take passwords and other personal information by loading 'dummy' versions of common Websites including Hotmail, Yahoo! and Citibank.
