Sudoku and malware with your coffee?

JB

As the end of the year approaches and things calm down around the office, what better way to while away a few minutes than with a harmless Sudoku?

Perhaps not so harmless if it's the Microsoft Excel based Sudoku generator spreadsheet that arrived in SophosLabs recently.

This spreadsheet hides a nasty secret: it contains malware.

However, rather than rely on a vulnerability to install the malware, it uses sleight-of-hand instead.

Microsoft Office includes the powerful programing language Visual Basic for Applications, accessible from Office documents as macros.
