When the user is vulnerable

[sumaiyakhatun26]

Macro attacks exploit perhaps the most dangerous vulnerability in cybersecurity: the human user. Lack of computer literacy and carelessness make users easy targets for hackers and allow criminals to anticipate user execution of their malicious package. Criminals have to trick users twice : first to convince them to download a file with a macro and then to allow the macro to run. There are various tactics that hackers can resort to, but they are mostly similar to most phishing and malware-spreading campaigns.

Macro security in current versions of Excel (2007 and later):
If you want to run macros in current versions of Excel, you need to save the Excel uk rcs data file as a macro-enabled workbook. Excel recognizes macro-enabled workbooks by the .xlsm file extension (instead of the more common .xlsx extension).

So, if you add a macro to a standard Excel workbook and want to be able to run this macro every time you access the workbook, you will need to save it with the .xlsm extension.

To do this, select Save As from the "File" tab of the Excel ribbon. Excel will then display the "Save As" screen or "Save As" dialog box.
