Microsoft: Many are the ones who at some point completely fell into a phishing campaign that caused errors on their PC. There are all sorts of them, but the ones that reach you through an email with an attachment are very dangerous. Especially the ones that seem the most harmless, because they can contain a serious problem inside. We are talking about the malware hidden in an Excel sheet that has an extra security to avoid it.
Microsoft is going to prevent secret malware in Excel
Excel is one of the most versatile tools in the entire Office 365 suite. Yes, it’s true that at first glance it looks more like a sheet to perform complex calculations, develop graphs or interactive lists than to efficiently transport a store’s inventory, for example. There are very specific functions that are very useful, such as macros, which can store a range of malware.
You might not believe it, but it’s been a common practice for years and all because of taking advantage of Excel 4.0 XLM macros. They could deliver a malicious program to the target computer, but now Microsoft will disable this feature by default. This assumes that users cannot use this feature unless they or the order administrator. This is not to say that macros are not activated, because Microsoft recommends people to use VBA macros.
