4. be careful with file attachments
Have you ever received a reminder, invoice or order confirmation of things you never ordered? Then scammers are trying to get you to open a file attachment. Here, first check what file format it is. Very dangerous email attachments are: .exe, .bat. , .pif, .scr, .com, .cmd or even file formats of Microsoft’s Office products that contain macros. Warning: the misconception that you are “safe” if you open the mail via smartphone or tablet to check is not true nowadays! Android and iOS are also vulnerable via email and are the target of thousands of scammers.
