The new malware is titled RAA and hides by assuming the form of a document, the opening of which triggers the encryption process. The problem with this approach, an alternative to the classic of sneakily downloading and installing the virus without anything from the user, is that people often open up emails and will, without a second thought, open an attachment.
You should always be careful with email attachments, only opening them if you are expecting the document and recognise its source. If you weren’t expecting the document then check with its sender what it is and if you or they can’t remember what it is, don’t open it.
