As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself.
If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft.
This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.
