Those are one-day landing sites where users are offered to download the free app, so-called bait emails and hacktools.

Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks pretty easy, however, still requires a lot of attention.

Basic cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a PC remains on YouTube videos.
