Those are one-day landing web pages where users are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite new strategy in malware spreading – you receive the email that imitates some normal notifications about shippings or bank service conditions modifications. Inside of the email, there is an infected MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly simple, however, still requires a lot of recognition.

Simple cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of money and time which you would certainly spend while searching for a fix guide.
