Those are one-day landing sites where victims are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a pretty modern strategy in malware spreading – you receive the email that imitates some standard notifications about shipments or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty uncomplicated, however, still needs a lot of focus.

Common cybersecurity knowledge is just an essential thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while trying to find a solution.
