Those are one-day landing sites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively modern method in malware distribution – you receive the e-mail that imitates some standard notifications about shippings or bank service conditions updates. Inside of the e-mail, there is an infected MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite easy, but still demands tons of focus. Malware can hide in various places, and it is much better to stop it even before it gets into your computer than to rely on an anti-malware program. Essential cybersecurity awareness is just an essential thing in the modern world, even if your interaction with a PC stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while searching for a solution.
