Typical tactics of Ransom:Win32/ContiCrypt.CRP!MTB spreading are standard for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a pretty new method in malware spreading – you receive the e-mail that simulates some normal notifications about shippings or bank service conditions changes. Inside of the email, there is an infected MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks pretty easy, but still demands tons of awareness.

General cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a PC stays on YouTube videos. That may keep you a great deal of money and time which you would spend while looking for a fix guide.
