Where did I get the Ransom:Win32/StopCrypt.PBO!MTB?

Usual methods of Ransom:Win32/StopCrypt.PBO!MTB spreading are usual for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a quite modern method in malware distribution – you get the e-mail that imitates some regular notifications about deliveries or bank service conditions modifications. Inside of the e-mail, there is a corrupted MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks fairly easy, but still needs a lot of awareness.

Common cybersecurity awareness is just an important thing in the modern world, even if your interaction with a PC stays on YouTube videos. That can keep you a lot of money and time which you would certainly spend while trying to find a solution.
