Ransomware has been a nightmare for the last 4 years. It is hard to imagine a more harmful virus for both individual users and businesses. The algorithms utilized in Ransom:Win32/StopCrypt.PBT!MTB (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these unpleasant things without delay – it may take up to several hours to cipher all of your files. Therefore, seeing the Ransom:Win32/StopCrypt.PBT!MTB detection is a clear signal that you need to begin the removal procedure.

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

General methods of Ransom:Win32/StopCrypt.PBT!MTB spreading are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern tactic in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions updates. Inside of the email, 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.

Preventing it looks pretty uncomplicated, however, still needs a lot of recognition. Malware can hide in different spots, and it is much better to prevent it even before it invades your system than to depend on an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern world, even if your relationship with a computer stays on YouTube videos. That can keep you a lot of money and time which you would certainly spend while looking for a solution.
