Ransomware has been a major problem for the last 4 years. It is challenging to realize a more dangerous virus for both individuals and organizations. The algorithms used in Ransom:Win32/StopCrypt.PAD!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. But that virus does not do all these bad things without delay – it can take up to several hours to cipher all of your files. Hence, seeing the Ransom:Win32/StopCrypt.PAD!MTB detection is a clear signal that you should start the elimination procedure.

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

General ways of Ransom:Win32/StopCrypt.PAD!MTB distribution are basic for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a pretty new strategy in malware distribution – you get the e-mail that imitates some normal notifications about shippings or bank service conditions updates. Within the email, there is an infected MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks fairly simple, however, still needs a lot of attention. Malware can hide in different places, and it is better to prevent it even before it gets into your system than to depend on an anti-malware program. Simple cybersecurity awareness is just an important item in the modern world, even if your interaction with a computer stays on YouTube videos. That may keep you a great deal of time and money which you would spend while trying to find a fix guide.
