Ransomware has actually been a major problem for the last 4 years. It is difficult to picture a more harmful malware for both individual users and businesses. The algorithms used in Ransom:Win32/Conti.SD!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. But that virus does not do all these unpleasant things immediately – it can require up to a few hours to cipher all of your files. Thus, seeing the Ransom:Win32/Conti.SD!MTB detection is a clear signal that you need to start the elimination process.

Where did I get the Ransom:Win32/Conti.SD!MTB?

General methods of Ransom:Win32/Conti.SD!MTB distribution are common for all other ransomware variants. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a quite modern tactic in malware spreading – you receive the email that mimics some normal notifications about shippings or bank service conditions changes. Within the e-mail, 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 simple, however, still requires a lot of attention. Malware can hide in different spots, and it is far better to stop it even before it goes into your PC than to trust in an anti-malware program. Standard cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can keep you a great deal of time and money which you would certainly spend while seeking a solution.
