What is Ransom:Win32/StopCrypt.SI!MTB virus?

Ransom:Win32/StopCrypt.SI!MTB Summary

Summarizingly, Ransom:Win32/StopCrypt.SI!MTB ransomware actions in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the RedLine malware family;

Ransomware has been a headache for the last 4 years. It is hard to picture a more harmful virus for both individual users and companies. The algorithms used in Ransom:Win32/StopCrypt.SI!MTB (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these bad things instantly – it can take up to a few hours to cipher all of your documents. Therefore, seeing the Ransom:Win32/StopCrypt.SI!MTB detection is a clear signal that you should begin the removal process.

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

Ordinary methods of Ransom:Win32/StopCrypt.SI!MTB injection are standard for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new strategy in malware distribution – you receive the e-mail that mimics some normal notifications about shipments or bank service conditions changes. Within the email, there is an infected MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly simple, but still requires tons of focus. Malware can hide in different spots, and it is much better to prevent it even before it invades your PC than to rely upon an anti-malware program. Simple cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can save you a great deal of time and money which you would spend while looking for a solution.
