Ransom:Win32/StopCrypt.PAC!MTB Summary

In summary, Ransom:Win32/StopCrypt.PAC!MTB virus activities in the infected system are next:

  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Ciphering the documents located on the target’s disk drive — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware apps

Ransomware has actually been a major problem for the last 4 years. It is difficult to realize a more hazardous malware for both individuals and organizations. The algorithms utilized in Ransom:Win32/StopCrypt.PAC!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 already exists, and possibly will exist. However, that virus does not do all these unpleasant things instantly – it may require up to a few hours to cipher all of your documents. Thus, seeing the Ransom:Win32/StopCrypt.PAC!MTB detection is a clear signal that you should start the elimination process.

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

Ordinary tactics of Ransom:Win32/StopCrypt.PAC!MTB injection are common for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern method in malware distribution – you receive the e-mail that imitates some regular notifications about deliveries or bank service conditions modifications. Inside of the email, there is an infected MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks pretty easy, however, still requires a lot of recognition. Malware can hide in various places, and it is better to stop it even before it goes into your PC than to rely on an anti-malware program. Essential cybersecurity awareness is just an important item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may keep you a great deal of money and time which you would spend while seeking a fixing guide.
