Ransom:Win32/BlueLocker.MK!MTB detection is a malware detection you can spectate in your computer. It often appears after the preliminary procedures on your computer – opening the untrustworthy e-mail messages, clicking the banner in the Internet or mounting the program from untrustworthy resources.

What is Ransom:Win32/BlueLocker.MK!MTB virus?

Ransom:Win32/BlueLocker.MK!MTB is ransomware-type malware. It searches for the documents on your disk, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this virus also does a lot of damage to your system. It modifies the networking settings in order to prevent you from checking out the removal guidelines or downloading the antivirus. In rare cases, Ransom:Win32/BlueLocker.MK!MTB can also block the launching of anti-malware programs.

Ransom:Win32/BlueLocker.MK!MTB Summary

Summarizingly, Ransom:Win32/BlueLocker.MK!MTB virus activities in the infected system are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;

Ransomware has actually been a headache for the last 4 years. It is difficult to picture a more damaging virus for both individuals and companies. The algorithms utilized in Ransom:Win32/BlueLocker.MK!MTB (typically, 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 immediately – it can require up to several hours to cipher all of your files. Hence, seeing the Ransom:Win32/BlueLocker.MK!MTB detection is a clear signal that you must start the clearing procedure.

Where did I get the Ransom:Win32/BlueLocker.MK!MTB?

Common methods of Ransom:Win32/BlueLocker.MK!MTB spreading are usual for all other ransomware examples. Those are one-day landing sites where users are offered to download the free program, so-called bait emails and hacktools. Bait emails are a relatively new method in malware distribution – you get the e-mail that imitates some routine notifications about shipments or bank service conditions modifications. Within the e-mail, there is a corrupted 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.

Preventing it looks fairly simple, but still demands tons of focus. Malware can hide in different places, and it is far better to prevent it even before it gets into your PC than to rely on an anti-malware program. Essential cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That can save you a great deal of money and time which you would certainly spend while searching for a fixing guide.
