What is TrojanDownloader:Win32/Runner.SIB!MTB virus?

TrojanDownloader:Win32/Runner.SIB!MTB is ransomware-type malware. It looks for the files on your disk drives, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this malware additionally does a ton of harm to your system.

In rare cases, TrojanDownloader:Win32/Runner.SIB!MTB can even prevent the launching of anti-malware programs.

TrojanDownloader:Win32/Runner.SIB!MTB Summary

In total, TrojanDownloader:Win32/Runner.SIB!MTB malware activities in the infected computer are next:

  • Executed a very long command line or script command which may be indicative of chained commands or obfuscation;
  • Authenticode signature is invalid;
  • CAPE detected the Lu0BotLoader malware family;
  • A script or command line contains a long continuous string indicative of obfuscation;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;

  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a horror story for the last 4 years. It is hard to imagine a more hazardous malware for both individuals and organizations. The algorithms used in TrojanDownloader:Win32/Runner.SIB!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these bad things instantly – it may take up to several hours to cipher all of your files. Thus, seeing the TrojanDownloader:Win32/Runner.SIB!MTB detection is a clear signal that you must start the removal process.

Where did I get the TrojanDownloader:Win32/Runner.SIB!MTB?

General ways of TrojanDownloader:Win32/Runner.SIB!MTB spreading are usual 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 relatively modern strategy in malware spreading – you get the email that imitates some normal notifications about shipments or bank service conditions changes. Within the email, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks pretty easy, but still needs tons of recognition. Malware can hide in different places, and it is far better to stop it even before it gets into your PC than to rely upon an anti-malware program. General cybersecurity awareness is just an important item in the modern world, even if your interaction with a computer remains on YouTube videos. That can keep you a great deal of time and money which you would certainly spend while trying to find a fixing guide.
