Trojan:Win32/FormBook.SISN!MTB detection is a malware detection you can spectate in your computer. It generally appears after the preliminary activities on your PC – opening the untrustworthy email, clicking the banner in the Internet or setting up the program from suspicious sources. From the moment it shows up, you have a short time to act before it begins its harmful activity. And be sure – it is far better not to wait for these malicious effects.

What is Trojan:Win32/FormBook.SISN!MTB virus?

Trojan:Win32/FormBook.SISN!MTB is ransomware-type malware. It searches for the files on your computer, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this malware also does a ton of harm to your system. It changes the networking setups in order to stop you from checking out the elimination manuals or downloading the anti-malware program. Sometimes, Trojan:Win32/FormBook.SISN!MTB can even stop the setup of anti-malware programs.

Trojan:Win32/FormBook.SISN!MTB Summary

In total, Trojan:Win32/FormBook.SISN!MTB virus activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution;
  • Uses Windows utilities for basic functionality;
  • Reads data out of its own binary image;
  • 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;
  • Uses Windows utilities to create a scheduled task;
  • Detects Bochs through the presence of a registry key;
  • Checks the CPU name from registry, possibly for anti-virtualization;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the documents kept on the victim’s disk drive — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a headache for the last 4 years. It is challenging to imagine a more hazardous virus for both individual users and companies. The algorithms utilized in Trojan:Win32/FormBook.SISN!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. But that virus does not do all these horrible things immediately – it can require up to several hours to cipher all of your documents. Therefore, seeing the Trojan:Win32/FormBook.SISN!MTB detection is a clear signal that you have to start the removal process.

Where did I get the Trojan:Win32/FormBook.SISN!MTB?

Routine ways of Trojan:Win32/FormBook.SISN!MTB spreading are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free software, so-called bait emails and hacktools. Bait emails are a quite modern method in malware spreading – you receive the e-mail that imitates some routine notifications about shipments or bank service conditions shifts. Within the e-mail, there is a corrupted 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.

Avoiding it looks quite easy, however, still demands tons of focus. Malware can hide in various spots, and it is much better to prevent it even before it invades your PC than to rely on an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That can save you a lot of money and time which you would spend while seeking a fixing guide.
