Trojan.Scar detection is a virus detection you can spectate in your system. It usually appears after the provoking procedures on your PC – opening the untrustworthy e-mail, clicking the banner in the Internet or installing the program from unreliable resources. From the second it shows up, you have a short time to take action until it begins its malicious action. And be sure – it is better not to wait for these destructive actions.

What is Trojan.Scar virus?

Trojan.Scar is ransomware-type malware. It looks for the documents on your computer, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware additionally does a lot of damage to your system. It alters the networking settings in order to avoid you from reading the removal tutorials or downloading the anti-malware program. Sometimes, Trojan.Scar can also block the launching of anti-malware programs.

Trojan.Scar Summary

Summarizingly, Trojan.Scar malware activities in the infected system are next:

  • Sample contains Overlay data;
  • Reads data out of its own binary image;
  • The binary contains an unknown PE section name indicative of packing;
  • The executable is compressed using UPX;
  • Authenticode signature is invalid;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the files kept on the victim’s disk — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • 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 dangerous malware for both individuals and organizations. The algorithms utilized in Trojan.Scar (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 unpleasant things without delay – it can take up to a few hours to cipher all of your files. Therefore, seeing the Trojan.Scar detection is a clear signal that you must start the clearing process.

Where did I get the Trojan.Scar?

Common methods of Trojan.Scar spreading are standard for all other ransomware examples. Those are one-day landing web pages where users 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 spreading – you receive the email that imitates some regular notifications about deliveries or bank service conditions shifts. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks pretty easy, but still requires a lot of attention. Malware can hide in various places, and it is far better to stop it even before it goes into your system than to rely upon an anti-malware program. Basic cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That may save you a lot of money and time which you would spend while searching for a fix guide.
