BAT/KillBackup.C detection is a virus detection you can spectate in your system. It generally appears after the preliminary activities on your PC – opening the suspicious email, clicking the banner in the Web or mounting the program from suspicious resources. From the moment it appears, you have a short time to do something about it until it begins its harmful activity. And be sure – it is far better not to wait for these harmful things.

What is BAT/KillBackup.C virus?

BAT/KillBackup.C is ransomware-type malware. It looks for the files on your disk drives, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware also does a lot of harm to your system. It modifies the networking setups in order to stop you from checking out the elimination guidelines or downloading the anti-malware program. In some cases, BAT/KillBackup.C can additionally stop the setup of anti-malware programs.

BAT/KillBackup.C Summary

Summarizingly, BAT/KillBackup.C ransomware actions in the infected PC are next:

  • Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;
  • Uses Windows utilities to create a scheduled task;
  • Uses suspicious command line tools or Windows utilities;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Encrypting the documents located on the victim’s disk drives — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a headache for the last 4 years. It is challenging to imagine a more dangerous malware for both individual users and businesses. The algorithms utilized in BAT/KillBackup.C (generally, 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 actually exists, and possibly will exist. But that virus does not do all these horrible things immediately – it may require up to a few hours to cipher all of your files. Therefore, seeing the BAT/KillBackup.C detection is a clear signal that you need to begin the elimination process.

Where did I get the BAT/KillBackup.C?

Common ways of BAT/KillBackup.C spreading are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free software, so-called bait emails and hacktools. Bait emails are a relatively modern method in malware distribution – you receive the email that mimics some regular notifications about deliveries or bank service conditions changes. Within the e-mail, 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.

Avoiding it looks quite uncomplicated, however, still requires a lot of focus. Malware can hide in different places, and it is better to stop it even before it invades your PC than to trust in an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern 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 searching for a fixing guide.
