Kut ransomware – a dangerous cryptovirus from Dharma family

Kut ransomwareKut ransomware is a data locking computer infection that belongs to Dharma family

Kut ransomware is a cryptovirus that, if not detected and isolated by proper anti-malware software, will lock victims' personal files, and a ransom will be required to decrypt them. Kut virus derives from the Dharma ransomware family. When an infectious file enters the computer system, it immediately starts the encryption[1] process. All non-system files are encoded, appended with three extensions (prescribed user ID, criminal contact information, and .kut), and made unavailable to the victim. As soon as this process is completed, ransom notes (FILES ENCRYPTED.txt) are placed in affected folders with instructions on what to do to regain access to the encrypted data. Also, an abrupt pop-up window with the same guidelines presents itself.

In both ransom notes, the cybercriminals briefly explain that the files are locked and threaten the victims not to try and rename or try and unlock the files with third-party decryption tools, as this may lead to permanent data loss. Two contact emails are provided – kuk1@tuta.io, ti7s@protonmail.ch. According to the perpetrators, the second email should be used only if a victim of their cybercrime doesn't receive an answer within 12 hours of made contact. Developers of Kut ransomware don't provide any more details about the ransom, nor the amount not the requested means of payment.

Methods cybercriminals use to infect victims' devices

Ransomware and other similar malware is spread out on the internet and is waiting for a vulnerable computer to download it. Most infections occur while downloading contaminated email attachments, opening mischievous hyperlinks that lead to malicious content, initializing torrents.

Developers of various malware conduct so-called “spam campaigns,”[3] during which they send out thousands of emails to recipients all over the world. Within these emails are either infected attachments or misleading hyperlinks. Upon clicking on either of them, a payload file is downloaded to users' devices, and pollution of the computer begins. Prior to retrieving any file from the mailbox, users should scan it with powerful anti-malware software to make sure the desired file is virus-free.

Torrent sites like BitTorrent, The Pirate Bay, and alike are another sure way to get some infections in the computer system. Malware can be disguised as various file types, such as .pdf, .txt, .jpeg, etc. Once ransomware is in the device, it starts what it was created for – encryption and money extortion.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Kut from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Kut, you can use several methods to restore them:

Data Recovery Pro might come in handy

This tool can sometimes be used to partially recover locked .kut files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Kut ransomware;
  • Restore them.

Make use of Previous Windows Versions feature

This method can be used to restore files one-by-one, although it won't work if malware deleted automatic Windows backups.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

In some cases, ShadowExplorer can restore all locked files

If the virus failed to delete Shadow Copies, ShadowExplorer is one of the best tools you could use to recover your data.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No decryptor is currently available

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Kut and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
