What is Kut ransomware?

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.

How to prevent from getting ransomware

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.
