All you need to know about Killnet ransomware

Killnet ransomware is a malicious computer virus designed to take files stored on a computer hostage. Differently than other existing ransomware, the Killnet hacktivist group seems to have created this threat solely to wreak havoc. After encrypting a file, the virus appends .killnet extension to its name before moving on to the next file. To explain it more graphically, files that were previously stored as 1.jpeg, 2.png, and 3.jpg automatically became 1.jpeg.killnet, 2.png.killnet and 3.jpg.killnet respectively.

Having completed this first stage, the ransomware then creates a ransom note in Russian (Ru.txt), however, the note doesn’t demand a ransom payment. In addition to that, Killnet ransomware virus also removes the existing desktop wallpaper. However, the image it eventually replaces it with will depend on the particular ransomware version that infected the computer.

Further details about the virus

The purpose of the ransom note is to bring the victim up to speed about the Killnet ransomware virus attack. Instead of traditional email addresses that are usually left in various ransomware notes, the criminals behind this malware choose to leave Telegram account usernames instead. At the end of the message, they will include a pro-Russian solidarity closing remark.

Generally, ransomware viruses are developed by online rogues with the intention of seizing control of other people’s data in order to extort fees from them. Over the years, we have been able to monitor a series of ransomware viruses and how they encrypt data. Following our extensive research, we came to the conclusion that it is extremely difficult, if not impossible, to reverse encryption without the involvement of those behind the attack. In fact, the best way to avoid being extorted is to always keep a data backup on an external data storage device.

To make matters even worse for those at the receiving end, paying a ransom fee to the cybercriminals is not a guarantee that decryption tools will be sent to them as promised. In other words, it becomes a double loss to the victim. Because of that, victims are strongly advised never to comply with the demands of cybercriminals. It is also important to note that paying ransom fees to cybercriminals encourages them to continue constituting a nuisance. Therefore, the only way to ensure that cybercriminals are defeated is to completely stop ransom payments. However, in this case, the cybercriminals do not demand a ransom, which implies that the virus is developed and distributed with sole intention to cause harm and corrupt user files.

We advise computer users to remove Killnet ransomware virus without further delay in order to salvage other files that are yet to be encrypted. Also, removing it on time will enable the victim to commence retrieval efforts soon enough. The only viable way to recover such damaged files is by making use of your backup device. That is why we always emphasize on the importance of keeping a backup at all times. They could be in the form of unplugged storage devices kept in different locations and remote servers etc. Such backups can come handy after experiencing a ransomware virus attack.

Our team advises investing in a trustworthy antivirus solution to keep further cyberattacks at bay. Our top pick in AV industry at the moment is INTEGO Antivirus, which we have extensively described in this review.

About the Killnet hacktivist group

Killnet is a pro-Russian hacktivist group that is mostly known for their unsophisticated DDOS attacks and regular and despicable statements about NATO in their Telegram channels. The collective says their targets are anyone who supports Ukraine. The group has multiple Telegram channels just like those listed in the ransom note, where they find a medium to ramble and spread misinformation about the war and politics in general.

How ransomware infects computers

Different types of malware, including ransomware viruses, are often spread via phishing and other social engineering tactics that are deceptive in nature. The cybercriminals that create them usually bundle them together with cloned software content. Such compromised files can be in diverse forms such as executables (including .exe), archives (including RAR and ZIP, etc.), JavaScript, PDF, and Microsoft Office documents, among similar others. Once a user opens an infected file in their computer, it triggers a ransomware attack.

Cybercriminals use diverse distribution methods to spread malware. Still, the common ones are deceptive drive-by downloads, malware embedded in emails and attachments, online scams, online torrent platforms, P2P sharing networks, illegal program activation (“cracks” and fake tools), fake updates, etc.

How to effectively safeguard computers against ransomware virus infections

As you can see from the list of malware distribution channels highlighted above, illegal software downloads should be shunned. Those in need of software programs should go to the official pages of the brand’s copyright owners or their authorized distribution partners to source for it. Also, trying to use “cracks” or cloned versions of software copies is risky and should be avoided entirely.

Additionally, emails and accompanying attachments that land in your inbox should always be inspected in a cautious manner. You should consider if the email is related to you or your activities. Is the originating address genuine or spoofed? If otherwise, please avoid opening the accompanying links/attachments because doing so could result in system infections.

It is crucial to install genuine antivirus from recognizable brands on your computer and keep it updated. Therefore, it is necessary to perform regular scans so that possible threats can be detected in a timely manner and removed.
