Kvag ransomware – a form of malware that might use the TCP port 3389 for unexpected distribution

Kvag ransomware

Kvag ransomware is a malicious threat that can hack RDPs for placing itself on the targeted system. What happens next definitely is not a satisfying experience to have. Unfortunately, this malware belongs to the well-known Djvu threat family and is also rooted in the STOP ransomware category. Kvag virus seems to expand the family line by attacking random victims and locking their files with the .kvag appendix. After that, the _readme.txt message is yet to come and be inserted in every folder that holds encrypted documents and on the desktop also. If you have already read about Djvu-related malware, you might notice that ransom demand are always the same – $490 which is a 50% discount or $980 if victims do not contact the criminals in time (between three days). 

If you decide to pay the criminals who are responsible for pushing Kvag ransomware on your system, do not be surprised to receive anything at all, except for useless money loss. Scamming is often the major task of malware developers as they seek to gather as much income as possible by distributing their created threats. Be aware that the hackers provide the gorentos2@firemail.cc, gorentos@bitmessage.ch email addresses, and the @datarestore Telegram for contact.

Detection If you are looking for a tool that will help you to locate all malicious entries on your computer, try downloading and installing Reimage

Kvag ransomware is a nasty cyber threat to deal with because it carries many different activation modules inside its core. Besides just encrypting data and placing ransom demands to your case, the malware modifies directories such as the Windows Registry and Task Manager and leaves these sections filled with malicious components.

Usually, various bogus entries and keys allow Kvag ransomware to overrun antimalware detection and boot itself automatically every time when the infected machine is turned on by the user. This way the ransom-demanding threat ensures that its activities remain successful and bring benefits all the time.

In addition, Kvag ransomware modifies that hosts file and disables the users from visiting security-related websites where they might find professional help for defeating the ransomware virus. However, if you find out that your hosts file has been changed or damaged, you should delete it from this directory on your Windows computer: C:\Windows\System32\drivers\etc.

Nevertheless, the Shadow Volume Copies of your encrypted data also remain unsafe while Kvag ransomware is residing on your machine. The cyber threat makes sure that these components are eliminated and you are not able to recover your documents and files without purchasing the decryptor from the crooks themselves. Hackers state in the ransom note that data can be reversed only with their tool:

Even though Kvag ransomware remains undecryptable at the moment, there is no need to rush and pay the crooks as they might easily scam you and just steal your money. As an alternative, we recommend trying the Rescue Pack that is offered by DrWeb. The package includes a data recovery option and 2 years of automatical computer protection.

Last but not least, malware strains that come from the STOP ransomware family are capable of carrying banking malware such as the AZORult trojan and Kvag ransomware is not an exception. If you end up with the additional threat on your system, you might suffer from money swindling and personal data theft.

Avoid all these risks by performing the Kvag ransomware removal task. However, note that no manual elimination techniques are acceptable in this case as they are too ineffective and dangerous to perform. Do not take any more risks and get a reliable antivirus program to locate the malware on your computer and remove it without causing more damage.

Besides, if you are looking for a tool that will lengthen the termination process, our offer would be to install a program such as Reimage. Afterward, launch this software and wait until it completes a full system scan. After a while, you will be provided with a list of all malicious objects found that will create a better view from where the antimalware needs to remove Kvag ransomware.

The most common distribution ways that are used by ransomware developers

According to various Internet sources, ransomware developers often misuse RDPs for injecting their beloved threats into the targeted machines. One of the most commonly used ports is the TCP port 3389 which is hacked and then the password is pushed in under the victim's own will.

In addition, this is not the only way how particular ransomware strains might end up on your computer system. You might also receive some reputable-looking but fake email messages from various shipping organizations such as FedEx that ask to confirm your order. If you press on the confirmation link, the ransomware will be loaded on your computer.

Besides, the malicious payload can come delivered in attachments such as JavaScript files, ZIP, RAR, Word, Excel, or PowerPoint files. The criminals might think of attaching a fake payment information message. So be aware that not everything that looks reliable is truly worth opening.

Continuously, ransomware-related content can be found on peer-to-peer networks, including The Pirate Bay. Here, software downloading hyperlinks are free and because of that, they come unprotected. By installing products from such networks, you take a risk of receiving malicious programs also.

Avoiding ransomware is necessary. Secure your computer with these steps

Technology experts claim that avoiding ransomware and other malware should be a necessity for every user. First of all, ensure that you have reputable antivirus protection working on your computer system. Make sure that you update your antimalware program once in a while.

Furthermore, always sort out your received email. If you have received a message from some type of a reputable organization but do not remember expecting any news lately, better contact the firm directly and ask about the email message. Also, always check the sender and avoid opening any bogus attachments/links.

Continuously, keep a distance from bogus downloading sources as cracked software might carry malicious programs. Besides, by activating a non-original downloading link, you might launch the ransomware straight to your computer system.

Data recovery possibilities for .kvag files that you should know about

Kvag ransomware is a currently undecryptable malware strain, so you might have some difficulties while trying to recover files and documents that have been touched by this malicious threat. While you are waiting for decryption tool updates, there are some things that you can try.

We have found out that DrWeb offers a specific Rescue Pack for $150. This includes a data restoring tool and 2 years of automatical system protection. The company claims that they allow the users to try recovering some files for free and if the tool works, they can purchase the Rescue Pack. Even if the free program does not work, the victims are not charged with any type of fee.

In addition, we have provided three data recovery options at the end of this article that you can also try. However, make sure that you use the automatical removal instructions before you begin with the file restoring process, otherwise, the cyber threat will just renew the encryption during the next computer boot.

The advanced removal process for Kvag ransomware

Kvag ransomware removal is a process to which you need to put all of your attention. However, first, we recommend scanning the entire system with a reputable program so that it will inform you about all the locations that have been touched by the ransomware virus. You can choose one of these tools: Reimage, SpyHunter 5Combo Cleaner, Malwarebytes.

After you remove Kvag ransomware from your Windows computer system, it is about time to think about the safety of your future data.
