Remove Kasp ransomware (Virus Removal Guide) - Decryption Methods Included

removal by Alice Woods - - | Type: Ransomware

Kasp ransomware is yet another version in the Djvu virus family that cannot be decrypted

Kasp ransomwareKasp ransomware - the threat that makes files inaccessible by encrypting them.

Kasp ransomware – a cryptovirus that adds .kasp file extension to pictures, documents, videos, and other data located on the compromised PC. Users[1] fill up online forums with questions about decryption and solutions to repair affected files and clear the infection. However, there are not many solutions available, since the virus employs powerful encryption[2] methods with the help of RSA cryptosystem – it ensures that files would require a unique key that is sent to cybercriminals' server, although they are not willing to provide it for free, as evident.

The identification ID is displayed in the ransom note file _readme.txt, which is dropped on various places on the system, as well as the desktop. The body text did not change for many versions so far – victims who get infected with OgdoGeno, and other variants will see an almost identical message from the Kasp ransomware virus creators; although contact emails this time are helpmanager@mail.ch and restoremanager@airmail.cc.

The note details the encryption impact on files and claims that the only option for the victim is paying a ransom of $980/$490. However, we do not recommend even contacting these people since criminals cannot be trusted. Remember that cryptocurrency extortionists are not focused on your belongings; they only want to make money from victims, so they might never provide the required Kast file virus decryption tool.

Name Kasp ransomware
Family Kasp virus is the version of Djvu ransomware that is coming from a family of STOP ransomware viruses
File appendix .kasp is the file extension that comes right after the original name of the file and file type indicating extensions. These marked files are encrypted and cannot be used nor opened without decryption
Ransom note _readme.txt – a file that is used to inform people about the virus behavior and possible solutions. However, criminals state that the only possible next step is paying the ransom of $980 or $490 in Bitcoin for the alleged decryption tool
Distribution The file encryption virus is spread using malicious files with ransomware payload. Such data is distributed via pirated file services, torrent sites, spam email campaigns. It is known that this virus family relies on fake Flash Updates and Adobe Photoshop cracks to inject systems with malicious ransomware payload
Fie recovery options
  • Unfortunately, many versions in the Djvu virus family are not decryptable because of the use of online IDs. This is the case for Kasp virus too, so even the decryption tools like Emsisoft Djvu decrypter is not helpful. 
  • You can try to recover some of the media files with this data restoring tool.
  • Then, the best option – data backups. This is the method that could help you restore affected files using copies of the encrypted data. It is very important – DO NOT ADD BACKUP DEVICE TO YOUR PC WHEN THE VIRUS IS STILL PRESENT. You may risk getting your files permanently damaged this way.
Elimination You should think about Kasp ransomware removal immediately when the ransom demands appear on the screen. To get rid of the ransomware – get a proper anti-malware tool and run the thorough system scan that allows the program to find all the malicious files and associated programs
System repair solution Besides the proper virus removal procedures, you should also make sure that traces of the ransomware and virus damage is not affecting the performance of your machine in the future. That can be ensured with tools like Reimage Reimage Cleaner Intego that check for damaged, affected files and can repair various functions, system files for you

Kasp ransomware is the virus that gets distributed via malicious files and holds the particular data for ransom, so criminals gain cryptocurrency from the victims. The message that creators deliver straight to your desktop and other folders states that paying is the best solution and that you have no other options for file restoring.

However, the _readme.txt file provides contact information and steps needed to take, so you can get your files recovered, but criminals are dangerous, and based on the past versions, there is no need to contact virus creators since Kasp ransomware infection may lead to other malware attacks. Criminals can send you malicious files instead of the proper decryption tool, so ignore the message and all the claims.

Kasp file virus creators deliver the text file with a message:

ATTENTION!

As any other cryptovirus, this threat demands money and tries to scare victims into providing payments. Those claims about decryption tools are not trustworthy, especially when this threat is not new and based on powerful methods and widely spread ransomware creators. You should rely on anti-malware tools and remove Kasp ransomware as soon as you got the ransom note on the system, so the threat is properly detected and terminated.[3]

Kasp ransomware virusKasp ransomware - cryptovirus that creates ransom-demanding message in a text file with the encouragement to pay up.

Kasp ransomware should be terminated so that you can rely on options available for the system repair and file recovery. Typically, the malware attempts to contact its Command & Control server to retrieve a unique key that can only be useful for one victim. However, if this process fails, .kasp extension files might be able to be recovered with the help of the Djvu decryption tool in the future. Thus, it is extremely important that you would keep affected data on a separate medium until somebody pays the ransom and shares an offline ID with security researchers from Emsisoft.

Since there is no way to know when such events would occur precisely, you can keep running the updated version of the decryption tool. If .kasp files are encrypted with an online ID (which means that the virus successfully contacted its Command & Control server), you will see a similar message:

Error: No key for New Variant online ID: zGFdql6hM5fwiUxSnWic63XlOuDCeoRUhF47vKUA
Notice: this ID appears to be an online ID, decryption is impossible

This notification means that the decryption tool will not work for your particular case, and it will be impossible to retrieve encrypted files using the Djvu decryption tool. Keep in mind that Kasp ransomware removal with security software will not remove .kasp extension from the affected data, as anti-malware solutions are not designed for that. 

To get rid of the Kasp files virus, you should employ powerful anti-malware programs, such as SpyHunter 5Combo Cleaner or Malwarebytes. While Djvu variants are known to eliminate themselves after the initial encryption is performed, it is important to note that security experts previously spotted malware being spread with other infections, such as AZORult.[4]

Besides, the malware might also inject malicious components into Google Chrome, Mozilla Firefox, or another web browser in order to steal sensitive information about you, e.g., login data or banking details. Data theft is very common when Kasp ransomware infection occurs, as malware authors can sell harvested information on the underground forums for profits.

Kasp files recovery optionsKasp files might be retrievable with Emsisoft's decryption tool for Djvu in the future

Before you scan the machine with security software, however, you should copy all the affected files to a separate storage device, such as USB flash. This will ensure that the data will not get corrupted in the process; and note that encrypted .kasp files are not dangerous, as they do not hold any malicious code inside them.

Once that is done, you can attempt to restore all the files encrypted by this infection using alternative methods, which you can find below. Keep in mind that these solutions have low success rates due to the sophistication of the Kasp ransomware virus:

  • Windows recovery solutions such as System Restore or Windows Previous Versions feature. Unfortunately, automated recovery backups are usually deleted by the virus during the infection routine;
  • Third-party recovery applications. These tools might sometimes be able to retrieve some of the working copies from your hard drive.

Remember that if you add new files on the system before removing Kasp virus completely, you risk getting your files encrypted again. The procedure of terminating the virus can be difficult since there are many changes made in the system folders that affect various functions – these system features can usually be repaired with tools such as Reimage Reimage Cleaner Intego.

Malicious files – method of distribution that ransomware employs 

The worst thing about all the cyber infections is the spreading method that involves malicious campaigns and services that people often use. This threat can spread quickly because one infected software crack file gets downloaded thousands of times, and this is the only interaction required for the malware to be triggered.

Once the user downloads malicious email attachments from the email notification or gets the pirated software file installed, it allows that malicious script to launch the payload of the ransomware directly on the system. Then ransomware can starts the encryption in the background. There are some reports that Flash Update and Adobe packages can spread this particular version.

Pay attention to sources and files you download, so you can avoid such infections. Also, keeping anti-malware tools on the system could help since these malicious files might be detected and quarantined by your AV tool before the infection even happens.

Get rid of the .Kasp files virus

It is known that Kasp ransomware virus and other threats from the cryptovirus category can act harmless and spread quickly. The coding is powerful, and there are fewer things that can stop the encryption from running quickly. As soon as you get the ransom-demanding message, the threat is pretty much done with its job of affecting your files, so the removal should start ASAP.

Kasp files virus

You should go for Kasp ransomware removal and get SpyHunter 5Combo Cleaner or Malwarebytes for the job since such anti-malware programs can find these dangerous threats and delete them alongside other associated files and applications.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Kasp and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, 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.
