Kasp Ransomware Removal [Explained]

What is Kasp Ransomware

Kasp Ransomware is malware than encrypts files. It comes from the notorious Djvu/STOP ransomware family, which has released hundreds of ransomware that are more or less identical. You will be able to tell which ransomware is inhabiting your computer by the extension added to encrypted files. This ransomware adds the .kasp extension, hence why it’s known as Kasp ransomware. It’s a dangerous piece of malware because it encrypts files, and there currently is no way to recover files for free without backup.

This ransomware will drop _readme.txt ransom note, which is practically identical to the notes dropped by other Djvu versions. Cyber criminals explain in the note that they can decrypt your files, provided you pay $980 in ransom. According to the note, if victims contact them within 72 hours, the ransom would be lowered to $490. However, paying the ransom, or even contacting these cyber crooks for that matter, is not recommended. You have no way of being sure that you would actually receive the decryptor if you pay, and we doubt they will feel any kind of obligation to help you. And even if you do get sent a decryptor, it won’t necessarily work.

It is, unfortunately, currently impossible to decrypt files for free. Older versions of Djvu are decryptable, and there is a free decryptor available but it will not work for Kasp or other new versions. Backup is the only free way to recover files. However, if you do have backup, you should be very careful to fully remove Kasp Ransomware before accessing it because if the ransomware is still present, it may encrypt files in backup as well.

Is there a Kasp Ransomware decryptor available for free?

The ransomware was initiated when you opened the malicious file. It immediately started encrypting files, photos, videos and documents in particular. All affected files are marked with the .kasp file extension. For example, document.doc would become document.doc.kasp. You will be unable to open these files, unless you decrypt them. To decrypt them, you’d need to purchase the decryption software from the cyber crooks behind this ransomware.

When the encryption process is complete, the ransomware will drop the _readme.txt ransom note. The note is pretty typical, it reassures that files can be decrypted if you pay the ransom. The ransom sum is $980 but if users make contact within 72 hours, it would be lowered to $490. helpmanager@mail.ch and restoremanager@airmail.cc are given as the contact addresses.

However, because cyber crooks cannot be trusted, paying the ransom is not recommended. It’s not uncommon for victims to not receive anything after paying the ransom, and this may happen in your case as well. Furthermore, while users continue to pay the ransom, ransomware remains a profitable business for cyber crooks.

Ransomware is one of the reasons why regularly backing up files is very important. If you had backed up files prior to your computer getting infected, you could easily recover files once the ransomware is no longer present.

It is possible that a free Kasp ransomware decryptor will be released in the future, but one is not available as of now. And because there are many fake decryptors out there, you should be very careful. Only trust legitimate sources to provide safe decryptors. You have the option of backing up encrypted files and waiting for a free decryptor to become available.

How did Kasp ransomware infect your computer?

It’s more than likely that your computer got infected with Kasp ransomware when you opened a malicious email attachment and enabled macros. Cyber criminals purchase leaked email addresses from dark web forums and use them to launch spam email campaigns. Your email address was likely leaked somewhere, which is why you received the malicious email. You can usually recognize malicious emails by paying attention to certain things. First of all, spam emails are often sent from random email addresses. They’re also full of grammar and spelling mistakes. As long as you are attentive when opening emails, you should be able to recognize spam/malicious ones. Just as a precaution, you should scan all unsolicited email attachments with anti-virus software or VirusTotal.

Other means of catching the infection include pirating content (movies, TV series, games, software, etc.) via torrents, and clicking on ads when on high-risk websites.

Download the program from an official web page and install it. Scan your computer once the installation process is finished. If any files come up, you may recover them.

  • Shadow Explorer. Shadow Explorer will be able to retrieve copies of the files but only if ransomware did not delete them.

Use the official web page to get Shadow Explorer and install it. When you open the program, choose the disk from which to restore the copies. Right-click and press Export on any folders that appear. Unfortunately, the majority of ransomware does delete shadow copies so as to pressures users to make the ransom payment.

Getting in the habit of backing up files on a regular basis would help avoid these types of situations in the future. Protecting your device with anti-malware that has ransomware protection features would also help. The anti-virus would stop the ransomware in its tracks and prevent file encryption.
