How to Decrypt .kool files?

Djvu Ransomware essentially has two versions.

  1. Old Version: Most older extensions (from “.djvu” up to “.carote”) decryption for most of these versions was previously supported by STOPDecrypter tool in case if infected files with an offline key. That same support has been incorporated into the new Emsisoft Decryptor for these old Djvu variants. The decrypter will only decode your files without submitting file pairs if you have an OFFLINE KEY.
  2. New Version: The newest extensions released around the end of August 2019 after the ransomware was changed. This includes .coharos, .shariz, .gero, .hese, .xoza, .seto, peta, .moka, .meds, .kvag, .domm, .karl, .nesa, .boot and etc….These new versions were supported only with Emsisoft Decryptor.

"The decrypter can't decrypt my files?"

In many cases this indicates you have an on-line ID. It could also imply your files were encrypted by a more recent version of STOP/Djvu.

  • Offline ID. When the ransomware can not connect to its command and control web servers while securing your documents, it uses a built-in security key and also a built-in ID. Offline ID's typically end in t1 and are normally very easy to determine. Because the offline key as well as ID just change with each variant/extension, every person that has had their data secured by the very same version will have the very same ID as well as the files will certainly be decryptable by the same key (or "private key in the case of RSA file encryption).
  • Online ID. In many cases the ransomware is able to link to its command and also control web servers when it encrypts files, and when this occurs the web servers respond by producing arbitrary keys for each and every contaminated computer. Considering that each computer has its very own key, you can't make use of a key from an additional computer system to decrypt your documents. The decrypter can functioning about this with older versions as long as it has some aid, however for more recent variations there is nothing that can be done to recuperate data.

In case when the tutorial doesn’t help, download the anti-malware tool we suggest or try free online virus checker. Furthermore, you may always ask us in the comments for assistance!
