How to Decrypt .isak 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 might additionally imply your data were encrypted by a newer version of STOP/Djvu.

  • Offline ID. When the ransomware can't connect to its command and also control servers while encrypting your files, it makes use of a built-in file encryption key and an integrated ID. Offline ID's generally end in t1 as well as are normally simple to determine. Given that the offline key and also ID only alter with each variant/extension, everybody that has had their data secured by the very same variation will have the very same ID and also the data will be decryptable by the same key (or "exclusive key when it comes to RSA file encryption).
  • Online ID. In most cases the ransomware is able to attach to its command as well as control web servers when it secures files, as well as when this happens the web servers react by creating arbitrary keys for each contaminated computer. Considering that each computer has its very own key, you can't utilize a key from an additional computer system to decrypt your documents. The decrypter can working around this with older variations as long as it has some help, however for more recent variants there is absolutely nothing that can be done to recuperate files.

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!
