How to Decrypt .mztu 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 means you have an online ID. It could additionally suggest your files were encrypted by a more recent version of STOP/Djvu.

  • Offline ID. When the ransomware can not attach to its command as well as control servers while securing your data, it utilizes a built-in file encryption key and also an integrated ID. Offline ID's usually end in t1 and are usually very easy to recognize. Since the offline key and ID only change with each variant/extension, everyone that has had their documents encrypted by the same variant will have the same ID as well as the documents will be decryptable by the very same key (or "private key when it comes to RSA file encryption).
  • Online ID. Most of the times the ransomware is able to connect to its command as well as control web servers when it encrypts documents, as well as when this takes place the servers react by creating random keys for every infected computer. Because each computer has its very own key, you can't make use of a key from an additional computer to decrypt your data. The decrypter can functioning about this with older variants as long as it has some aid, however for newer versions there is absolutely nothing that can be done to recuperate data.
