How to Decrypt .zida 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?"

Most of the times this means you have an online ID. It could likewise imply your data were encrypted by a more recent variation of STOP/Djvu.

Offline ID's normally finish in t1 and are typically very easy to recognize. Since the offline key and ID only alter with each variant/extension, everyone that has actually had their documents encrypted by the very same variation will have the same ID as well as the data will be decryptable by the same key (or "private key when it comes to RSA encryption).
  • Online ID. In most cases the ransomware has the ability to attach to its command and control servers when it secures documents, and also when this takes place the servers react by creating arbitrary keys for each infected computer system. Because each computer system has its own key, you can not utilize a key from an additional computer to decrypt your documents. The decrypter can functioning around this with older variants as long as it has some assistance, nonetheless for more recent variations there is absolutely nothing that can be done to recoup documents.
