How to Decrypt .oonn 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 can likewise indicate your data were secured by a newer variant of STOP/Djvu.

  • Offline ID. When the ransomware can not attach to its command and also control servers while encrypting your files, it makes use of an integrated security key and also an integrated ID. Offline ID's usually finish in t1 and are typically simple to recognize. Because the offline key and also ID only alter with each variant/extension, every person who has had their documents secured by the very same variant will certainly have the exact same ID as well as the documents will be decryptable by the same key (or "private key in the case of RSA file encryption).
  • Online ID. In many cases the ransomware has the ability to connect to its command and also control web servers when it encrypts documents, as well as when this happens the servers respond by producing random keys for each and every contaminated computer system. Given that each computer system has its very own key, you can not utilize a key from an additional computer system to decrypt your data. The decrypter is capable of working around this with older versions as long as it has some aid, nonetheless for more recent versions there is nothing that can be done to recuperate documents.

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!
