How to Decrypt .iiss 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 online ID. It can also suggest your documents were encrypted by a more recent variation of STOP/Djvu.

  • Offline ID. When the ransomware can't attach to its command as well as control web servers while encrypting your data, it utilizes an integrated encryption key as well as a built-in ID. Offline ID's normally end in t1 and also are normally easy to determine. Because the offline key and also ID just transform with each variant/extension, everybody who has actually had their data encrypted by the same version will have the exact same ID and the files will certainly be decryptable by the very same key (or "personal key when it comes to RSA security).
  • Online ID. Most of the times the ransomware has the ability to connect to its command as well as control web servers when it secures documents, and also when this occurs the servers react by generating random keys for each infected computer. Since each computer system has its own key, you can't utilize a key from an additional computer system to decrypt your data. The decrypter can functioning about this with older variants as long as it has some aid, nevertheless for more recent variations there is absolutely nothing that can be done to recoup 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!
