How to Decrypt .btnw 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?"

For the most part this means you have an on-line ID. It might additionally imply your data were secured by a more recent version of STOP/Djvu.

  • Offline ID. When the ransomware can not connect to its command as well as control web servers while encrypting your data, it utilizes an integrated security key and a built-in ID. Offline ID's generally finish in t1 and are usually very easy to determine. Considering that the offline key and ID only transform with each variant/extension, everyone that has actually had their data secured by the exact same version will have the very same ID and the files will be decryptable by the same key (or "exclusive key in the case of RSA encryption).
  • Online ID. In most cases the ransomware is able to attach to its command as well as control servers when it encrypts files, as well as when this occurs the servers respond by generating random keys for each and every contaminated computer. Given that each computer system has its very own key, you can't utilize a key from another computer to decrypt your data. The decrypter is capable of functioning around this with older variants as long as it has some aid, nevertheless for more recent versions there is absolutely nothing that can be done to recover 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!
