How to Decrypt .btos 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 on-line ID. It can additionally mean your data were encrypted by a newer variation of STOP/Djvu.

  • Offline ID. When the ransomware can not link to its command as well as control servers while encrypting your files, it makes use of a built-in encryption key and also an integrated ID. Offline ID's normally finish in t1 and also are typically simple to determine. Given that the offline key and also ID just transform with each variant/extension, every person who has actually had their data encrypted by the same variation will certainly have the same ID and also the files will be decryptable by the same key (or "exclusive key in the case of RSA file encryption).
  • Online ID. In many cases the ransomware has the ability to attach to its command and control web servers when it encrypts data, and when this happens the web servers react by producing arbitrary keys for each infected computer. Considering that each computer has its very own key, you can't utilize a key from another computer system to decrypt your data. The decrypter is capable of functioning around this with older variations as long as it has some aid, however for more recent versions there is absolutely 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!
