How to Decrypt .qstx 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 might also indicate your files were secured by a more recent version of STOP/Djvu.

  • Offline ID. When the ransomware can not link to its command and also control web servers while encrypting your documents, it utilizes a built-in encryption key and also an integrated ID. Offline ID's normally end in t1 as well as are usually easy to identify. Since the offline key and also ID just alter with each variant/extension, everyone who has actually had their data secured by the same variant will have the very same ID and the documents will certainly be decryptable by the very same key (or "private key when it comes to RSA security).
  • Online ID. Most of the times the ransomware is able to attach to its command as well as control servers when it encrypts data, and also when this happens the web servers respond by producing arbitrary keys for each contaminated computer. Since each computer system has its very own key, you can't use a key from another computer to decrypt your files. The decrypter can working around this with older variations as long as it has some assistance, 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!
