How to Decrypt .booa 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 most cases this indicates you have an online ID. It could also suggest your files were encrypted by a newer variant of STOP/Djvu.

  • Offline ID. When the ransomware can't connect to its command and control web servers while securing your files, it utilizes an integrated encryption key and also a built-in ID. Offline ID's generally end in t1 and also are generally simple to identify. Given that the offline key and ID only change with each variant/extension, every person that has had their data secured by the very same variation will have the very same ID and also the data will be decryptable by the very same key (or "exclusive key when it comes to RSA security).
  • Online ID. Most of the times the ransomware has the ability to link to its command and control servers when it secures data, and when this takes place the web servers respond by producing random keys for each and every contaminated computer system. Because each computer system has its own key, you can't utilize a key from one more computer system to decrypt your files. The decrypter can working around this with older variants as long as it has some assistance, however for newer variations there is nothing that can be done to recuperate data.

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!
