How to Decrypt .maas 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 on-line ID. It might likewise mean your files were secured by a more recent variant of STOP/Djvu.

  • Offline ID. When the ransomware can't attach to its command and control web servers while securing your files, it uses a built-in encryption key as well as an integrated ID. Offline ID's typically end in t1 and are usually simple to determine. Because the offline key and ID only transform with each variant/extension, everyone that has actually had their files encrypted by the very same variant will have the exact same ID as well as the files will be decryptable by the very same key (or "exclusive key in the case of RSA security).
  • Online ID. In most cases the ransomware has the ability to attach to its command as well as control web servers when it secures data, as well as when this occurs the web servers react by creating random keys for each contaminated computer. Given that each computer system has its own key, you can not use a key from another computer to decrypt your data. The decrypter can working about this with older versions as long as it has some help, 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!
