Andray, Then it's mostly an online ID and decryption is not possible. I suggest that you backup all encrypted files, and store them safely. If in the future law enforcement or security researchers are able to gain control of the cyber-criminals command & control server and are able to retrieve the encryption keys.

Hello Andray, Thank you for contacting Emsisoft Support. This is a newer variant of STOP/Djvu. If you have an offline ID, then once we can find the decryption key for this variant and add it to our database you will be able to recover your files. However, if you have an online ID (which is more likely) then it will not be possible to recover your files. There is more information at the following link: https://support.emsisoft.com/topic/32045-about-the-stopdjvu-decrypter/

Hello Ruman, Thank you for contacting Emsisoft Support. Let's make sure of what we're dealing with. Please visit the following website and upload both an encrypted file (between 256KB and 2MB in size would be best) and a ransom note simultaneously for proper identification, and send me the information it provides: https://www.emsisoft.com/ransomware-decryption-tools/ Please be sure to read the information link on the results page, as whether we have a decrypter or not, sometimes someone else's decrypter is listed, or other information is available that might be useful for recovery. You might try undelete software such as Recuva from Piriform, or if your files are very important, it may be worth talking to a company that specializes in negotiating with the criminals that created the ransomware, such as Coveware, at https://www.coveware.com/. They are one of the few companies that do this completely transparently and honestly. If the identification process shows a ransomware that is not decryptable, there is nothing else we can do. We do not recommend paying the ransom unless there is absolutely no other choice.

@mminee Yes, this is GarrantyDecrypt. Unfortunately, GarrantyDecrypt cannot be decrypted without paying the ransom. Also, I see you posted a support request on Bleeping Computer. You should not post asking for assistance on more than one forum. Even though we have a close working relationship with Bleeping Computer we do not actively monitor their forums, nor do they monitor ours. By posting on multiple forums, the techs that see your posts may not be aware that you are receiving assistance on another support forum.

Unfortunately, this is a newer variant of mosk that changed the way the produce encryption keys. Therefore we are not able to decrypt your files. I suggest that you back up all the encrypted files, in case we or another security are able to crack this version and issue a working decrypter for this variant.

Please upload an encrypted file and its original unencrypted version to https://decrypter.emsisoft.com/submit/stopdjvu/ A word of caution, if the files were recently encrypted, then this may not work for you.

We have identified "STOP (Djvu)". This ransomware may be decryptable under certain circumstances. Please refer to the appropriate guide for more information. Identified by: sample_extension: .mosk sample_bytes: [0x1C8F - 0x1CA9] 0x7B33364136393842392D443637432D344530372D424538322D3045433542313442344446357D ransomnote_email: [email protected] Click here for more information about STOP (Djvu). Case number: 858a6fa5cdd735b9f4c9001d42381624841d2fe01575916172

In the case of larger scale ransomware attacks, restoring from backups is not economically feasible. Which is why many companies, enterprises, and governmental agencies often choose to pay the ransom. From the financial perspective it is much cheaper, and operational it gets the data back much quicker.

@spikey what @JeremyNicoll is getting at as long as outlook.pst is open by another application, i.e. Outlook and Acronis. Exclusions in Emsisoft may not take effect until outlook.pst is no longer open by another application or the next reboot. Also keep in mind that you must clear all previous detection's against outlook,pst as they take precedence over any whitelist rule for outlook.pst.
