GT500 812 Report post Posted January 16, 2019 Just so that everyone knows, Michael Gillespie is still working on analyzing the encryption method of the ransomware. There appears to be some conditions under which it might be decryptable, and if he can find a way to help with recovery of files then he will more than likely let me know (or BleepingComputer will announce it in their news).

GT500 812 Report post Posted April 3, 2019 @ren normally I would recommend uploading a copy of the ransom note and an encrypted file to ID Ransomware in order to verify which ransomware you're dealing with, however I would believe that the "djvur" extension was only used by one of the Djvu variants of the STOP ransomware. Go ahead and following the instructions in this post to download and run STOPDecrypter to see if it can decrypt your files. If it can't find a key for you, then it will tell you your ID and MAC, which you can paste in a reply and I can forward to Michael Gillespie (the creator of STOPDecrypter) so that he can archive your information in case he is able to figure out your decryption key at some point in the future. 1 Quote Share this post Link to post Share on other sites

We would need the MAC addresses of the network devices on the infected computer as well. There's a batch file that can get them for you. Just download and open the ZIP archive at the following link:https://www.gt500.org/emsisoft/MAC_Address_Batch_File.zip After opening it, a folder will appear with a file named Get_MAC_Addresses. Just double-click on that file, and a black window will appear and disappear. Once that black window disappears, you will have a new file on your Desktop called MAC_Addresses. Just attach that "MAC_Addresses" file to a reply. BTW: If you were using some sort of mobile WiFi/mobile broadband connection when your files were encrypted, then make sure it is at least connected to the computer when you run the "Get_MAC_Addresses" batch file.

GT500 812 Report post Posted April 30, 2019 5 minutes ago, ren said: Here it is MAC: 30:9C:23:0D:68:F7 Thanks Only one MAC address? If you have more than one network adapter, and that's the wrong MAC address, then it more than likely won't be possible to figure out your decryption key. Admittedly it's late enough that the odds of being able to figure out the decryption key are low to begin with, however there's still a small chance as long as we have the correct MAC address.

GT500 812 Report post Posted May 2, 2019 MAC addresses of network adapters don't change after reformatting, so that MAC address is the same as the one you sent before. Did you run the batch file? You keep attaching the batch file to your replies, and not the "MAC_Addresses" file it saves on your Desktop. Quote Share this post Link to post Share on other sites

When you upload a file pair, the decrypter can only decrypt other files that have the same first 5 bytes as the file you used for your file pair. Normally this means all files of the same type (such as all MP4 files or all ZIP archives), however there are some exceptions to this where not all files of the same type will begin with the same 5 bytes (JPEG/JPG images and TXT files are good examples).
