Are there any obvious file extensions appended to or with your encrypted data files? If so, what is the extension and is it the same for each encrypted file or is it different? Some types of ransomware will completely rename, encrypt or even scramble file names while others do not append any extensions.

Did you find any ransom notes and if so, what is it's actual name? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Most ransomware will drop a ransom note in every directory/affected folder where data has been encrypted. These notes are often created in multiple file formats (.txt, .html, .png) to ensure that the victim can open them. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a .html, .txt, .png, .bmp, .url file.

is that the case SHA1 from ID Ransomware? If so, please be patient until Demonslay335 can manually inspect it.

I agree, it is Unlock92 2.0. No extension was added to the files uploaded by the victim. Here's the ransom note image they uploaded though, called "qtekaadhxdli.jpg".

 

Also, the Tor address was already on ID Ransomware since May 2017, it would have been identified if you typed it into the Addresses box. I've added the email address for future detections. I'm unsure if the image name is random or not, no other uploads with that name.

Since the infection has been identified, rather than have everyone with individual topics, it would be best (and more manageable for staff) if victims posted any more questions, comments or requests for assistance in the below support topic discussion.To avoid unnecessary confusion, this topic is closed.

Thanks
