It is believed these "@"
infections are part of a ransomware kit that different affiliates utilize with their own payment email addresses and explains why so many variants have been reported. They all have similar messages (ransom notes) and country of origin varies.
You can submit samples of encrypted files and ransom notes to ID Ransomware
for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.
There is an going discussions in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
