Karsten Hahn on Twitter: "New #YYTO #ransomware variant, but with albertkerr94@mail.com.m5m5 extension

Unfortunately, there is no known way to decrypt files encrypted by YYTO without paying the ransom. If possible, your best option is to restore from backups or wait for a possible solution at a later time. If you can find the malicious executable that you suspect was involved in causing the infection, it can be submitted here. Doing that will be helpful with analyzing and investigating by our crypto malware experts.

There is an ongoing discussion in this topic where victims can post comments, 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.

Thanks
