Hi all,

 

This morning i realize there was a readme.hta on my desktop and did a system search on it and deleted them all (1000+ entries). I did not get any specific ransom note messages and malwarebytes didn't throw any issue with the system or with the 'readdme.hta' files either. Note that I DID NOT run readme.hta eevn once yet and my wallpaper did not change to the randsom note either

 

However, i realised most of my important files now have encrypted names with file extension .963E( e.g. -1dlTZmAtJ.963E) . Using ID Ransomware (beta') as shared by the website turns up CERBER 3.0  

 

Not sure what happened/ how did it happen?  How I can decrypt the files now? what else can I do to ensure deletion was thorough? (i did not find any .exe so the executable is still not identified)

 

Sadly, I did not do any system restore/bakcup/shadow volume as per suggested earlier. What are my options for decrypting?

Any files that are encrypted with the newest Cerber variant will be renamed (encrypted) with 10 random characters and have a random 4 character extension appended to the end of the encrypted data filename (i.e. 1xQHJgozZM.b71c) and leave files (ransom notes) named README.hta...see here.

Trend Micro released a Ransomware File Decryptor for victims of earlier Cerber infections but it has limitations...must be used on the infected machine, may take several hours to complete decryption, some files may be only partially decrypted. However, victims have reported the decryption tool does not work on Cerber v3/v4 encrypted files.

There is an ongoing discussion 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.

Thanks
