Hi everybody,

 

yesterday we have a virus attack in Ukraine. Our server has Microsoft Essential antivirus which has caught Petya.A virus. It seems that we survived the attack but I found that mostly all DOC, XLS and PDF files are broken. I have checked disks with different antivirus and have found nothing. Those files are on the shared drive. I suppose that they were broken from outside.

The question is could you help me to recover those files?

 

Thank you!

 

Sergey

1. Download Malwarebytes Chameleon at https://downloads.malwarebytes.com/file/chameleon and run it like described in the help file in the archive you will download. Don't be scared about your taskbar and such disappearing. This is intended.

2. Download Malwarebytes Anti Rootkit at https://downloads.malwarebytes.com/file/mbar and run it. DO NOT DELETE ANYTHING IT FINDS. ASK US FIRST. IT OFTEN FINDS STUFF THAT IS NEEDED BY WINDOWS OR OTHER SOFTWARE.

NotPetya Is a Cyber-Weapon. It's Not Ransomware

The NotPetya ransomware that encrypted and locked thousands of computers across the globe yesterday and today is, in reality, a disk wiper meant to sabotage and destroy computers, and not ransomware. This is the conclusion of two separate reports coming from Comae Technologies and Kaspersky Lab experts. Experts say that NotPetya also known as Petya, Petna, ExPetr operates like a ransomware, but clues hidden in its source code reveal that users will never be able to recover their files.


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
