Encountered - Engaged - Damaged
I had an encounter this week with Grandcrab 5.1 and unfortunately not even Bitdefender is able to decode it. They can do it with versions up to 5.0, but not 5.1.

How did I engage? I tried to help a friend, inserted my usb stick, turned on the internet as it was needed for my action and Gradcrab 5.1 activated.

I didn't realize it until I noticed that some files from my usb stick changed names. 

I was also amazed by the led of usb stick running wild after turning internet on. I knew something was wrong. That was the crypting doing its job.

In 3 minutes the entire folders with txt, docs and zip files were damaged / encrypted.

Luckly I had backups and so my friend, but one thing is obvious: Windows Defender defended NOTHING.

Other systems from same place with Bitdefender installed with Antiransomware and preboot options active were protected.

This is not advertising to this AV provider, it's just a happy case with one damaged computer from 7.

We saved some encrypted files for future use and see if any decryptor will help, but it will be at least 6 months until one will be public.

Thank you
