I had to share this story, and i believe if your dealing with this situation then READ this!
We were attacked by this virus a week ago, the hacker left us an @india.com email to reach out in order to get the keys.
we sent email, and he was quick to reply with his demand ".....send me only 4 bitcoins , and i'll provide you with the program which will unlock your files...".
we were happy, only $3k (in bitcoins) and this will all "go away"
So we sent the 4 bit coins (i was so stupid to fall for this,) as soon as i submitted payment, I emailed asking for the key, the hacker then replied, "......thank you for the 1ST payment, now please send us 75 bit coins"...." i course refused, then he replied with a link to an Online Counter Clock (see picture i took http://imgur.com/a/KVs3Y) and he gave us 24 hours to pay , and from this point the nightmare started :-(
The Hacker stated he has copies of every file, database and email on the network, as proof he sent us copies of files and screenshots entire mailboxes, and if will not meet his demands he will delete or post the files and email online (what ever he feels like)
We are in the medical business, and something like that will destroy us, we are now a victim of extortion, and there is no way out of this, not the FBI, local police or anybody can help now.
All i can say is DON'T PAY, don't communicate and you will be safe! i read posts here and people say, "..pay this hacker he is trustworthy, dont pay this one he is not..."), People!!! they are all criminals and they are all NOT to be trusted, the criminal will leverage this situation as much as he can, learn from my experience and you will be safe :-( , the biggest mistake i did was to email and communicate, try find other ways to resolve it.
don't make the same mistake i did.
