It looks like one of my Windows servers was infected with Ransomware. Has anyone had any experiences with removing ransomware? Also, my main concern is my dropbox folder. Is it possible for the files in that folder to become infected and spread it to other machines that I have DB installed on?

First of all, holy shit.

Second, can you tell us which Ransomware affected your machine?

It usually comes from downloading something.

Also, yes, it can probably affect your dropbox. Here's more info on that:

https://www.dropbox.com/en/help/8406

Finally, I think you may be able to get rid of it by using the restore option (taking your computer back to before the virus was infected) or finding a program that will get rid of it for you.

I'm not an expert though. I think either @davids355 or @bartosimpsonio can help you better than I can. These things are tricky and they're always evolving.
 
used to work in an IT shop about a year ago, and for ransomware we refused to try and save the files, told the customer that he has two options: pay the ransom and hope you actually get your stuff back (unlikely ) or we can wipe the whole system. its a bitch.
 
What do you mean infected?

Have you performed a full scan, or did the antivirus detected the ransomware based on his actions?

Did any program show asking you to pay money?

You can also send the detected file to totalvirus to check...

It can also be a false positive...

A full scan with malware anti malware bytes should help you as well...
 
Why did you refuse? Was it a lot of work or just impossible to get rid of?

whole pc was locked down, you could log on and open files but they came up with gibberish, pc would lock down with a message demanding payment when trying anything to restore the pc.
looks normal at first glance on desktop but any word on the pc was turned into gibberish.

it was the customers business pc aswell and he lost all info on there basically his work was crippled because of it, and to no surprise he didn't have copies of important work related documents. since then i made it a point to basically pressure everyone into at least making one complete and separate backup of important crap.

it was impossible (for us) to get rid off it and we didn't know any other place that could attempt to unlocked it. we refused to save the customer money and time.
 
Wow.

Well it makes sense to save time and money.

@tymillz Can you afford to wipe your PC? Do you have backups of your files?

Ransomware encrypts your files/file sytem. It is impossible to recover it without decryption key which attacker promise to give when you pay. Because usually you have time limit, and nobody (i mean regular people, breaking ETA could be 10 years) has computing power to break encryption in time.
 
@alwaysinvisible thats what I am going to have to do. Its a virtual server so its no big issue. My main concern was my dropbox account. I wasnt sure if there was a way for them to infect those files and then infect all of my other servers.

Here is the message that was left when I logged into the server...


All your important files were encrypted on this computer.
You can verify this by click on see files an try open them.

Encrtyption was produced using unique public key RSA-4096 generated for this computer.

To decrypted files, you need to otbtain private key.
The single copy of the private key, with will allow you to decrypt the files, is locate on a secret server on the internet;
The server will destroy the key within 48 hours after encryption completed.

To retrieve the private key, you need to pay 7 bitcoins

Bitcoins have to be sent to this address: 1HrEqMHQVWhKuCg7a3rxo2tAFAiKquJ5iP

After you've sent the payment send us an email to : [email protected] with subject : DECRYPT-ID-63100177
If you are not familiar with bitcoin you can buy it from here :
SITE 1 : www.coinbase.com
SITE 2 : www.bitstamp.net

After we confirm the payment , we send the private key so you can decrypt your system.

Just as some have mentioned here hopefully you keep solid backups. I've found it to be nothing short of a pain in the ass when trying to clean a server with something that is meant to spread adding to the cost of both your time and money. Good luck. Hopefully you have a baseline clone of your server and or a BDC that you can switch to.

Personally I'd never go anywhere near this. Ransomware is literally the shittest thing one can do, but boy are they making some serious green.

@tymillz If you are concerned about the Dropbox files I wouldn't worry too much, as I doubt the virus would be that advanced, but to be in the safeside you could always download the files and put them onto a VM or fresh VPS and see what they do. Also, try change the pw for dropbox and log out from everywhere for a while

Wait, if I were you I would unplug the lan of all the computers that have dropbox (before starting that machine) just to be on the safe side.
 
You can only get rid of it via re installing the os ....

Next time make a backup of everythink you got including the os.

ransome softwere lock's password even dll files and can only be open with the key code...

It inpossable to break all the codes from the os

Sorry it new os

Remeber this ransom also go to other harddrives connected to your computer ...

You can try to restore computer from a restart point ,but i am sure wont work...

This is usally from free programs you have downloaded, or a website you really shouldnt of Visited.
 
I think there is no way to recover files without paying for key. Its easy to remove virus by using antivirus but main issue is infected files.Try deep web may be you will find solution with less $$
 
Working on something now. Ill let you guys know how it turns out. Worse case scenario Ill just wipe the server. The good thing is that its one of my Virtual's and not any of my actual hardrives.
