Turns out a lot of people who write Ransomware, are not very good at it. No More Ransom!
Nevertheless, it is sometimes possible to help infected users to regain access to their encrypted files or locked systems, without having to pay. We have created a repository of keys and applications that can decrypt data locked by different types of Ransomware.
The list of Decryption tools available is quite long. (Especially when you consider that when done correctly, you can’t decrypt ransomware without help from the folks who wrote it.)
Update: There is also a list of Things-to-Do in advance, so you have less chance of being hit with ransomware.
