This is a huge gift for those who were infected with ZeroLocker as it was previously thought that their files were irretrievably lost. Now an affected user can follow the instructions on Visula's site and potentially decrypt their files and regain full access to them again. In order to use the decryption tool a user will need to have Microsoft Net Framework v4.0 installed and should run the tool on the fastest computer they own. The more CPUs a computer has the faster the tool will be able to brute force the decryption key.
If the data is time sensitive, then you can use a service like Amazon Web Services and rent c3.8xlarge Windows server. This will allow you to throw 32 virtual cores at the brute force task and significantly speed up the process. The only caveat to this is that it costs $1.68/hour to rent these servers.
As always if you have any questions regarding this process, please feel free to ask us and we will help as much as we can. A big thanks to Vinsula for releasing this free tool and reaching out to us to so that we can let our visitors know about it.
