New ransomware called NOLS that encrypts documents with .nols extension

Hi, I work in an a law firm and yesterday I realized that we had been attacked by a ransomware that encrypted very critical documents and changed them to .nols extension hence rendering them inaccessible. I was able to remove the virus manually, now I want to know if there is any possible way I can decrypt the files. It is a critical matter so kindly assist with any possible solutions.
