While not perfect, this is a nice little tool to have in the toolbox just in case. I haven’t tried it personally, but it is said to decrypt files infected from the list below. Keep in mind there are some issues with certain strains, such as CryptXXX V3 and CERBER, so be sure to read the instructions and notes before proceeding. Hopefully you will never need this, but if you do, good luck.
