You'll have more chance if you manage to block the ransomware, rather than trying to clean up the mess after. It would also be a lot better as not every ransomware is decryptable, nor is it possible to always revert the damage.
Do you already have programming experience?
Some yes, in Python2, Some Ruby, Some Rails, and very little HTML+CSS.
I'm not to interested in C/C++ but if i have to i could learn it.
And i know one size does not fit all but i was thinking of ADDING key or something similar (e.g. RC5 with a SHA1 Check sum or something like that. (
and yes of course it is better to be protected before you browse the internet but some still don't understand that even adds and run scripts and start a silent background install/ execute.
Like a SOMEWHAT universal Decrypter.
Obviously one person can not do all of that, so id like to put all the heads we can get possible together and brainstorm.
I understand not all malware is decryptable as the different variations as you had mentioned.
I'd just like to make it Easier for everyone. haha.
