I've heard that quantum computers may soon be powerful enough to crack standard encryption. If this is true, could we potentially harness them to end ransomware? Instead of paying the ransom or coming up with some alternate solution, could someone who was hit with ransomware just pay a company to break their computer's encryption?
... quantum computers may soon be powerful enough to crack standard encryption.
I don't know what "soon" means for you, but surely not in the next few years.
And, quantum computers might be in some time be powerful enough to crack what is considered today "standard encryption", but encryption moves on too. For one, one can for some time just increase the length of keys, but there are also already algorithms for post quantum cryptography which are hopefully resistant against quantum computers.
I mean hopefully, since what ransomware uses to take away data from their rightful owners are basically the same algorithms which are used to protect data from unauthorized access. So any major advantages in cracking ransomware in general also means loss of rightful data protection.
