At least in the US their seem to be nearly everyday reports of various size cities and governments having their computer systems held hostage for large sums of money. The FBI gets involved. Who is solving this problem and what is are the names of the companies in this space?
No one really can solve crypto malware. That’s what makes it so scary. The problem is that the attackers are locking up data with mathematically secure cryptography that, outside of something like a bad key or an insecure phone home, can’t really be beat with anything short of a fully working version of shors algorithm. The vast majority of solutions appearing for these are for poorly made ones. That have glaring holes in their implementation, weak command and control, or terrible attack surface management. The only hope people have is the author of the locker was a piss poor developer and left behind holes that can be exploited. Short of that the only solution is basically maintain regular full backups on tape that are sent to air gapped cold storage nightly. If you don’t have that, seems the only choice left is to pay.
Regular backups help. At most you lose a day's worth of data. And of course the hassle of doing restores.
