Ransomware is where hackers gain access to a computer system and then prevent its legitimate users from accessing the data until they pay a ransom. Hospitals have often been targeted. The city government of Atlanta is the latest victim of this practice, having been locked out of its computers since last Thursday.
I presume all these institutions do backups of their systems pretty much all the time. So why, when attacked like this, can they not do a complete wipe of their systems and then reload using the backup? It may take some time, of course, but that can’t be why they don’t do it since the Atlanta lockout has gone on for almost a week.
I know that there are computer experts who read this blog. Can anyone explain this?
