You’ve seen the headlines of how businesses were harmed by ransomware. Ransomware depends on encryption; there is a public key and a private key. Unless you have the private key, you can’t readily get your data back. Any time you hear someone say that they went to a site such as nomoreransom.org and got their data back, it was because some organization was able to obtain the private key and post it there. You can’t always depend on that situation.
