Don't dream... It's not so simple. Recently the Ransomware gang asked $42m from a NewYork law firm, threatened to leak dirt on Trump as well.
Screenshots published on the site hinted that hackers stole documents pertaining to their customers, Lady Gaga, Madonna and many more.
So if the Ransoware guys could be caught there are several law enforcement guys working on it in many countries. No need for us to worry.
