Own it, and capitalize on it! You've already written the first sentence of your sales pitch: "I was involved in a high-profile computer hacking case in 2015 which received international interest."

Continue with "therefore I know about system security...". Write a book, charge a huge rate as a consultant. I'm serious. If you act like a beaten-down person, you'll be treated as one.

It's classic making lemonade from lemons, but it can really work. If not, you've lost nothing.
