It's not something with which I have personal experience, but it seems to me you need to make a special effort to signal to the world that you've reformed and are an ethical and trustworthy person. Perhaps start a blog and update it regularly, sharing your expertise and industry insights about security, along with your personal story about how you came to engage in criminal behaviour, what you've learned through the experience, and what you've done to rehabilitate yourself. You might also want to re-think the kinds of companies you're applying to. If it's large, established, mainstream companies, they are likely to be risk-averse, and perhaps beholden to company policies to not hire people with convictions. But earlier-stage companies, that still have a strong hacker/rebel culture and where the hiring decisions are still made by the founders, may be more welcoming.
