What do I do for income

Programming, math...

Areas of expertise: everything I've written about in my books.

Despite the fact I've written RE4B, and found several CVEs, I'm not in infosec, and almost never been (except for a brief experience), so it's senseless to offer me a job in that area.

I don't take full-time job offers, and almost never did. If you want to hire me for a project, please write me an email about it, stating clearly your situation, your goal, etc. How much time you have for it and max budget.
