A public policy expert mapped global cybercrime laws to develop a five-point framework for protecting ethical hackers and good-faith security research.

The crime solver wore disguises, spied on targets, and built intelligence networks long before modern-day tactics emerged. He has lessons for today's ethical- and unethical hackers.

A study of more than 6,000 patches found that even working patches can introduce new bugs, break something else, or are open to bypass.

The fight against cybercrime continues because threat actors have adapted their strategies to avoid deterrents, but law enforcement still operates in silos.
