Microsoft Threatens Legal Action Over Exploit Disclosure

Microsoft’s response to a researcher publicly disclosing proof-of-concept exploit code has reignited an old debate in security: where does responsible disclosure end and reckless disclosure begin? Tom and Scott discuss the Nightmare Eclipse controversy, the history of full disclosure, bug bounty incentives, and why legal threats against researchers may ultimately hurt customers. They also explain why researchers still need to follow responsible processes — and why vendors need to avoid punishing the people who help make their products safer.
