Microsoft is threatening legal action for disclosing exploits

Microsoft is facing criticism for its handling of zero-day exploits. Someone going by the name Nightmare Eclipse has been publicly feuding with the company, posting proof-of-concept exploit code. Some of their posts suggest that they're a disgruntled former employee.

But what caught cyber security researcher Kevin Beaumont's eye was how Microsoft has responded. Microsoft suggests it plans to bring a criminal case against Nightmare Eclipse for failing to follow "proper coordination" in disclosing vulnerabilities.
