CSO Online: FireEye breach explained: How worried should you be?

Cybersecurity firm FireEye announced Tuesday that a sophisticated group of hackers, likely state-sponsored, broke into its network and stole tools the company’s experts developed to simulate real attackers and test the security of its customers. While this is a worrying development, it’s unlikely that this will result in a significant risk increase to organizations, as some offensive tool leaks did in the past.
