Cybersecurity group FireEye said Thursday it found evidence that hackers linked to the Chinese regime exploited a flaw in a Microsoft email application to go after a number of American targets, including a university and local governments.
FireEye analysts wrote in a blog post that the company built “higher-fidelity detections” and launched multiple threat hunting campaigns after Microsoft confirmed earlier this week that a Chinese state-sponsored hacking group known as “Hafnium” had exploited vulnerabilities in Microsoft’s Exchange Server email program.
