`Microsoft accuses China over email cyber-attacks'

`Microsoft has blamed a Chinese cyber-espionage group for attacks on its mail server software. The tech giant said the hackers belonged to a state-backed group, which was a "highly skilled and sophisticated actor". In a blog post, Microsoft said the hacking campaign made use of four previously undetected vulnerabilities in different versions of the software. The security flaws allowed the hackers to remotely access email inboxes. Microsoft's Threat Intelligence Centre attributed the attacks with "high confidence" to Hafnium, a group assessed to be state-sponsored and operating out of China. It based its conclusion on "observed victimology, tactics and procedures". Microsoft said Hafnium targets infectious disease researchers, law firms, higher education institutions and defence contractors. Policy think tanks and non-governmental groups have also been targeted. This is the eighth time in the past 12 months that Microsoft has publicly accused nation-state groups targeting institutions critical to civil society. Although Hafnium is based in China, it conducts its operations primarily from leased virtual private servers in the US, Microsoft said..'.
[Note: Not to be confused with the element hafnium, atomic number 72, which is named after the Latin name for Copenhagen. I wonder if the Chinese group chose the name because the element hafnium proved very difficult to isolate and identify and it was confused with zirconium for a long time.]
