30,000 U.S. organizations breached by cyber espionage group Hafnium
At least 30,000 organizations in the U.S. have been hacked by a Chinese cyber espionage unit, known as "Hafnium." The group is targeting and exploiting security vulnerabilities in Microsoft Exchange Server email software.
Last week, Microsoft released emergency security updates to fix the vulnerabilities and announced the group operates from China with the purpose of exfiltrating information from a number of industry sectors, including infectious disease researchers, law firms, higher education institutions, defense contractors, policy think tanks and NGOs.
