In March 2020, cybersecurity firm FireEye reported that Chinese state affiliated hacker unit APT41 had waged a cyber campaign affecting 75 organizations in over 20 countries. The intrusions affected government agencies, non-profits, media organizations, and companies in sectors including finance, high tech, and energy. Using a vulnerability in software distributed by companies including Cisco and Citrix, APT41 launched a remarkably broad cyber action. FireEye described the attacks as “one of the broadest campaigns by a Chinese cyber espionage actor (…) in recent years.”
