A series of tweets have unveiled a significant development in cybersecurity, revealing an unprecedented leak of documents from a Chinese hacker known as #iSoon or #Anxun in Chinese. These documents, which appeared on GitHub, expose in extraordinary detail the scope of China’s state-sponsored cyberattacks on foreign governments, including plans to target UK government data. The leaks show the global reach of China-sponsored hacking, with the Foreign Office and Amnesty International among 20 departments and think tanks listed as potential targets for cyber espionage. The leaked files link back to an organization with ties to China’s Ministry of State Security and the People’s Liberation Army, including pictures of custom hardware snooping devices. This revelation has sparked concerns about the efforts of the Chinese government to target critical infrastructure with cyberattacks.
