TAIPEI, Taiwan -- Taiwan participated in a multinational cyber exercise held by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) for the first time earlier this year, according to the island's Administration for Cyber Security.
The 11 participating countries included Australia, Canada, Finland, Japan, the Netherlands, New Zealand, Norway, Singapore, Sweden, Taiwan, and the United Kingdom, according to the CISA report.
After the exercise, the Taiwanese and U.S. participants shared information, with both parties describing it as a success and saying that lessons learned could be added to their domestic response mechanisms, according to the cyber administration.
Any cooperation with the United States on cybersecurity is key for Taiwan, considering the island is one of the main targets for China's cyberattacks.
Hardware vendors, the government and military sector, and manufacturing were the three hardest-hit sectors during the period, the outlet said.
Recorded Future said that RedJulliett was mostly likely based in Fuzhou, a city in southern China's Fujian Province.
"Given the close geographical proximity between Fuzhou and Taiwan, Chinese intelligence services operating in Fuzhou are likely tasked with intelligence collection against Taiwanese targets," Recorded Future said. "RedJuliett is likely targeting Taiwan to collect intelligence and support Beijing's policy-making on cross-strait relations."
The Chinese Communist Party considers Taiwan a part of its territory and has carried out influence operations in an attempt to influence the island's public opinion and election outcomes.
Chinese state-sponsored threats, such as Salt Typhoon, have also targeted the United States.
