This research paper applies the extended diamond model in an attempt to illustrate Chinese cognitive warfare waged against Taiwan during the 2020 election. The paper is informed by 320,000 pieces of data, collected between May 1, 2019 and January 31, 2020, that demonstrate abnormalities on the Internet and the attribution of these abnormalities to possible players in China. According to the data collected, four different attack models existed during the 2020 election: the propaganda model, the pink model, the content farm model, and the collaboration model. This paper suggests that we need different defensive mechanisms to counterattack information operations from China.
