It's fake. As a social media platform, Tik Tok mainly provides users with the function of sharing short videos, and there is no official information about the examination or recruitment process directly related to network security officers. I received a call claiming to be from Tik Tok, claiming to be a network security officer, suggesting to be vigilant. In order to earn training fees, Tik Tok called and said that it was false to take the exam as a network security officer.
