Security researchers found several vulnerabilities within TikTok s infrastructure that made it possible for potential attackers to hijack accounts to manipulate users’ videos and steal their personal information. TikTok is a social media platform owned by Beijing-based ByteDance, with offices around the world, servers based in the countries where its iOS and Android apps operate, and it is used for sharing short-form looping mobile videos of 3 to 60 seconds. U.S. military branches including the Army, Navy, and Air Force have banned the Chinese-owned TikTok app from soldiers’ government-issued smartphones.
