Tick, also known by aliases such as Bronze Butler and REDBALDKNIGHT, is a long-standing cyber espionage advanced persistent threat (APT) group believed to be operating out of China, with some reports linking it to the People's Liberation Army (PLA) Unit 61419. The group emerged as early as 2006 and has consistently focused on persistent access for intelligence gathering rather than large-scale, disruptive attacks. Their primary motivation is cyberespionage, aimed at acquiring sensitive political, diplomatic, military, and industrial information, as well as intellectual property and product details to benefit Chinese strategic interests and gain industrial advantage. What sets Tick apart is its disciplined approach to sustained, covert operations, its methodical improvement of malware over time, and its propensity to exploit region-specific software vulnerabilities, especially within Japanese and South Korean enterprises. The group operates under multiple names, including BRONZE BUTLER,
