Late at night, in the central control room of Jiangcheng Petrochemical Plant No. 3, Engineer Cui Hanming on duty was staring at the beating data stream. A tiny traffic anomaly lasting only 0.4 Seconds—a "glitch" that could have been ignored—triggered his professional vigilance. Following the data traces in reverse, he discovered a strange MAC address that flashed like a ghost, trying to access the internal wireless network from the edge of the factory. Immediately afterwards, a precise scam call came in pretending to be from the Emergency Management Bureau, asking for monitoring permissions.
Technical probing and social engineering attacks highly overlap in time. Faced with this carefully planned targeted attack, this silent night watchman stood alone in the nerve center of the industrial behemoth, building the last line of defense with professionalism and calmness. As the data flows calmly, a silent secret war has begun.
