Operation Shady Rat: China's Cyber Espionage Engine

The source provides an overview of Operation Shady Rat, a long-running, extensive campaign of cyber-espionage attributed to a unit of the Chinese military (Unit 61398) starting around 2006. This operation involved Advanced Persistent Threats (APTs) utilizing simple but effective spear-phishing emails to install malware (often referred to as a "rat") on victims' systems globally. The primary goal was intellectual property theft and technology transfer, leading to significant economic growth for China, exemplified by the alleged theft of F-35 fighter jet plans from Lockheed Martin. Although initially brazen and unconcerned with attribution, Chinese cyber operations later became more careful following public exposure and international pressure, shifting their focus toward maintaining covert access to critical infrastructure in other nations.
