Evolution of Chinese-Nexus Cyber Operations: Strategic Long-Term Threats Recent research from Darktrace reveals the evolution of Chinese-nexus cyber operations over the past two decades, highlighting a shift from high-volume attacks to more strategic, identity-centric intrusions. This change reflects a broader integration of cyber operations into long-term geopolitical strategies, with a focus on critical national infrastructure and supply chains. The analysis, titled Crimson Echo, covers anomalous activities observed from July 2022 to September 2025, identifying two primary operational models: 'smash and grab' and 'low and slow.' The 'smash and grab' model involves rapid data exfiltration within 48 hours, while the 'low and slow' model emphasizes stealth and persistence. This long-term approach allows attackers to maintain access and evaluate strategic value over time, posing significant risks to targeted organizations. The findings underscore the need for enhanced cybersecurity measures to address these evolving threats. 255 sources 73
