This emphasis on Russia should not blind us from the more dangerous Cyberattacks coming from CHINA!
The Chinese People’s Liberation Army has several divisions ( hiring tens of thousands of hackers ) dedicated to cyber warfare.
This has been documented by Bill Gertz in his book: “Deceiving the Sky: Inside Communist China’s Drive for Global Supremacy”
The Russians also have plenty of government-sponsored hackers, and really, I suspect the Russian ones are more talented as a rule. China, as always, favors quantity over quality, even when it comes to skill-based endeavors.
