On Friday, the U.S. announced sanctions on China’s Integrity Technology Group, a cybersecurity firm linked to the Chinese hacking group Flax Typhoon, which has been accused of carrying out a litany of cyberattacks on Americans in recent weeks. China’s escalating cyberespionage campaign against the U.S. and its allies is one of the more overlooked stories, yet its stakes are intensifying. As cyber-attacks ramp up, top China cybersecurity expert Samm Sacks argues that the U.S. must decide whether to take a hardline approach in regulating critical industries vulnerable to attack. “Our system is so vulnerable,” says Sacks, we could find ourselves “essentially rebuilding it from scratch.”
