CAC declares Micron products pose “serious network security risks” in cybersecurity review

China's Cyberspace Administration (CAC) has declared that products from US chipmaker Micron have failed a cybersecurity review, saying they posed “serious network security risks” and threatened “critical information infrastructure supply chain” and national security.[0] No specific risks were identified, but the ban could affect Micron's 11% of revenue derived from sales to non-Chinese firms for products manufactured in China. Micron said it was evaluating the review and assessing its next steps, but former FBI counterintelligence official in Beijing Holden Triplett said the decision was “retaliation for the US’s export controls on semiconductors”.[1]
