The FBI has reported a cyber attack on the Virgin Islands offices of the Virgin Virgin Islands, which was first detected in February, to Congress as a "major incident" that could threaten national security. The breach was reported in compliance with the Federal Information Security Modernization Act of 2014, which requires notification of specific committees in both Houses of Congress if a federal agency's computer system is compromised. The hackers reportedly accessed sensitive data stored directly on FBI systems, marking a major counterintelligence coup for China. The news comes as President Donald Trump prepares for a trip to China.
