DHS chief refutes cyberattack claim behind US FAA nationwide ground stop

The chief of the U.S. Department of Homeland Security publicly denied that a cyberattack triggered the nationwide ground stop ordered by the Federal Aviation Administration. The statement came after speculation linked the abrupt halt of flights across the country to a possible security breach. The DHS official emphasized that investigations have found no evidence of malicious hacking affecting the FAA’s operational systems. The denial aims to reassure airlines, passengers, and the public that the disruption was not the result of a cyber threat. Authorities continue to monitor the situation and work to restore normal flight operations.
