DALLAS - The City of Dallas is investing $4 million in a system aimed at preventing future cyberattacks.
The City Council's plan for a detection system comes two months after Dallas was hit by a ransomware attack.
The attack in early May, carried out by the group known as Royal, took down city systems, including police and fire dispatch, courts, online payment systems, the Dallas Public Library and Dallas Animal Services among others.
