Someone pulled a fire alarm during the February 2018 school shooting in Parkland, Florida, which killed 17 students and teachers. The alarm caused more students to move into the hallways and into harm’s way. “Hackers no longer use cyberattacks to cause cyber damage,” says an expert. Instead, “they are using these attacks to cause physical damage or put people in locations to maximize physical damage.” Sports venues, with tens of thousands of spectators, are especially vulnerable. To combat the cyber threat in sports, scientists built an assessment tool for team and stadium owners to fix vulnerabilities.
