A hacker hijacked public crosswalk announcements in April to broadcast impersonations of Mark Zuckerberg and Elon Musk, revealing how unprepared local authorities are for infrastructure attacks.

The incident, documented in records obtained by WIRED, demonstrated a straightforward vulnerability in connected city systems that officials failed to anticipate or secure. The hacker accessed crosswalk audio systems—infrastructure designed to assist pedestrians—and used them to broadcast celebrity impersonations. The attack was unsophisticated but effective, exposing the lack of basic security protocols protecting public infrastructure. Local authorities had no prepared response and struggled to contain the breach once discovered. The incident highlights a critical gap: cities are deploying connected systems faster than they implement safeguards. As municipalities increasingly adopt smart infrastructure for traffic management and public safety, security remains an afterthought. The crosswalk hack serves as a warning that even low-tech attack vectors can compromise public systems when basic access controls are absent. Experts emphasize that protecting connected infrastructure requires baseline security measures—authentication, monitoring, and regular audits—currently missing from many municipal deployments.
