Silicon Valley crosswalk buttons hacked to imitate Musk, Zuckerberg’s voices

Audio-enabled pedestrian crosswalk buttons in multiple Silicon Valley cities were hacked over a weekend to play AI-generated speech impersonating Mark Zuckerberg and Elon Musk; videos circulated online and local officials are investigating. The report highlights that such devices often use default credentials and have been previously shown to be physically or remotely manipulated, suggesting low-to-moderate technical exploitation likely motivated by hacktivism rather than large-scale destructive intent.
