Menlo Park

The surprise message were noticed over the weekend in Palo Alto, Redwood City and Menlo Park - which is home to Zuckerberg's sprawling Meta campus.

In Menlo Park, the home of Zuckerberg’s Meta, another viral video showed his spoofed voice greeting pedestrians.

In Menlo Park, the locally controlled crosswalk signals that include audio recordings were not hacked and city officials are working with the crosswalk signal manufacturer to ensure they are not hacked in the future, city officials say.

A series of viral videos posted on social media showed crosswalk speakers playing derisive messages about billionaire tech giants Elon Musk and Mark Zuckerberg in Palo Alto, Menlo Park and Redwood City as perplexed onlookers laughed.

However, the Caltrans operated crosswalk signals in Menlo Park were hacked on El Camino Real and near the Meta campus.
