One of the oldest churches in San Francisco is suing Zoom Video Communications Inc. after a hacker infiltrated its virtual bible study and subjected participants to pornography.

The lawsuit, brought by Bottini & Bottini and Cotchett, Pitre & McCarthy on behalf of Saint Paulus Lutheran Church, is part of a growing number of legal actions against Zoom, which has gained more than 2.2 million new active users this year. The company’s privacy and security practices have come under heightened scrutiny as the platform has emerged as a crucial tool for remote communication during the COVID-19 pandemic.
