By Michael LiedtkeThe Associated PressSAN RAMON, Calif. — Back in March as the coronavirus pandemic gathered steam in the U.S., a largely unheralded video-conferencing service suddenly found itself in the spotlight. And just as quickly as Zoom became a household name for connecting work colleagues, church and school groups, friends, family, book clubs and others during stay-at-home lockdowns, it also gained a reputation for lax security as intrusive “videobombers” barged into private meetings or just spied on intimate conversations. On April 1, following a wave of lawsuits over privacy breaches, CEO Eric Yuan ordered a halt to work on new features and vowed to fix the service’s weaknesses in 90 days.
