An anonymous reader shares a Motherboard report: Every year, Forbes' 30 Under 30 list recognizes people blessed with both youth and exceptional talent in their field -- including celebrities, startup founders, doctors, and artists. These are smart, savvy professionals -- and when some of them include information security pros, they're bound to go poking around for vulnerabilities. That's what Yan Zhu, a privacy engineer who made the 2015 list, was doing when she found a gaping privacy hole in the way Forbes handles recipients' personal information. Once you make the list, Yan told me in a Twitter direct message, Forbes asks you to register for its annual Under 30 Summit conference. "They send you a link for conference registration, but it's not tied to your email address," she said. "So you can literally enter anyone's email address who is also a 30 Under 30 member and it shows you their personal info." That information carries over into all future years, she said.
