A leading celebrity lawyer has advised his clients not to use smartphones and the iCloud after intimate photos of Oscar-winning actress Jennifer Lawrence and female entertainers and models were posted online following an apparent mass hacking. Martin Garbus, a New York trial lawyer who over the years has represented actors Al Pacino, Sean Connery, Robert Redford and others, said on Tuesday worried clients have approached him about security issues. Everything on your iPhone, whether it be phone calls, message texts, pictures, is all available. Garbus said clients started to contact him after intimate photos of Lawrence, a star of The Hunger Games movie franchise and a best actress Academy Award winner for Silver Linings Playbook, and other high-profile women began appearing on Sunday. Personal photos of Sports Illustrated swimsuit model Kate Upton and American actress Mary Elizabeth Winstead were also posted on the image-sharing forum 4chan.
