Hsieh is hardly alone. A newly released analysis by security researcher Cesar Cerrudo and reported by ITWorld.com found that executives like Hsieh, including many at Fortune 500 firms, frequently use their business e-mail addresses to access a wide range of prominent social media web sites. Cerrudo, the Chief Technology Officer of security firm IOActive Labs, scanned 30 prominent Web sites, uncovering 840 unique e-mail addresses of C-level corporate executives linked to 930 online accounts. They include 42 Facebook accounts linked to e-mail accounts for executives of firms such as oil giant Chevron, blue chip firm GE and financial services firms Chase.com and Morgan Stanley. Robert Iger, the CEO of Disney, uses his corporate e-mail to log in and watch movies on Netflix. Denise Morrison of Campbell’s Soup used hers to connect with friends on Facebook and make travel plans with United Airlines. Despite their deep rivalry, Steve Ballmer of Microsoft and Tim Cook of Apple both have accounts at the cloud-based file sharing service Dropbox.com linked to their corporate e-mail address, Cerrudo’s data suggests."
