That is after security researcher Markus Neis surfaced private data belonging to a number of Fortune 500 companies via Google, Bing and other search engines. Box.com said it's a classic case of users accidentally oversharing. Neis isn't convinced and says Box.com's so-called Collaboration links shouldn't have been indexed in the first place. Box.com has since blocked access to what security researchers say was a treasure trove of confidential data and fodder for phishing scams.
