Oops. Yale University recently announced that the names and Social Security numbers of 43,000 people affiliated with the school were publicly available online for about 10 months. Ivy League institutions, they're just like us: completely and utterly exposed.

Yale Daily News reports that the information was stored on an open source FTP, a type of server that Google began indexing in September 2010. "It was pretty well-hidden, with a very inconspicuous file name," Yale's IT director explains, which means it would have been compromised only if somebody had been "dorking."

"Dorking" is "just doing Google searches in a special way that reveals sensitive info," according to resident hack expert and confirmed dork Adrian Chen. Apparently dorking breaches happen pretty often: In the last month, the private data of 7100 Purdue students and 1800 North Carolina school children were similarly exposed.
