The Chrome extension – called Marauder’s Map (apropos of the same Harry Potter magical artifact that gave users the ability to see exactly where people were) – exposed the major Facebook privacy flaw in Messenger. Within three days of launching the extension (and after publicizing it through Twitter, Reddit, and a Medium post), it was downloaded by more than 85,000 people until Khanna was asked by Facebook to disable the app. Facebook then deactivated location sharing from desktops shortly after and released a Messenger app update that gave users full control on when and how to share their GPS data. But prior to that, the company had been sharing automatic geolocation sharing since 2011; it wasn’t until after Khanna’s app exposed the Facebook privacy misgiving that Facebook did anything to address it. Facebook spokesman Matt Steinfeld told Boston.com: And Facebook, it seems, did whatever it can to keep Khanna quiet about the whole situation. A day after he posted Marauder’s Map, his would-be manager at Facebook asked him not to talk to press, which was followed by a similar message from Facebook’s global communications lead for privacy and public policy. On the day that the app was deactivated – and a mere two hours before he was to leave to start his internship – Khanna was told by a Facebook employee that his internship offer was being rescinded for violating Facebook’s user agreement. It’s all pretty shady business, even for a company whose responsibility with online user data and privacy haven’t exactly been extolled. While this news is certainly shocking, it’s likely not a surprise to many. In a report released earlier this year by the Pew Research Center, 69 percent of adults in the United States have very little to no confidence that social media sites like Facebook will keep their personal data private and secure. And, indeed, this recent case adds further support to that belief. Khanna managed to land himself a summer position at a Silicon Valley startup and has since published a case study in the Harvard Journal of Technology Science documenting the response from the company after exposing the critical Facebook privacy flaw.
