This paper aims to raise awareness of a rapidly emerging privacy threat that the authors term cybercasing: leveraging geo-tagged information available online to mount real-world attacks. While users typically realize that sharing locations has some implications for their privacy, they provide evidence that many are unaware of the full scope of the threat they face when doing so, and often do not even realize when they publish such information. The threat is elevated by recent developments that make systematic search for geo-located data and inference from multiple sources easier than ever before. In this paper, they summarize the state of geo-tagging; estimate the amount of geo-information available on several major sites, including YouTube, Twitter, and Craigslist; and examine its programmatic accessibility through public APIs.
