请叫我MayBe：了解在线社交网络上共享手机号码的性质和风险
Call Me MayBe: Understanding Nature and Risks of Sharing Mobile Numbers on Online Social Networks
摘要：
人们对OSN上个人信息泄露的可能性非常关注，但很少有定量研究。本研究探讨了通过公开配置文件和帖子在OSN上共享手机号码的活动。我们试图了解OSN上手机号码共享行为的特点和风险，并专注于印度手机号码。我们收集了85905名用户在Twitter和Facebook上发布的76,347个独特的手机号码，并分析了2997个前缀为+91的号码。我们观察到，大多数用户共享自己的手机号码是为了传播紧急信息;推销产品和护送业务。在OSN上分享手机号码的女性用户更少。用户利用其他OSN平台和第三方应用程序（如Twitterfeed）在多个OSN上发布手机号码。与用户对数字在OSN上快速传播的看法相反，我们观察到，除了紧急情况外，大多数数字并没有深入传播。为了评估与OSN上暴露的手机号码相关的风险，我们使用号码通过整理来自OSN、Truecaller、OCEAN的公开数据来获取有关其所有者的敏感信息（例如姓名、选民ID）。在WhatApp上使用这些号码时，我们获得了号码所有者的大量敏感信息（关系状态，BBM引脚）。我们通过电话向业主传达了观察到的风险。很少有用户对他们的号码在网上的存在感到惊讶，而其他一些人则出于商业目的故意在网上发布。我们观察到，38.3%的用户不知道他们的号码在网上的存在，他们自己在社交网络上发布了他们的号码。根据这些观察结果，我们强调有必要监控通过个人资料和公开帖子泄漏的移动电话号码。据我们所知，这是第一次探索性研究，以批判性地调查印度手机号码在OSN上的曝光情况。
英文摘要：
There is a great concern about the potential for people to leak private information on OSNs, but few quantitative studies on this. This research explores the activity of sharing mobile numbers on OSNs, via public profiles and posts. We attempt to understand the characteristics and risks of mobile numbers sharing behaviour on OSNs and focus on Indian mobile numbers. We collected 76,347 unique mobile numbers posted by 85905 users on Twitter and Facebook and analysed 2997 numbers, prefixed with +91. We observed, most users shared their own mobile numbers to spread urgent information; and to market products and escort business. Fewer female users shared mobile numbers on OSNs. Users utilized other OSN platforms and third party applications like Twitterfeed, to post mobile numbers on multiple OSNs. In contrast to the user's perception of numbers spreading quickly on OSN, we observed that except for emergency, most numbers did not diffuse deep. To assess risks associated with mobile numbers exposed on OSNs, we used numbers to gain sensitive information about their owners (e.g. name, Voter ID) by collating publicly available data from OSNs, Truecaller, OCEAN. On using the numbers on WhatApp, we obtained a myriad of sensitive details (relationship status, BBM pins) of the number owner. We communicated the observed risks to the owners by calling. Few users were surprised to know about the online presence of their number, while a few others intentionally posted it online for business purposes. We observed, 38.3% of users who were unaware of the online presence of their number have posted their number themselves on the social network. With these observations, we highlight that there is a need to monitor leakage of mobile numbers via profile and public posts. To the best of our knowledge, this is the first exploratory study to critically investigate the exposure of Indian mobile numbers on OSNs.
