"Evil" Exposes Facebook Users' Phone Numbers

Have you ever created a Facebook group called, “I lost my phone and need your phone numbers!”, or something similar? If so, you may have just made all of you and your friends’ phone numbers public. Leveraging the new Graph API, Tom Scott developed an interesting tool which crawls public Facebook groups for the phrase “lost phone” and then collects the phone numbers of all the users.

As Tom Scott pointed out to Mashable, this isn’t exactly something that you couldn’t do using Google, it’s just that automatic the process appears to be much more “Evil”, hence the name of the tool (which can be found here).
