Snapchat Phone Number Database Leaked
The top comment on Reddit r/netsec's corresponding coverage has mirrors on Mega.co.nz for the files [1]I couldn't find my own data in the set, and actually it seems like lots of entire area codes are missing.Assuming `cat schat.csv | uniq | cut -c1-4 | wc -l` is the proper command, there are only 76 of 322 [2] US area codes represented.It appears there are two Canadian area codes represented in the database: 867 and 204. There are also 248 US area codes which are not represented in the database. Assuming a relatively uniform distribution of phone numbers in the US (which is not at all a safe assumption), the average US snapchat user has better odds of not being in the list than being in it. Sampling from the set of my snapchat friends who are not in my area code, 3 of 13 can be found in the database.If your phone number is in any of these states, you're not in the database: Alaska
Delaware
Hawaii
Kansas
Maryland
Mississippi
Missouri
Montana
Nebraska
Nevada
New Hampshire
New Mexico
North Carolina
North Dakota
Oklahoma
Oregon
Rhode Island
Utah
Vermont
West Virginia
Wyoming[1] http://www.reddit.com/r/netsec/comments/1u4xss/snapchat_phon...[2] I'm matching a regex against this list http://en.wikipedia.org/wiki/List_of_North_American_Numberin...
