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]<p>I couldn't find my own data in the set, and actually it seems like lots of entire area codes are missing.<p>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.<p>It appears there are two Canadian area codes represented in the database: 867 and 204. There are also 248 US area codes which are <i>not</i> 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 <i>not</i> 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.<p>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
