Several million Snapchat usernames and phone numbers were apparently leaked online late Tuesday night.
The New Year may have only just started, but for Snapchat developers it has already been marked by the greatest security fail in the mobile app’s history.
The anonymous group of hackers has compiled and dumped a database containing phone number information of 4.6 million Snapchat users, along with their usernames, to a webpage simply labeled SnapchatDB.info.
“You are downloading 4.6 million users’ phone number information, along with their usernames. People tend to use the same username around the web so you can use this information to find phone number information associated with Facebook and Twitter accounts, or simply to figure out the phone numbers of people you wish to get in touch with,” the site said.
Although the last two digits of the leaked phone numbers have “for now” been censored out “in order to minimize spam and abuse,” the group says one should feel free to contact them and ask for the uncensored version of the database, which they agree to release “under certain circumstances.”
In its blog post of Dec. 27, Snapchat described how its Find Friends feature allows users to upload their contact lists to Snapchat as a way of linking up friends.
According to that post:
“Adding a phone number to your Snapchat account is optional, but it’s helpful for allowing your friends to find you. We don’t display the phone numbers to other users and we don’t support the ability to look up phone numbers based on someone’s username.”
On Jan. 1, Snapchat CEO Evan Spiegel told that the company is “working with law enforcement,” and will “update when we can.”
