Last week, Gibson Security – a group of “white hat” hackers, meaning they don’t exploit the security gaps they find – published what they said was code that would enable such a hack. Snapchat did not immediately respond to a message seeking comment.

In the statement, the hackers said they blurred the last two digits of the phone numbers they posted but were still considering whether to post more with the full number visible.īy Wednesday afternoon, developers had used the data to set up a website letting Snapchat users find out whether their accounts had been compromised.
