Snapchat is largely dismissing claims that its built-in friend-finding feature could be used by hackers to discover users' phone numbers. A security group detailed the potential exploit in August, explaining that by uploading enough phone numbers through Snapchat's address-book-lookup tool, a hacker could eventually find the phone number that belonged to a person whose username they knew within the app. Gibson Security says the exploit could check 10,000 numbers in 7 minutes Though it was allegedly alerted to the potential issue, Snapchat didn't respond until today — two days after the discovering research group, Gibson Security, published details of the app's private API, exposing how the exploit could be accomplished.
