(NEW YORK) -- Snapchat has responded to its recent data breach, which left the usernames and phone numbers of about 4.6 million users exposed, saying it plans to upgrade security.
In a blog post Thursday, the photo-sharing website said it will be releasing an "updated version of the Snapchat application that will allow Snapchatters to opt out of appearing in Find Friends after they have verified their phone number."
The "Find Friends" feature "asks Snapchatters to enter their phone number so that their friends can find their username." The optional service appears to have been at the center of the New Year's Eve breach.
Snapchat also said it is "improving rate limiting and other restrictions to address future attempts to abuse our service."
