I am not familiar with snap chat as I seldom chat any longer. However a site called SnapchatDB.info has released 4.6 million count with usernames and phone numbers available for download. According to the website they got the information to a recently identified snap chat exploit. They say that they released this information in an effort to convince snapchat to beef up their security. If you are one very users I suggest that you be very careful of any information that is passed through that application. SnapChat said they have limited resources available but security and privacy should be job one. With this application and any other watch what you have available as it may bite you in the end.
