Snapchat flaw exposes 4.6 million users
Security flaws in the Snapchat APIs let hackers collect the long list of names, which was then posted on the Internet for all to see on January 1. Gibson Sec warned Snapchat of the threat several months ago, but apparently it hasn't been patched.
The Gibson Sec team says they didn't steal the database, but they have put together a website that can check to see if you're one of the unlucky 4.6 million. To see if you're on the list, just enter your Snapchat user name at Gibson Sec's Snapchat leak site.
The culled accounts all come from specific parts of North America, so users outside the U.S. are most likely not on the list. If you are, it's time to delete your Snapchat account. That won't remove your name from the list that's already been released, but it will stop anyone else from getting your information if they try a copycat move.
Even though passwords weren't collected in the breach, it's still a good reminder to make sure you aren't using the same login credentials for every site or service you use. Apps like 1Password and LastPass can store your passwords for you so it's easier to keep track of your logins.
