The latest Facebook "10 Concerts" craze is putting smiles on the faces of hackers looking to access your personal information.
The popular meme asks users to list 10 concerts they've attended, but leaves it up to followers to determine which one is a lie.
However, USA Today reports security experts are worried about giving away too much, especially when users continue by answering the question of which was the first concert they ever saw.
"First concert" is a question many people answer for security clearance to their online personal information.
“If I’m a hacker, I’m taking full advantage of this,” says Fatemeh Khatibloo, an analyst with Forrester Research, told USA Today.
Experts say when divulging personal information on Facebook, people should set posts to private and to never make those answers public.
