You're going on holiday and would like your Facebook friends to know. So you post a photo of your boarding pass –what's the worst that could happen, right?
In an experiment, Steve Hu from iflyflat.com.au reveals how ridiculously easy it would be for fraudsters to have access to your personal information including frequent flyer logins, and even credit card details. Yes, just from posting a photo of your boarding pass.
We've compiled a list of seven other pieces of information you should never post online.
1. Your ID
Full names, birth date, place of birth. This is just some of the information that identity thieves crave. And they can get it on your ID or drivers' licence. Guard this information at all cost.

2. Your credit card details This may seem fairly obvious but...
3. Your password
Another obvious one, but it's always worth mentioning. Along with your actual password, avoid sharing information that could help crack security questions, for example, the name of your first pet, or your favourite colour.
4. Your phone number
As technology advances, so do scammers' tech skills. Not only does this leave you exposed to phishing scams, but they could also send you malicious text messages.
5. Your address
By sharing your address on Facebook, you're putting yourself at risk. For instance, if you've shared that you're going on holiday, people know you've got an empty house. Even if you have a small circle of Facebook friends you trust, if your account is not secure, internet-savvy burglars could easily find your house at the click of a button.
6. Your schedule
Similarly, sharing your daily routine leaves you open to danger.
7. Your running route
So you've taken up jogging – great. But akin to sharing your address, posting your regular jogging route places you in a vulnerable situation.
