You may at some point get excited about something and post it on social for all your friends and family and maybe even the rest of the world to see.
But there are some things you should not post on the internet
Tickets for events
A concert or a sporting event? It is generally not a good idea to post photos of your tickets on social media.
Why; Almost all tickets have a barcode scanned on the portal to allow entry to the event. It is very easy to copy these barcodes from one photo to the next use them to create a ticket just like yours.
Credit and debit cards
It may be obvious, but it happens more than you think. For example, this Twitter account.
It may seem exciting to share a photo of your new credit card, but anyone can use the card numbers to buy something online.
If you want to post a photo of your new credit card at social media, take some time to cover all the numbers.
The boarding pass may look pretty innocent, but it has a barcode and the numbers can say a lot. Think before you post a photo.
The boarding pass of your airline has a lot of information not just for the flight itself. Using some of this information, someone could access your entire account.
With just your last name and registration number, you can access information such as someone's phone number and any booked future flights. In addition, it allows access to someone to change your seats, as well as cancel any future flights.
Therefore, if you want to publish your boarding pass to social, it would be good to hide some information (unique barcodes and numbers)
Photos on your desk
It may seem safe to post a photo of your office, but it may contain too much information about your company or even your own.
Posts on your screen or various invoices and notes in your office may seem harmless, but someone malicious could pick them up and look up account numbers, passwords, specific names and more.
The address of your home
Perhaps the most important of your personal information is your home address. Of course, many of your friends and family know where you live, but not everyone needs to know. Unfortunately, it is very easy to give your address by mistake.
The most common mistake I see is posting photos of homes on social media (either because they were renovated, or just because someone is proud of their home) and the number is displayed on the wall, along with the street.
The number may seem harmless, but if someone knows what city you live in (which you usually mention in your profile) they can easily look up a bunch of addresses in that city starting with your street number and then using Google Street View for confirmation.
Of course you can post all of the above on social. But every time you post one of the above, take some time to check again that there is nothing unique or personal about what you are sharing.
