Many of us love to travel. Against the background of positive feelings from the upcoming flight, being in the waiting area, enjoying fresh coffee, we ourselves may not even be aware of it making a big mistake.
As soon as you decide to post a colorful post on social networks with a photo of a part of the ticket that is carelessly lying under a saucer of your coffee or covered by the cover of your passport, then you should not rush to do it. Yes, showing subscribers that you are going to the sea is cool, but not at such a cost.
It is enough for an attacker to see your ticket number and surname on the photo, and you have a chance not to fly anywhere.
Why? It's simple.
On the websites of airlines there is a ticket management function, for activation of which it is enough to indicate the ticket number and the passenger's surname. After that, the attacker will be able to view passport data and control your flight (canceling the flight, changing the date of departure, etc.).
