If you are running a public, public profile, you need to be very careful about what data you publish. For example, tickets and boarding passes for a plane should not be posted on social networks, warned Sergey Nikitin, deputy head of the Group-IB computer forensics laboratory. The information that is indicated on them makes it possible to access the personal account on the airline's website, where passport data, e-mail and the number of the loyalty program participant are stored, the expert explained in an interview with Sputnik radio.
“With the help of a boarding pass, you can find out a person’s personal data, enter your personal account on the airline’s website, cancel a reservation for some hooligan reason, or transfer a person to another place, for example, to the toilet”, - said Sergey Nikitin.
You should also not post publicly available concert tickets, the expert advises: "Now almost all concert tickets are QR-codes, and they are disposable. This means that anyone can take your ticket and go through it, but you are no longer you can, because there it is enough to read the code, and you will not prove anything to anyone".
You should also be careful about publishing geotagged photos: “There are criminal groups that geolocate, for example, your vacations and are engaged in burglary. They can also track unusual expensive cars and the places where they park. If you take such geotagged photos, it makes life much easier for attackers".
If you want to share such things, get yourself a private social media account that is visible only to those you trust completely: there you can allow yourself more.
