At the beginning of this month, I took an appointment to get the passport, the date was set for the 24 of August. The 23 of August I received a spam email mimicking the government office which among other things also releases passports. The e-mail which I used for all the procedure is a more personal e-mail which I handle more carefully than the other.
A friend of mine went to the postal office to do some things and the day after got a spam email mimicking that office.
I am sure that in my case, the first e-mail should not have been hacked and from the perspective of the second e-mail, no one could have known of my appointment. The only thing I can think about is some GPS data been leaked. How this kind of attacks works?
