What do you, as a user, need to know?
Attackers are sending phishing messages in which they impersonate the Rector of Masaryk University. The messages are sent from various external email addresses, such as officepvostmqil@gmail.com or Martin.bares.med@outlook.com, and are designed to appear at first glance as legitimate communication.
The wording of the messages is intended to build trust and prompt the recipient to respond. They are written in both Czech and Slovak, which can further reinforce the impression of normal and credible communication. They typically include a personal greeting, a request for discreet assistance, and an explanation of why the sender cannot make a phone call, for example because they are in a meeting or otherwise busy. Requests for discretion, time pressure, and attempts to discourage verification through another communication channel are all important warning signs.
Pay attention to Microsoft 365 warnings
If the system warns you that you do not usually receive messages from a particular email address, treat this as a reason to verify the sender. In phishing attempts, an unusual external email address may be a key sign that someone is merely impersonating a familiar or trusted person.

Závěr
Phishing messages impersonating the Rector demonstrate how attackers can use a trusted name, personal greetings, and urgent or discreet wording to initiate communication with the recipient. It is therefore important to verify the sender’s actual email address, be cautious of unusual requests, and, if in doubt, confirm the communication through another channel.
