No one thinks much about cybersecurity while traveling. However, email security company Tessian warns the out of office message actually plays right into the hands of threat actors and cybercriminals. It’s a social engineering attack vector that no one thinks about. The out of office message is ubiquitous and handy. But if it includes any personal information at all — such as attending a funeral or going out of the country — attackers have all the information they need to impersonate the person who is out of the office, without the attacker having to do any real work.
Ha – I didn’t watch the video but still definitely get the condescension! It’s a LOT of extra explaining and direction when something like, “if you need immediate assistance, please contact Fergus at…” will do. In my opinion, cutesy stuff like this is mildly entertaining at the beginning but gets dumb/annoying shortly thereafter. Not just with OOO messages, but other instances where companies try to make being “cool/funny/laid back” parts of their brand in really obvious ways.

An out of office message shows your professionalism by informing others of your unavailability. Such messages generally include an apology for the inconvenience, a reason for not replying right away, the time the receiver can expect a response and an alternative person they can contact if there is something urgent.
