But this absence of basic travel cybersecurity is a problem. Email is the number one threat vector for socially engineered attacks. An automatic reply message not only sends the information to designated contacts, but it also bounces back to people who send phishing emails. Threat actors use any details found in OOO messages to craft targeted social engineering messages. Well-targeted messages build trust that threat actors take advantage of.
Hijacking this with a question- what do you do when you no longer have an co-workers to serve as an out of office contact? I find myself putting up the OOO less and less, because there’s no one left to respond to anything in my absence (beyond my supervisor who has no knowledge of how to do the tasks of my job).

Note: Outlook does not attach your signature when it sends automatic replies. If you have a signature, you might want to paste it below your message. If you don’t have one, learn how to add an email signature in Outlook.
