A detailed out-of-office reply can hand a scammer everything they need to rob your business. You set it once and forget it, and while you're packing, your inbox starts telling every sender something like this:
"Hi there! I'm out of the office until [date]. For urgent matters, please contact [coworker's name and e-mail]."
Convenient, sure. It's also a gift to anyone looking for an easy way in. That tidy little note tells a criminal you're away, who's covering for you, and exactly who to impersonate.
Look at what a typical message gives away:
- Your name and title
- The dates you're unavailable
- Backup contacts and their e-mail addresses
- How your team is structured and who reports to whom
- Sometimes even why you're gone, like "I'm at a conference in Chicago."
That hands a criminal two things at once. First, timing: they know you're away and won't notice anything odd for a week. Second, targeting: they know who to pose as and who to hit. Put those together and you've got the setup for a phishing or business e-mail compromise (BEC) attack.
How the scam plays out
Your auto-reply goes out. A scammer reads it and impersonates you or the backup contact you named. They send an "urgent" e-mail asking for a wire transfer, a password, or a sensitive document. Your coworker, caught off guard, assumes it's real. You come back from vacation to learn someone sent $45,000 to "a vendor."
This happens more often than people think, and it's worse for companies whose people travel a lot. If your executives or sales team are on the road and an assistant or office admin handles their inbox while they're gone, the conditions line up for a scammer:
- The admin is fielding e-mail from several people at once
- They're used to handling payments, documents, and sensitive requests
- They're moving fast and trusting whoever they think wrote the message
One convincing fake gets through, and now you're cleaning up a fraud loss or a breach.
Keep the auto-reply, just stop oversharing
You don't have to drop out-of-office replies. You just have to write them carefully and back them up with a few habits.
Keep it vague. Drop the itinerary and don't name who's covering for you unless you truly have to. Something like this is plenty: "I'm currently out of the office and will respond when I return. If you need immediate assistance, please contact our main office at [main contact info]."
Train your team to slow down. Two rules cover most of it. Never act on an urgent money or data request from e-mail alone. Always confirm anything unusual on a second channel, like a quick phone call to a number you already have.
Put e-mail security tools to work. Good e-mail filters, anti-spoofing, and domain protection stop most impersonation attempts before anyone reads them.
Turn on MFA everywhere. Multifactor authentication on every e-mail account means a stolen password isn't enough to get in.
Have someone watching the account. A good IT and cybersecurity partner catches odd login attempts, phishing, and abnormal behavior before it turns into a loss.
