You set it. You forget it. And while you’re packing for vacation, your inbox is busy broadcasting:

“I’m out of the office until [date]. For urgent matters, please contact [coworker] at [email].”

Convenient—until cybercriminals see it as an open invitation.

Why Your OOO Reply Is a Gold Mine

A typical out-of-office message often reveals:

  • Your name and title
  • Exact dates you’re away
  • Alternate contacts (with their e-mails)
  • Internal team structure
  • Even your travel location (“At a conference in Chicago…”)

That intel gives hackers two things:

  1. Timing – They know exactly when you’ll be off the grid.
  2. Targeting – They know who to impersonate and when to hit.

How the Scam Plays Out

  1. Your auto-reply goes out.
  2. A hacker mimics you or your backup contact.
  3. They fire off an “urgent” request for a wire transfer, password or sensitive file.
  4. Your coworker, thinking it’s legit, complies.
  5. You return to discover, say, $45,000 wired to “the vendor.”

This isn’t rare—especially when your execs or sales teams are on the move.

Why Traveling Teams Are Especially Vulnerable

  • Personal assistants and admins juggle high-volume emails.
  • They’re used to handling payments and sensitive documents.
  • Under pressure, one convincing phishing email can slip through.

How To Protect Your Business From Auto-Reply Exploits

1. Keep It Vague

Skip granular details.

Good: “I’m currently out of office and will reply when I return. For urgent help, contact our main line at [phone].”
Bad: “I’m in Chicago until Thursday—reach out to Sara at sara@company.com.”

2. Train Your Team

  • Never act on money requests via email alone.
  • Always verify unusual asks through a secondary channel (phone call or video chat).

3. Harden Your E-mail Security

  • Deploy advanced filters and anti-spoofing tools.
  • Lock down your domain against impersonation.

4. Enforce MFA Everywhere

Even if passwords leak, accounts stay locked.

5. Partner With a Proactive IT Team

A true security partner watches logins, flags phishing attempts and alerts you before disaster strikes.
