Your Vacation Auto-Reply Might Be A Hacker’s Favorite E-mail

June 16, 2025

You set it. You forget it. You head out on vacation—and your inbox starts replying:

"Hi! I'm out of the office until [date]. For urgent matters, contact [name] at [email]."

Seems harmless, right?

To a cybercriminal, it's a goldmine.

That simple auto-reply reveals:

  • Your name and title

  • When you're unreachable

  • Who's covering for you (and their contact info)

  • Internal structure

  • Even where you are ("Attending a conference in Las Vegas…")

This info helps hackers do two things:

  1. Time their attack - You're gone and less likely to notice suspicious activity.

  2. Target precisely - They know who to impersonate, and who to trick.

Perfect conditions for a phishing or business email compromise (BEC) attack.

How the Scam Unfolds

  1. Your auto-reply gets triggered.

  2. A hacker impersonates you—or the contact listed.

  3. A fake, urgent email goes out: "Can you wire $45,000 to this vendor?"

  4. A well-meaning coworker acts fast… and falls for it.

  5. You come back to a financial mess.

This is especially dangerous for executives and sales staff who travel frequently and rely on others to handle emails.

How to Write Safer Auto-Replies (and Stay Protected)

  1. Keep It Generic
    Avoid names and details.
    "I'm currently away and will respond upon my return. For assistance, please contact our main line at [main contact info]."

  2. Train Your Team
    Never trust urgent email requests involving money or data.
    Always verify through a second method—like a phone call.

  3. Strengthen Your Email Security
    Use anti-spoofing, filters, and domain protection tools to block impersonation attempts.

  4. Enable MFA Everywhere
    Even if passwords are stolen, MFA can block access.

  5. Partner with a Proactive IT Team
    We monitor logins, detect phishing attempts, and flag suspicious behavior before it causes damage.
