Auto-replies are meant to keep things running smoothly while you’re away. A quick “I’m out of office until…” message seems harmless, right? It lets people know you’re unavailable and points them in the right direction.
But here’s the hidden truth: cybercriminals love out-of-office messages.
These seemingly innocuous emails can give hackers exactly what they need to launch a convincing and costly phishing or business email compromise (BEC) attack.
Why Your Auto-Reply Is a Goldmine for Cybercriminals
A typical out-of-office (OOO) message often includes:
- Your name and title
- The dates you’ll be gone
- Who to contact in your absence (name + email)
- The reason you’re unavailable (“I’m attending a conference in New York…”)
This provides hackers with two key pieces of information:
1. You’re not available to monitor or respond to email activity.
2. They know exactly who to impersonate—and who to target.
How the Scam Plays Out
It often goes like this:
- Step 1: Your auto-reply is triggered.
- Step 2: A hacker uses your message to spoof your email or that of your backup contact.
- Step 3: They send an urgent request—usually involving a wire transfer or sensitive document.
- Step 4: The recipient believes it’s legitimate and acts quickly.
- Step 5: You return from vacation to find out $45,000 was transferred to a fraudster.
Why SMBs Are Especially at Risk
For small and mid-sized businesses, this kind of incident can be devastating. It’s even riskier when your team travels often or has assistants managing inboxes. These assistants are juggling multiple requests, often involving sensitive data or money—and one clever fake email is all it takes.
Unlike enterprise corporations, SMBs may not have layers of verification and may rely on trust and speed to get things done. That’s what cybercriminals are counting on.
How To Write a Safer Out-of-Office Reply
Here’s how to reduce risk without ditching your auto-reply entirely:
1. **Keep It Vague** – Don’t disclose your travel plans, exact dates, or internal team roles. If you must list a contact, use a general company email or phone number.
2. **Educate Your Team** – Make sure employees never act on sensitive requests without verifying them through a secondary channel (like a phone call).
3. **Use Strong Email Security** – Implement advanced spam filters, anti-phishing tools, and domain spoofing protection.
4. **Require MFA** – Multifactor authentication prevents access even if a password is compromised.
5. **Partner With a Proactive IT Provider** – Real-time monitoring and threat detection are essential in spotting suspicious activity early.
