🎯 Why Cybercriminals Love OOO Messages
A typical OOO message can include:
-
Your full name and title
-
Exact dates you're unavailable
-
Names and emails of coworkers
-
Internal structures or delegation of info
-
Even travel details ("At a trade show in Chicago...")
This data hands attackers two big advantages:
-
Timing - They know you're distracted or unavailable.
-
Targeting - They know who to impersonate and who to target next.
🎭 How the Scam Works
It's called a Business Email Compromise (BEC). Here's how it usually goes:
-
Your auto-reply goes out to someone suspicious.
-
The hacker impersonates you or your backup contact.
-
They send an urgent email requesting sensitive info, login credentials, or a wire transfer.
-
Your team member, unaware and trying to be helpful, complies.
-
You return to a financial or data disaster.
This happens more often than you think, especially in industries where execs and sales teams travel frequently.
🛡️ How to Protect Your Business from OOO Exploits
You don't need to stop using OOO messages, just use them smartly and layer in protection:
1. ✂️ Keep It Vague
Avoid naming coworkers or detailing travel plans.
Safer Version:
"I'm currently out of the office and will reply when I return. For immediate needs, please contact our main office at [main contact info]."
2. 🧠 Train Your Team
Make sure staff know to:
-
Never act on urgent requests via email without verification.
-
Always double-check through a phone call or internal chat.
3. 🔐 Implement Strong Email Security
Use email filtering, anti-spoofing measures, and domain monitoring tools to stop impersonation attacks in their tracks.
4. 🔑 Use MFA (Everywhere!)
Multi-Factor Authentication adds a crucial second layer. Even if a password leaks, it keeps hackers out.
5. 👁️ Work with a Proactive IT Partner
A true cybersecurity partner will monitor logins, flag suspicious activity, and act before damage is done.
