Total Defense Security Tip of the Day

Vacation mode on: keep your Gmail auto-replies short & sweet for security!

You've booked your flights, packed your bags, and you're ready to escape to paradise! When you're heading off on vacation, setting up an automatic email reply is super smart. It lets people know you're away and when they can expect a response. But here's a crucial cybersecurity tip: don't overshare in your "out of office" message!

Think of your vacation responder as a robot answering your email. It's polite, efficient, but it's not very discerning. While you might be super careful about spotting a sophisticated phishing attempt that somehow slips past your spam filter, your auto-responder isn't going to be so picky. It'll reply to everyone who emails you, including scammers and spammers, and any information you put in there becomes public knowledge to anyone who sends you an email.

The Risks of Oversharing in Your Auto-Reply:

  • Telling Burglars You're Away: Announcing "I'm on a two-week trip to Hawaii!" is basically putting a "House is Empty!" sign on your front lawn. Cybercriminals might share this information with real-world criminals.
  • Providing Phishing Clues: Scammers thrive on personal details. If they know you're out of the office, they might craft more believable phishing emails pretending to be from your boss, a colleague, or a vendor, asking for "urgent" actions while you're unreachable.
  • Confirming Your Active Email: Every auto-reply confirms that your email address is active, making you a more attractive target for future spam and phishing attempts.
  • Revealing Internal Company Info: For business emails, revealing too much about internal roles or your company's hierarchy could give attackers useful intel for targeted attacks.

How to Set Up a Secure Vacation Responder in Gmail:

Setting up your auto-reply in Gmail is easy, and making it secure is even simpler!

  1. Open Gmail: Go to your Gmail inbox in your web browser.
  2. Access Settings: Click on the gear icon (⚙️) in the top right corner.
  3. See All Settings: From the quick menu that appears, click on "See all settings."
  4. Navigate to General: Make sure you're on the "General" tab (it's usually the default).
  5. Scroll to Vacation Responder: Scroll down until you find the "Vacation responder" section.
  6. Turn On Vacation Responder: Select the "Vacation responder on" option.
  7. Set Your Dates: Choose the "First day" and "Last day" for your absence.
  8. Craft Your Message (Keep it Minimal!):
    • Subject: Keep it simple, like "Out of Office" or "Away from Email."
    • Body: This is where you keep it brief.
      • Good examples: "Thank you for your email. I am currently out of the office and will respond to your message on [Date of Return]." or "I will be out of the office from [Start Date] to [End Date] and will have limited access to email. I will respond as soon as possible upon my return."
      • Avoid: Specific travel plans, personal reasons for being away, or alternative contact information unless it's a dedicated work emergency contact you trust.
  9. Decide Who Gets the Reply:
    • "Only send a response to people in my Contacts": For personal accounts, this is often the safest option as it limits replies to known senders.
    • "Only send a response to people in my organization": If this is a work account, this is usually the best choice.
    • "Send a response only to people I know": Gmail has other ways to specify.
  10. Save Changes: Don't forget to scroll to the very bottom of the page and click "Save Changes."

By keeping your automatic email replies short, sweet, and to the point, you're informing your contacts without giving away sensitive information to potential bad actors. Enjoy your vacation, knowing your inbox is both responsive and secure!
