- The Risk: You create an out-of-office message that contains too much information. This may be helpful to colleagues, but it makes you and the College vulnerable to scammers.
- Safer Practices: Create different out-of-office messages for internal and external audiences. Do not share details such as exact dates, your trip destination, and your office’s leadership structure.
How can an out-of-office message pose a security risk?
Let’s say you’re a manager headed to Cancun for a vacation. You write an out-of-office message that contains:
- The dates of your departure and return
- Contact information for a colleague who will be available in your absence
- Some details about your destination
Most people don’t give this a second thought, but you could potentially be putting the College at serious risk. In the wrong hands, this information can open the door to phishing attacks and financial fraud.
By making this information public, you are unwittingly giving a hacker everything they need to complete a Business Email Compromise (BEC) scam. In BEC attacks, the scammer commits fraud by posing as a senior employee and will attempt to trick an employee into fulfilling a fraudulent request, such as transferring money or accessing confidential data.
Using a slightly modified email address that mirrors yours, a scammer can impersonate you and address your colleague by name. If you provided details about your vacation or conference, they might even mention how great the trip is going to make the request more convincing.
This kind of cyberattack makes up a large part of the cybercrime industry. According to the FBI, American companies have lost $12 billion to BEC attacks. The good news is there are ways to protect yourself and your office.
What are the best practices for an out-of-office message?
Whether you’re taking a personal or business trip, or taking time off for another reason, always remember that information contained in your out-of-office message could be used maliciously.
What you can do:
- Create different out-of-office replies for Trinity recipients and those outside the College. Internal communications can contain more details.
- Avoid sharing personal details.
- Don’t mention your travel destination.
- Don’t provide direct insight into your office’s leadership structure.
- Avoid stating the exact length of your absence.
Remember: When it comes to out-of-office message best practices, less is more.
