A business email compromise (BEC), sometimes referred to as an email account compromise, relies on the fact that many of us use email to conduct business.
In a BEC scam, criminals send an email which may impersonate a university leader, colleague or a campus service. Some examples include:
- A university leader asks an assistant to purchase gift cards for employee rewards. They may ask for the serial numbers so the gift cards can be emailed immediately.
- A colleague asks if you’re available and asks for your cell phone number.
- An invoice scam where the email impersonates a vendor and requests an update to their mailing address.
In all of these cases, the criminal has spoofed an email address using a slight variation to fool victims into believing the email is legitimate.
Here is an example:
Recognizing BEC email
You can recognize a BEC email by some of the classic signs of a phishing email (Source: it.wisc.edu):
- The displayed name in the email From: line is someone you know but the sending address is from a free email service, often including wisc.edu in the account name (eg. email@example.com).
- The tone of the email conveys a sense of urgency.
- It contains a request for your cell phone number, so the impersonator can shift from email to SMS text messages.
Here is an example:
What to do if you receive a BEC email message
If you are ever unsure whether an email message is legitimate, DO NOT RESPOND to it! Instead, contact the DoIT Help Desk (Source: kb.wisc.edu) and ask for advice.

Tips for leadership
Help protect the university and the people in your team, department, unit or division from BEC email scams. Establish ahead of time how:
- Purchases are to be made and by whom
- You will normally communicate, e.g., only from your @wisc.edu email
- Requests can be verified and by whom
