Phishing Email Summary


Description of Phishing Scam:

This phish attempts to steal login credentials and Duo login codes by redirecting recipients to a fake login page. The phish and login page steal U-M branding and use forged U-M email addresses to appear more realistic.

The first part of this phish is an email claiming that your Duo token is "out of sync." The email uses forged U-M addresses for the Team Dynamix system. This gives the appearance of the email having originated with a known U-M ticketing/Help Desk system familiar to many recipients. The reply-to address is also set to Team Dynamix. Links in the email may appear to be to weblogin, but they are also fakes.

The second part of the phish is a fake weblogin page that also steals U-M branding and asks users to enter credentials and to also supply Duo codes. A first attempt to enter credentials may result in an error and redirection to a second phishing page that claims to be the "central authentication" page. This asks the user to put in a Duo code.

How to protect yourself:

Because branding can be copied and stolen and email addresses faked, diligently checking the URL of a login page is the best way to avoid this and many scams. Text in the link may say, BUT the URL of the page it takes you to does not match. In the screen shots below, you can see that the email uses "weblogin" as text with a hyperlink pointing to a fake address starting with "academic portal."

When logging in, always check that the URL on the page you arrive at says "" with nothing before it. Note that if you have already authenticated to weblogin, going to that address should send you to Wolverine Access.

What to do if caught by this scam: Anyone who thinks they may have been a victim of this scam should immediately change their password and unenroll then re-enroll with Duo.
