Hundreds of thousands of university email address from Michigan are circulating on the Dark Web.

A report from the Digital Citizens Alliance says millions of stolen emails connected to universities around the country have been found on the web used by criminals.

They say the largest number is from the University of Michigan – more than 122,000 while Michigan State had nearly 116,000 stolen addresses.

Researchers say it's not from a massive data breach, but more likely from breaches at other sites where people have used their school email.
