When they first heard that someone had bragged in a blog post about hacking into their website, officials at Metropolitan State University weren't sure what to make of it.
The hacker, they were told, appeared to be a teenager from Australia who claimed to have attacked Metro State's website, and dozens of others, on a whim.
Within a week, they discovered that it was no idle boast.
On Friday, the university announced that it was investigating a security breach that could have exposed personal information about an unknown number of students, faculty and staff.
In a campuswide e-mail, interim president Devinder Malhotra disclosed Friday that a university database had been breached, and that people on campus should be on the alert for identity theft.
"We do not believe this server contained any financial data or credit card information," he wrote, but it did include personal information, including employee Social Security numbers.
Officials say they learned about the problem Jan. 2, when a cybersecurity service notified the university about the hacker's blog post.
"This particular person was claiming to have hacked into 75 different websites, and we were just one of those," said Anne Sonnee, interim vice president for communications.
