The University of Minnesota on Thursday confirmed that a hacker "likely gained unauthorized access" to three decades' worth of sensitive information pertaining to applicants, students and employees.
The exact nature of the information accessed varied depending on the person's connection to the university, but the list of data obtained included things like dates of birth, Social Security numbers and passport information, according to a U news release. The university said its investigation "showed no evidence that donation, medical treatment, password, or credit card information was in the database" that was accessed.
The disclosure comes two months after the Cyber Express, a news site focusing on cybersecurity issues, published a report outlining a hacker's claims to have accessed some 7 million Social Security numbers dating to 1989. The report said the hacker accessed the university's data warehouse to analyze the effects of affirmative action in the wake of a recent U.S. Supreme Court ruling that limits the consideration of race in college admissions.
The university is facing six lawsuits from former students, employees and others who claim the U didn't do enough to protect their sensitive data or to promptly notify them of the breach. Some of the university's initial responses to those suits are due in the coming days.
"Obviously, this is a very serious breach. We think it implicates a lot of serious concerns about data security and data retention," said Brian Gudmundson, a lead attorney on one of the lawsuits. "We look forward to getting to the bottom of it and making sure that there is redress for the people who are impacted."
The university has said it hired an outside firm to help investigate the hacker's claims after learning of them July 21. On Thursday, the U released some details of that probe.
The university said it believes the incident "potentially affected" people who applied to the university, enrolled, worked for the university or participated in university programs between 1989 and August 2021. As a result of the investigation, the U believes the data was accessed in 2021, according to spokesperson Jake Ricker.
The breach is also being investigated by the Minnesota Bureau of Criminal Apprehension, and the FBI's Minneapolis office has said it is "aware of the situation."
