Cyber Incident Victim: University of Minnesota
Date:
Aug 2015
Location:
United States of America
Summary
A hacker known as JM511 compromised multiple universities through SQL injection and cross-site scripting vulnerabilities, including the University of Minnesota. The attacker publicly notified the institution via social media, sharing links to vulnerable URLs but without evidence of exfiltrated personal data from this specific breach. Impacts across targeted universities involved exposed credentials—such as user IDs, usernames, and both hashed and plain-text passwords—with compromised systems running outdated web technologies like Apache and MySQL. JM511 claimed prior warnings to some institutions before attacks, though no data dump was confirmed for Minnesota at the time of reporting.

Description
In August 2015, a hacker using the alias JM511 conducted a series of cyberattacks targeting multiple American universities, including the University of Minnesota, UCLA, Western Governor’s University, DePaul University, and Northern Illinois University. The attacker employed SQL injection and cross-site scripting (XSS) vulnerabilities to compromise university systems, publicly disclosing the breaches via Twitter notifications that included links to the vulnerable URLs exploited in the intrusions. JM511’s activities followed a pattern of issuing warnings prior to attacks, as evidenced by UCLA receiving two emailed warnings over a week before their breach. For the University of Minnesota, the hacker’s tweet served as the primary notification of compromise, though no data exfiltration or leaks were confirmed at the time of reporting. The attacker demonstrated technical familiarity by exposing system details in other breaches, such as Apache and PHP versions, MySQL database configurations, and user credentials from compromised servers at UCLA, where tables containing user IDs, usernames, passwords (some plain-text), email addresses, and names were partially dumped.
The immediate impact on the University of Minnesota remained unclear, as JM511 did not release stolen data from the institution, unlike UCLA, where sample records were publicly posted. However, the exposure of vulnerable URLs indicated potential unauthorized access to university systems, raising concerns about data integrity and confidentiality. No information was provided regarding the university’s detection methods, containment actions, or post-incident responses. Broader impacts included operational disruptions at other targeted institutions and heightened scrutiny of SQL injection and XSS vulnerabilities in academic IT infrastructures. JM511’s additional threat to leak data from Southern Illinois University—previously criticized in a 2014 security audit—suggested ongoing risks to higher education institutions with documented security weaknesses. The reliance on social media for breach notifications highlighted challenges in timely incident response coordination between universities’ public communications teams and their IT security departments.
