Reports Emerge of Possible Southeastern Oklahoma State University Security Incident
Southeastern Oklahoma State University (SOSU), a public educational institution near the border of Oklahoma and Texas, may have suffered a data breach.
According to an August 19, 2026 post on dark web security site Ransomware.live, hacker group Interlock was behind the suspected attack that reportedly resulted in the exfiltration of student and employee personal data, including more than 90,000 student names, Social Security numbers and student identification numbers. The alleged breach was estimated to have occurred on July 31, 2026.
Also on August 19, DataBreach.com published a searchable database that indexed the information supposedly exposed in the Southeastern Oklahoma State University data breach, which it found to include 582,315 rows containing names, dates of birth, contact information, addresses and Social Security numbers.
Previously, SOSU had reported a network disruption affecting campus systems in a July 30 Facebook post, but the school has not confirmed whether any data was accessed during the incident.
