Southeastern Oklahoma State University closed its Durant campus for two days and temporarily took some computer systems offline after reporting a network disruption affecting campus systems.
The university’s public notices reviewed by DysruptionHub described the incident only as a network disruption. KXII, citing the university, was the only source reviewed that attributed it to cybercriminals.
The closure interrupted in-person operations at the public university, which reported 6,012 students enrolled in full or partial fall 2025 terms. KXII reported that the university was investigating with help from third-party experts and working to determine the incident’s nature and scope.
Southeastern first announced the disruption in a Facebook post Thursday, July 30, and closed the campus for the rest of the day. An evening update extended the closure through Friday while information technology staff worked to restore normal operations.
The university did not specify which systems were taken offline.
The nature of the disruption remains unclear. There has been no public confirmation of ransomware, data theft, a ransom demand or law enforcement involvement.

The university disruption comes about 14 months after a ransomware attack on Durant’s city government disrupted online payments and administrative systems. The city later said the attack may have exposed personal and financial information. No connection between the incidents has been reported.
DysruptionHub found no public claim of responsibility as of publication.
The university has not said when it expects to restore normal operations. It did not respond to a request for comment before publication.
