Clarksville Independent School District warned Nov. 26, 2025, that all district computers and its network were having major problems and told staff and students to stop using connected devices. A later Interlock victim listing claimed data theft, but the district had not confirmed ransomware, a cyber cause for the outage or a connection between the two in the December report.
The incident is confirmed to be cyber-related, but the specific attack mechanism is unknown.
The incident is cyber-related, but available evidence does not establish whether or how data was affected.

DysruptionHub assesses with medium confidence that Clarksville Independent School District’s November network disruption may have been cyber-related. The district’s Nov. 26 technology update says all connected computers and the district network were affected, warns against use, and says recovery could take days. Our Dec. 19 report records a later Interlock victim listing. The district did not publicly confirm the listing, ransomware or a causal link in the reviewed material.
The districtwide network problem interrupted access to school computers and affected dual-credit coursework deadlines, prompting coordination with Paris Junior College. The available update did not establish school closures or the exact duration of the outage.
The Nov. 26 notice said recovery might last into the following week. No reviewed district statement establishes a restoration date or forensic conclusion. Because no later operational disruption was documented in the reviewed sources, this retrospective record is presumed resolved without a verified all-clear.
The district’s own notice confirms material network disruption. The Interlock listing is an unverified external claim of intrusion and data theft. A separate later breach-filing summary references a November event, but the primary filing and its connection to this outage were not verified; it is not used to confirm this record.
Cyber cause of the outage, actor linkage, data impact, initial access and restoration date remain unresolved.
Interlock listed Clarksville ISD as a purported victim and alleged theft of personal and financial information, as recorded by ransomware.live and our Dec. 19 report. The district confirmed a serious network outage but has not confirmed Interlock’s claim, ransomware, data theft or a causal link to that outage.
We reported Clarksville ISD’s Nov. 26 districtwide technology outage and the later Interlock listing, emphasizing that ransomware and a causal link were not confirmed.
The district said all computers and its network were experiencing significant difficulties, told users not to use connected devices, and worked with Region 8 ESC on recovery.
