Knottingham Trent University Data Breach

ShadowByt3$ listed Knottingham Trent University on its dark web leak portal on August 25, 2026. This listing was identified through SOCRadar’s Dark Web Monitoring service. Knottingham Trent University is a UK public research university serving tens of thousands of students across a broad range of disciplines, with substantial digital infrastructure supporting learning, research, and staff operations. The listing places the institution among a small but growing set of UK education targets claimed by ShadowByt3$, suggesting a pattern of focused targeting rather than opportunistic attacks. ShadowByt3$ is an emerging threat actor, having claimed three other victims within the 60-day period preceding this listing. These prior victims spanned the Education, Technology, and Agriculture sectors, primarily located in the United Kingdom and Indonesia. Other organizations with profiles similar to Knottingham Trent University that have been targeted include A-Plus Software Limited and Sinar Mas Agribusiness and Food (Golden Agri-Resources). This concentration on the UK and the education sector suggests a deliberate targeting posture by ShadowByt3$ rather than random selection.

SOCRadar’s stealer-log query for ntu.ac[.]uk returned 26 records. Ten of these records consist of employee credentials, specifically @ntu.ac[.]uk and @my.ntu.ac[.]uk usernames that authenticated against target-owned endpoints. Notable high-value endpoints identified include the university’s network-storage and file-share infrastructure, a password-management and identity-synchronization service, and the student applicant portal. An additional record linked a corporate identity to a third-party SaaS platform. A noteworthy signal was the presence of a record inserted in March 2025 but logged in August 2026, which could indicate either delayed stealer-log surfacing or a credential that remained unrotated for approximately 17 months. The freshness window for these detected credentials spans from March 11, 2025, to August 26, 2026. The presence of employee credentials on file-share infrastructure and a password-management portal poses a significant risk. A compromised password manager entry could potentially cascade to numerous internal systems, providing access far beyond what a typical stealer-log sample might reveal. The fact that the observed freshness window closes on August 26, the day after the ShadowByt3$ listing, suggests that these records were still being generated at the time of publication. While these credentials have not been definitively confirmed as the entry point used by ShadowByt3$, the observed pattern is consistent with the pre-deployment access phase commonly seen in this class of incident. CTI teams should prioritize immediate credential rotation for all identified accounts. Additionally, a thorough review of file-share access logs and endpoint forensics on affected devices are recommended to identify the full scope of any potential compromise. Continued dark web and stealer-log monitoring is advisable to detect any further related activity.
