Description
On September 13, 2020, Guilford Technical Community College (GTCC) in North Carolina experienced unauthorized access to its network, later identified as a ransomware attack. The college responded by closing all campuses on September 14 to contain the breach and evaluate its scope. This shutdown disrupted campus operations and critical online services, including WebAdvisor and Navigate, which handle student enrollment and academic advising. Multiple college offices suspended operations during the incident. GTCC announced plans to resume in-person classes on September 21, indicating a week-long disruption to academic activities. The attack coincided with network outages affecting institutional systems, though the college did not initially disclose whether data exfiltration occurred.

GTCC appeared on DoppelPaymer’s ransomware leak site, suggesting attackers claimed possession of stolen data, though no specific evidence or data categories were publicly verified. This incident followed a similar ransomware attack on Greenville Technical College in South Carolina, where threat actors from the Avaddon group allegedly exfiltrated information before the college’s listing vanished from leak sites. Both technical colleges faced operational paralysis from ransomware, though no confirmed link between the attacks was established. GTCC removed its initial public notice about the incident, which had described service disruptions and containment efforts. The college provided no further updates on investigation outcomes, ransom demands, or data compromise verification at the time of reporting.
