HVAC and IT System Down at Lufkin Independent School District

June 1, 2022


Several internet systems of Lufkin ISD down due to a ransomware attack. The district realized it had been attacked Saturday morning, according to Sheila Adams, executive director of communications and public relations. School operations that were affected include HVAC at some campuses and Skyward, a school management software. The school announced the HVAC systems were operational again by 2:45 p.m. Tuesday afternoon, 3 days after the attack.

"While its cybersecurity program appears to have worked, leadership does not know for sure if any data was compromised. The district also does not currently know how or why the attack happened as it is still under investigation." Adams said.
