The 2020 Ransomware Attack
In September 2020, Tyler Technologies disclosed that it had suffered a ransomware attack affecting its internal systems. Tyler Technologies provides software used by thousands of local governments for functions including property tax assessment, court management, public safety dispatching, and financial management. The attack raised concerns about whether the ransomware spread or could spread to client government systems.
Tyler Technologies serves approximately 15,000 government organizations. The potential for a software provider serving this many government entities to be a vector for attacks on critical infrastructure -- including 911 dispatch systems, court records, and public safety databases -- elevated the severity concerns beyond typical ransomware incidents.
Legal Claims and Government Client Impact
Litigation arising from the Tyler Technologies attack involves claims from: government clients who experienced system disruptions or security incidents they attribute to the Tyler attack; third parties whose information in government systems may have been compromised; and potentially government entities seeking to recover operational costs from the disruption.
Establishing causation between Tyler's ransomware incident and specific government client impacts is legally complex -- whether the ransomware spread to client systems and what data was actually compromised requires technical forensic evidence that may still be contested.
Who Qualifies
