Tyler Technologies Ransomware Attack: $1.5M In Lost Revenue

Government software and IT service provider Tyler Technologies ($TYL) lost about $1.5 million in services revenue because of a ransomware attack in September, the company disclosed in its Q3 2020 earnings report on November 4.

MSSP Alert first reported details about the Tyler Technologies ransomware attack on September 25. After the attack, Tyler Technologies warned that some of its customers had reported suspicious logins, Reuters notes.

Tyler hired third-party cybersecurity investigators to assist with the recovery efforts, though the government software provider did not disclose digital forensics firm(s) by name or any specific MSSP (managed security services provider) engagements.

Tyler provides software services for everything from jail and court management systems to payroll, human resources, tax and bill collection and land records, the Associated Press notes. Amid the attack, Tyler was quick to point out that none of its products are a system of record for voting or election-related activities.

The company’s public sector software addresses such government needs as:

  • appraisal and tax software and services;
  • software for courts and justice agencies;
  • enterprise financial software systems;
  • planning/regulatory/maintenance software;
  • public safety software;
  • records/document management software solutions; and
  • transportation software solutions for schools.

Tyler initially was quick to point out that those customer applications were not impacted by the attack. But the company on September 26 warned that some customers have reported suspicious logins in recent days.
