Tyler Technologies, the self-proclaimed largest provider of US public sector software and technology services, is struggling with a cyberattack that disrupted many of its operations.
As of yesterday, the official website tylertech.com is offline, and a maintenance notice greets users accessing the page:
“Our Tyler Technologies corporate website is temporarily unavailable. We are aware of the issue and are working to bring the site back online. Please check back soon.”
The Texas-based company offers end-to-end management solutions to over 15,000 government offices across all US states, Canada, the Caribbean and Australia.
According to a statement released by Chief Information Officer Matt Bieri, the company discovered an unauthorized party gained access to internal phone and information technology systems on September 23.
“Early this morning, we became aware that an unauthorized intruder had disrupted access to some of our internal systems,” Bieri said in an email sent to Tyler Technology clients.
“Upon discovery and out of an abundance of caution, we shut down points of access to external systems and immediately began investigating and remediating the problem. We have since engaged outside IT security and forensics experts to conduct a detailed review and help us securely restore affected equipment. We are implementing enhanced monitoring systems, and we have notified law enforcement.”
His statement suggests that the attack was limited to their internal systems only, with no customer data impacted by the intrusion.
“At this time and based on the evidence available to us to-date, all indications are that the impact of this incident is limited to our internal network and phone systems,” Bieri added. “We currently have no reason to believe that any client data, client servers, or hosted systems were affected.”
According to BleepingComputer, RansomExx ransomware operators are responsible for the attack on Tyler Technologies. The gang has been linked to recent attacks on the Texas Department of Transportation (TxDOT) and Konica Minolta.
Time will tell if the intrusion was indeed just limited to Tyler’s internal systems. Although RansomExx operators have not set up a data leak page showcasing their latest victims, the possibility of data exfiltration should not be excluded.
