Public Sector Mega-Vendor Tyler Technologies Says It Was Hacked

Tyler Technologies, a major U.S. provider of public-sector software (including the widely used MUNIS ERP), reported unauthorized access to its internal IT and phone systems—an intrusion that disrupted services and is possibly ransomware-related. The company says client data and hosted systems appear unaffected, but security experts warn of long adversary dwell times, credential risk given Tyler's deep municipal access and lack of MFA in MUNIS, and advise force-resetting passwords and reviewing Tyler support account logs.
