“Because we have received reports of several suspicious logins to client systems, we believe precautionary password resets should be implemented,” the company said.

“If clients haven’t already done so, we strongly recommend that you reset passwords on your remote network access for Tyler staff and the credentials that Tyler personnel would use to access your applications, if applicable.” [emphasis Tyler’s]
