DALLAS (AP) — The Latest on a coordinated ransomware attack affecting Texas cities (all times local):
Officials say some of the 22 Texas cities that were targeted by a coordinated ransomware attack have recovered and are operating normally.
The Texas Department of Information Resources made the announcement on Tuesday in a news release in which it also lowered the number of cities that were attacked from 23 to 22.
A department spokesman declined to provide more detail.
Authorities believe all of the attacks originated from a single source.
The state has not identified the affected cities or said whether any of the agencies have paid a ransom. The FBI and other federal agencies are involved.
Officials in at least two cities — Borger and Keene — have said they were among those targeted.
Texas authorities say more than 20 local governments are facing a coordinated ransomware attack.
