They denied providing specific details of the ransomware or the name of the departments and towns affected but said the systems were offline and are now being handled by response teams for restoration.
Investigation on the matter is underway
As the response teams continue to work on the affected systems, the FBI and Texas DIR are investigating the case in hopes of tracking down the culprit.
It is not exactly clear how much money the attacker asked for, but a spokesperson from the Texas department suggested they were not aware of any department agreeing to pay up the asked amount.
More details likely to be revealed later
The authorities are expected to provide more details about the ransomware and the damage once the systems are restored.
However, the fact that a lone actor was able to compromise 22 government systems is enough to show that cyber-criminals have become sophisticated enough to carry out bulk attacks.
Notably, before this, over 22 other US cities have been targeted in similar kind of attacks.
