Victim: City of Tulsa, Oklahoma

Tulsa’s computer security system identified the attack and shut down the system before it was infiltrated.
The attack, discovered earlier this month, was similar to the ransomware attack that shut down the Colonial Pipeline for days, according to Tulsa Chief Information Officer Michael Dellinger.
