TULSA, Oklahoma – City leaders have warned residents about a ransomware attack that led to thousands of city files being leaked on the dark web.

The City of Tulsa learned that the hackers responsible for a ransomware attack on the city in May 2021 had shared more than 18,000 files on the dark web.

According to city officials, most of the files were police citations and internal department files.


However, police citations do contain personal information like name, date of birth, address, and driver’s license number. But the Police citations do not include Social Security numbers.

At the moment, no other files are known to have been shared.

City officials, say that anyone who has filed a police report, received a police citation, made a payment with the city, or interacted with the city in any way where personal identifying information was shared is being asked to start monitoring their credit report.

Residents are asked to:

  • Monitor financial accounts and credit reports
  • Get with credit/debit card companies to issue a fraud alert
  • Change passwords to personal accounts
  • Take additional authentication measures in all personal accounts and applications
  • The city and federal authorities are investigating the data breach.
