The City of Dallas, Texas, has suffered a ransomware attack, causing it to shut down some of its IT systems to prevent the attack's spread. Dallas is the ninth largest city in the United States, with a population of approximately 2.6 million people, according to US census data.

Local media reported that the City's police communications and IT systems were shut down Monday morning due to a suspected ransomware attack.

Today, FOX 4 confirmed that the disruption was caused by a ransomware attack after obtaining a message sent by the City, shared below.

"Early this morning, the City's security monitoring tools notified our Security Operations Center that a likely ransomware attack had been launched within our environment. Subsequently, we have confirmed that a number of servers have been compromised with ransomware, impacting several functional areas," read a message obtained by Fox 4.

"The team is actively working to isolate the ransomware to prevent its spread, to remove the ransomware from infected servers, and to restore any services currently impacted. Pursuant to the City's Incident Response Plan, the purpose of this message is to provide notification of an established security incident. We will provide further information about the remediation efforts and potential impacts to City services when available."

"At least 29 have been impacted by ransomware this year, with at least 16 of the 29 having had data stolen. Most of the incidents involve smaller governments and Dallas is, I think, the largest city to be hit in quite some time."
