The City of Dallas, Texas, has become the latest target of a ransomware attack. The incident, which took place on Wednesday morning, is currently affecting city services, including the Dallas Police Department's website. In this blog post, we'll discuss the details of the attack, its impact on the city, and the actions taken by officials to mitigate the damage.
The Attack:
The ransomware attack was first detected by the City's security monitoring tools, which alerted the Security Operations Center (SOC). A number of servers were compromised, impacting several functional areas such as the Dallas Police Department website. In response, city officials notified the Mayor and the City Council, and activated the City’s Incident Response Plan (IRP).
The Impact:
As a result of the attack, City Hall network servers went down, and the Dallas Police Department's computer-assisted dispatch system was forced to use its backup radio system to dispatch officers to 911 emergency calls. Fortunately, the Police Department reported no issues or delays in receiving 911 calls or dispatching responding officers. While the City Hall website remained down late Wednesday afternoon, the Dallas Police Department's website was restored.
The Response:
The city is currently assessing the aftermath of the attack, but so far, the impact on the delivery of city services to its residents appears limited. Teams are working to isolate the malware and prevent it from spreading through the city's network. Meanwhile, software vendors are attempting to remove the ransomware from infected servers and restore affected services.
Not the First Attack:
This is not the first ransomware attack to hit Dallas. In December 2022, the Dallas Central Appraisal District was targeted, resulting in its email, website, and servers being shut down for at least a month. The cost to restore services in that attack was $170,000.
