Most Common Cyberthreats To Municipalities And Special Districts In 2025

Cyberattacks are occurring at an ever-increasing rate, and municipalities and special districts in Los Angeles and Ventura Counties are not immune to them. For example, the Los Angeles Unified School District suffered from multiple cyberattacks in January and September 2022, and another in June 2024. These threats can disrupt public services and expose sensitive data. 

If you’re a local government official, you need to know about these cyberthreats so you can protect your organization against them.

Ransomware attacks

In a ransomware attack, cybercriminals encrypt your data, rendering it inaccessible until a ransom is paid. These attacks have the potential to cripple public services, disrupting essential operations and causing widespread service outages.

How to defend against this cyberthreat:

• Always keep offline backups of your data so you can recover it without having to pay the ransom.
• Train your employees to recognize phishing scams, which are commonly exploited as entry points for ransomware attacks.
• Use endpoint detection and response solutions to effectively monitor, identify, and address suspicious activities on endpoints such as laptops, desktops, servers, and mobile devices in real time. 

Social engineering and phishing

Phishing is a form of social engineering where cybercriminals pose as trusted sources to deceive victims into revealing their credentials or unintentionally installing malware on their devices. What makes social engineering particularly dangerous is its reliance on exploiting human psychology rather than technical vulnerabilities, making it a subtle yet highly effective attack method.

How to defend against this cyberthreat:

• Conduct regular cybersecurity training to keep employees up to date on the latest phishing tactics.
• Enable multifactor authentication so that users will need to present more than one proof of their identity before they gain access to accounts. 
• Apply advanced email filtering systems that recognize and reject unauthorized users who are trying to break into your inbox.

Insider threats

Data breaches caused by employees can stem from either malicious intent, such as the actions of a disgruntled worker, or simple human error. Since employees have direct access to critical systems, their actions — whether deliberate or accidental — can cause significant damage.

How to defend against this cyberthreat:

• Conduct thorough screening and background checks during the hiring process.
• Restrict employee access to sensitive data, ensuring they only access information relevant to their responsibilities.
• Develop a robust system to monitor user activity and identify any unusual behavior. 

Supply chain attacks

Thousands of municipalities and special districts rely on third-party vendors to deliver essential services. Vendors with weak security measures can expose municipal systems to significant vulnerabilities, leaving them open to exploitation by attackers.

How to defend against this cyberthreat:

• Before you work with potential vendors, vet their cybersecurity practices.
• Have your vendors perform regular security audits and provide certificates of compliance.
• Provide vendors access only to the information they need to carry out their jobs.

Legacy systems

Legacy systems, often outdated and lacking regular updates or support, are highly vulnerable to cybersecurity threats, making them an attractive target for cybercriminals. 

How to defend against this cyberthreat:

• Keep your systems updated with the latest security patches.  
• Modernize your infrastructure by budgeting for the replacement of outdated tools.  
• Regularly assess your systems for potential security gaps to stay ahead of vulnerabilities. 

Cloud misconfigurations

Moving to the cloud may seem straightforward, but it comes with its challenges. For instance, misconfigurations can expose sensitive data or grant unauthorized access to malicious actors, posing significant cybersecurity risks. 

How to defend against this cyberthreat:

• Follow the best practices for cloud configuration to minimize vulnerabilities. 
• Use automation tools that can detect and correct configuration mistakes in real time. 
• Conduct periodic security audits to identify and address misconfigurations promptly.  

Vulnerabilities in the Internet of Things

Internet of Things (IoT) devices are connected through the cloud, exchanging data with one another. When IoT devices that are integrated with public infrastructure lack proper security features, they can expose critical systems to heightened cyberthreats. 

How to defend against this cyberthreat:

• Use encryption and secure your IoT devices with strong, unique passwords. 
• Where possible, isolate IoT devices from mission-critical systems through network segmentation. 
• Regularly update the firmware of your IoT devices to patch vulnerabilities and prevent exploitation. 

Next step: Partner with a managed IT services provider

As cyberthreats become increasingly sophisticated, municipalities and special districts must adapt their cybersecurity strategies to stay protected. However, managing cybersecurity can be complex and often diverts valuable resources from core operations.

This is why working alongside a managed IT services provider (MSP) like AllConnected can be beneficial to a local government. An experienced MSP takes on the responsibility of monitoring and managing your IT systems, enabling local governments to focus on their primary mission of serving their communities.
