April 2025 brought Abilene, Texas, into the cybersecurity spotlight. A sudden and severe cyberattack left city servers unresponsive, highlighting a growing crisis affecting municipalities across the state.
As threats evolve, cities must shift from reactive approaches to proactive, strategic defense.
Lessons drawn from Abilene’s experience offer crucial guidance for others facing similar vulnerabilities.

Abilene’s rapid activation of its cyber incident response plan played a key role in containing the damage. City officials moved quickly, following pre-established protocols that minimized disruption to critical public services.
There was no confusion, no hesitation—just execution. That level of preparation is not accidental. It is the result of clear planning, regular training, and executive-level commitment.
Cyberattacks strike without warning. First reactions determine how severe the fallout becomes.
Delays during those initial moments can multiply losses. Confusion exposes cracks that cybercriminals are waiting to exploit. Municipal networks are often interconnected. A delay in isolating compromised systems can turn a small breach into a citywide failure.
Cities must treat cyber incident readiness as an operational necessity, not a technical side project. Every department, IT, emergency management, utilities, law enforcement, must know its responsibilities when the network goes dark.
Role clarity under pressure only happens through routine rehearsal. Written plans mean little if they haven’t been stress-tested under simulated chaos.
A few foundational measures help ensure effective response. Key practices include:
- Establishing a detailed, department-specific incident response plan that outlines who does what during different types of cyber events.
- Designating a clear chain of command for decision-making, with alternates assigned in case of unavailability.
- Running biannual tabletop exercises and full-scale simulations to test readiness, including involvement from elected officials, legal teams, and third-party vendors.
- Maintaining up-to-date emergency contact lists and offline copies of procedures to ensure accessibility during network outages.
- Incorporating lessons learned from drills and real events into revised response strategies.
Lesson #2: Ransomware and Governmental Targeting Are the New Normal
Abilene’s attack didn’t occur in a vacuum. Recent cyber incidents across Texas reveal a pattern: municipalities are now primary targets for ransomware groups.
These groups, including Royal, operate with coordination and purpose, often seeking out government systems due to their perceived vulnerability and high-value data.
Smaller cities often believe attackers will focus on larger urban areas or private-sector companies. That assumption leaves critical systems exposed.
Public institutions manage massive data volumes, payment systems, emergency services, and sensitive infrastructure. Criminal groups know that cities cannot afford long disruptions, making them ideal targets for extortion.
To face this new threat environment, Texas cities must adopt a higher standard of digital security. Basic antivirus and outdated perimeter defenses no longer suffice. Stronger models, proactive monitoring, and constant evaluation of defenses are required.
Steps cities must take include:
- Adopt zero-trust architecture to reduce lateral movement within networks.
- Implement Endpoint Detection and Response (EDR) tools that offer continuous threat monitoring.
- Mandate regular third-party security audits to uncover vulnerabilities before they’re exploited.
- Educate staff continuously to recognize social engineering and phishing attempts.
- Segment networks to isolate critical systems and contain breaches quickly.
Utilize proxy servers to manage and monitor network traffic. A proxy server acts as an intermediary between a user’s device and the internet, forwarding requests and responses.
The setup can enhance security by filtering malicious content, controlling access to resources, and masking internal network structures.
For a detailed explanation, refer to Soax on proxy servers.
Lesson #3: Offline Doesn’t Mean Inoperative, Business Continuity Is Critical
Despite losing access to core digital systems, Abilene’s emergency services remained operational throughout the cyberattack.
City officials made swift adjustments, including pausing utility shutoffs and finding alternative ways to keep key functions moving.
Their ability to pivot quickly demonstrated that operations can still continue under pressure when strong contingency plans are already in place.
Business continuity is not just about backin up files or spinning up replacement servers. It means designing an operational strategy that assumes failure is inevitable and prepares every department to function in its absence.
Planning should focus on maintaining essential services even when networks are down or data is inaccessible. Backup systems alone don’t cover the full spectrum of operational needs.
A complete continuity plan should include:
- Manual processes for mission-critical services like billing, permit issuance, and administrative records
- Redundant communication channels for emergency services, such as radios, backup phone lines, or satellite systems
- Hard copies of emergency procedures accessible to first responders and essential personnel
- Cross-trained staff able to fill multiple roles when automated systems are unavailable
- Clear escalation protocols that activate when digital services are compromised
A single point of digital failure should never derail the delivery of public essentials. Critical services must be shielded by layers of redundancy that bridge the gap during outages.
Lesson #4: Visibility and Transparency Foster Trust
When residents in Abilene learned about the cyberattack, they weren’t left guessing.
Officials delivered prompt updates, using clear, direct language to describe what was known, what had been affected, and what steps were being taken. That level of openness helped manage public reaction and avoided unnecessary panic.
In moments of uncertainty, silence causes more damage than a clear, honest explanation. Uninformed communities become breeding grounds for rumors.
Speculation fills the void when institutions choose secrecy over communication. Instead, transparency calms fears, builds cooperation, and demonstrates leadership during chaos.
Proactive cities prepare communication strategies before any attack happens. Quick and credible messaging requires groundwork, not improvisation. A reliable communication structure is just as critical as firewalls and endpoint monitoring.
Specific assets that should be prepared in advance include:
- Pre-written templates for social media posts, email blasts, press releases, and recorded phone messages.
- Designated spokespersons trained in crisis communication to address press inquiries and public updates.
- A clear escalation plan that outlines what information should be shared at each phase of an incident.
- Emergency contact distribution lists for residents, local businesses, media, and relevant stakeholders.
Visibility must also extend past the moment of crisis. Regular communication drills, public briefings, and transparent governance create a climate of trust before threats ever surface.
Lesson #5: Partnering with Experts Can Accelerate Recovery
Abilene understood the limits of its internal capacity and acted without hesitation. As soon as the breach was discovered, the city engaged third-party cybersecurity firms and notified federal authorities.
That decision shortened the incident’s timeline, reduced uncertainty, and allowed technical experts to conduct forensic analysis with precision.
Many municipal IT departments are staffed by capable professionals, but the pace at which cyber threats evolve makes it unrealistic to expect internal teams to handle everything.
Attackers use advanced tools, custom malware, and tactics that shift frequently. Public-sector environments often lack the time, funding, and specialization needed to track these threats independently.
Establishing relationships with cybersecurity vendors in advance avoids delays. Waiting to draft contracts or gain approval during a crisis adds layers of confusion and unnecessary risk. When systems are down, recovery must begin immediately—not after paperwork is finalized.
To prepare effectively, municipalities should:
- Pre-negotiate contracts with vetted cybersecurity firms that can be activated instantly.
- Define clear authority for IT leads to engage external help without red tape.
- Work with legal teams ahead of time to approve emergency response procedures.
Include vendor partners in training exercises and simulations to ensure seamless collaboration.
Summary
Cybersecurity must become part of the essential infrastructure conversation for Texas municipalities. Roads, utilities, and emergency services already hold that status. Digital defense should join them.
Regional collaboration, shared threat intelligence, and joint training can strengthen defenses across city lines. Lone efforts won’t keep up with adversaries who operate globally and move fast.
