Union County, Pennsylvania, recently experienced a cyberattack that compromised personal information, including Social Security and driver’s license numbers. The county first detected ransomware on its network on March 13, 2025, and immediately launched an investigation with the help of cybersecurity experts and federal law enforcement. The investigation revealed that cybercriminals had gained unauthorized access to sensitive data stored on the county’s network, affecting individuals involved with county law enforcement, court cases, and other county services.
The county’s officials are continuing to assess the extent of the breach, with a focus on identifying which individuals’ data may have been impacted. They confirmed that the stolen data included personally identifiable information but have yet to determine the full scope of the breach. In compliance with Pennsylvania law, Union County is notifying potentially affected individuals while the investigation is ongoing. Once the review of the compromised data is completed, the county will send written notices and offer free credit monitoring services to those affected by the breach.
In response to the attack, Union County has implemented several measures to enhance its cybersecurity defenses.
The county has deployed advanced security tools to improve detection and response to cyber incidents and is actively monitoring its network for any signs of further unauthorized access. Additionally, the county has conducted an enterprise-wide password reset and strengthened restrictions on external network access to prevent future incidents.
These efforts are aimed at securing county data and preventing the recurrence of such attacks.
To mitigate the risk for affected individuals, Union County recommends several preventive measures. Residents are advised to closely monitor their bank and credit card statements, as well as their free credit reports, for any signs of fraud. The county also encourages individuals to report suspected identity theft to local law enforcement, the state Attorney General, and major credit bureaus. As part of its commitment to protecting citizens’ information, Union County is also providing guidance on how to place security freezes on credit reports and offering additional resources for identity protection.
