CISA: Ransomware Attack Disrupts Trimble Cityworks, Threatening Local Governments

In late February 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a critical alert regarding a ransomware attack targeting Trimble Cityworks, an asset management platform widely used by local governments and infrastructure organizations across the United States. The attack, detailed in a report by Cyber Security Hub, exploits vulnerabilities in Cityworks’ systems, enabling attackers to encrypt critical data and disrupt municipal operations. This incident, discovered in early 2025, has raised concerns about the security of software integral to managing public infrastructure, from utilities to public works.
