Sedgwick, a leading global claims management and risk services provider operating in the insurance and risk solutions sector, has confirmed a cybersecurity incident at its federal contractor unit. The incident was disclosed on January 5, 2026, after the TridentLocker ransomware group claimed to have stolen 3.4GB of data from Sedgwick Government Solutions, a subsidiary of the company.
Sedgwick Government Solutions is responsible for handling claims and risk management for U.S. federal agencies, including the Department of Homeland Security (DHS), Immigration and Customs Enforcement (ICE), the U.S. Citizenship and Immigration Services (USCIS), the Department of Labor (DOL), and the Cybersecurity and Infrastructure Security Agency (CISA). The company's operations are segmented from those of its parent company, Sedgwick, to prevent any potential impact on broader systems or data.
The TridentLocker ransomware group is a relatively new operation that emerged in late November 2025. The group uses standard double-extortion tactics, encrypting systems and threatening to release exfiltrated data if ransoms are not paid. TridentLocker primarily targets North America and Europe, as well as China and the United Kingdom.
According to Sedgwick, no evidence of access to claims management servers or any impact on the subsidiary's ability to continue serving clients has been found. The company notified law enforcement and is notifying impacted customers, emphasizing that there was no wider Sedgwick systems or data affected by the incident.
The Tor leak site lists 12 confirmed victims since the beginning of the TridentLocker operation in November 2025. This incident serves as a reminder of the ongoing threat posed by ransomware-as-a-service (RaaS) groups and the importance of robust cybersecurity measures for organizations handling sensitive government data.
Sedgwick's response to the incident is noteworthy, with the company immediately activating its incident response protocols and engaging external cybersecurity experts through outside counsel. This proactive approach suggests that Sedgwick is committed to minimizing the impact of the breach and ensuring the security of its operations.
In recent months, several high-profile ransomware attacks have highlighted the growing threat posed by these groups. The attack on Sedgwick Government Solutions serves as a reminder for organizations handling sensitive data to prioritize cybersecurity measures and stay vigilant against emerging threats.
Furthermore, this incident raises questions about the effectiveness of law enforcement agencies in responding to cyber threats. While Sedgwick has notified law enforcement, it is unclear whether there have been any successful investigations or takedowns of TridentLocker operatives. The lack of information on this front underscores the need for continued cooperation between law enforcement and private sector organizations to combat these threats.
In conclusion, the data breach disclosed by Sedgwick Government Solutions provides a glimpse into the ongoing threat landscape posed by ransomware-as-a-service groups. As organizations handle sensitive government data, it is crucial that they prioritize robust cybersecurity measures and stay vigilant against emerging threats.
The incident also highlights the importance of effective communication and notification protocols in the event of a breach. Sedgwick's prompt disclosure of the incident and its response to the threat demonstrate a commitment to transparency and minimizing the impact on affected customers.
Ultimately, this incident serves as a reminder for organizations to review their cybersecurity posture and ensure that they are taking proactive steps to protect against emerging threats. By prioritizing cybersecurity measures and staying informed about emerging threats, organizations can reduce their vulnerability to ransomware attacks like the one suffered by Sedgwick Government Solutions.
