Rhysida Ransomware Group Targets Community Care Alliance in Devastating Cyberattack
Overview of Community Care Alliance
Community Care Alliance (CCA), based in Woonsocket, Rhode Island, is a non-profit organization dedicated to improving the lives of individuals and families facing various challenges. With a mission to address the social, economic, and emotional needs of the community, CCA offers over 50 programs and services, including mental health and addiction treatment, housing assistance, education and employment support, and basic needs assistance. The organization operates as a 501(c)(3) public charity and employs a significant workforce across multiple locations in northern Rhode Island.
Details of the Ransomware Attack
On July 29, 2024, Community Care Alliance fell victim to a ransomware attack orchestrated by the Rhysida Ransomware Group. The attack has raised significant concerns due to the sensitive nature of the services provided by CCA. While the exact size of the data leak remains unknown, the breach has potential implications for the privacy of CCA's clients and the organization's operations. The attackers have claimed responsibility on their dark web leak site, further exacerbating the situation.
About the Rhysida Ransomware Group
The Rhysida Ransomware Group emerged in May 2023 and has since targeted various sectors, including healthcare, education, manufacturing, information technology, and government. Rhysida ransomware is written in C++ and primarily targets Windows Operating Systems. The group employs a double extortion technique, stealing data before encrypting it and threatening to publish it on the dark web unless a ransom is paid. Rhysida uses the ChaCha20 encryption algorithm and generates ransom notes as PDF documents named “CriticalBreachDetected.pdf.”
Penetration and Vulnerabilities
Rhysida typically gains initial access through phishing campaigns and leveraging valid credentials. They establish network connections via VPN and use tools like Advance IP/Port Scanner to gather critical information about domains. For lateral movement, they deploy ransomware using Sysinternals tools like PsExec. The group's ability to exploit vulnerabilities in network security and leverage valid credentials makes organizations like CCA, which handle sensitive data, particularly vulnerable.
Impact on Community Care Alliance
The ransomware attack on Community Care Alliance has significant implications. Given the organization's role in providing comprehensive social services and mental health care, the breach could disrupt critical services and compromise the privacy of vulnerable individuals. The attack underscores the importance of robust cybersecurity measures, especially for organizations handling sensitive information.

Recent Ransomware Attacks
The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.
The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
