Use Case 2: EDR Mitigation and Rollback of a Ransomware Incident

Overview

Cybervergent is a comprehensive solution designed to enhance security, compliance, risk, and privacy management for organizations.

With both on-premises and cloud capabilities, it seamlessly integrates with third-party APIs, platforms, and systems.

Cybervergent helps with data protection and governance to ensure that organizations meet global regulations while maintaining operational efficiency.

The Challenge

A leading insurance firm suffered a sophisticated ransomware attack that bypassed legacy security controls via a vulnerable administrative endpoint. The payload rapidly encrypted files containing vital information, including the central claims processing database and thousands of records of policyholder Personally Identifiable Information (PII) stored across local and regional systems.

Insurance firms handle vast amounts of highly sensitive financial and personal data, making them prime targets. They must comply with stringent data protection laws (like NDPA and GDPR) and ensure uninterrupted service delivery, as any disruption in claims processing can cause immense financial and reputational damage.

The attack instantly halted the firm’s ability to process new claims and issue payouts, resulting in massive customer service disruption. Furthermore, the encryption of PII posed a direct and severe risk of a major data breach, leading to potential multi-million dollar regulatory fines and loss of customer trust.

The Solution

Immediate Threat Containment: The EDR system detected the ransomware's execution behaviour and automatically isolated infected endpoints from the network, preventing further lateral spread and securing the claims PII database.

Rapid System Rollback: Leveraging the EDR's rollback capability, the security team initiated a rapid restoration process to revert affected claims systems to a pre-infected, known-good state, ensuring continuity of customer services.

Actionable Threat Intelligence: The EDR system provided real-time visibility into the ransomware's entry point, behaviour, and lateral movement, aiding forensic analysis and enabling security teams to patch vulnerabilities immediately.

Proactive Vulnerability Management: This process facilitated the identification of the initial attack vector, allowing the firm to strengthen defences against similar future threats through robust patch management and stricter access controls.

The Results

The insurance firm avoided a catastrophe thanks to Cybervergent's EDR solution. The EDR's ability to automatically isolate and roll back the affected systems ensured that the core claims and policy administration systems were restored in less than 4 hours, achieving minimal service interruption. The insurer successfully maintained full operational continuity during a critical period, secured zero data loss (as the data was rolled back, not exposed), and was able to provide clear, immediate documentation to regulators, preventing a potential NDPA/GDPR violation and reinforcing policyholder trust.
