Managed Detection and Response Case Study for Healthcare

This case study outlines a U.S.-based healthcare organization's experience with a business email compromise (BEC) incident involving its shared human resources account. The threat actors gained access due to weak user credentials, leading to attempts to access organizational files and send emails to internal addresses. The organization, as a Pondurance Managed Detection and Response (MDR) customer, benefited from 24/7 monitoring by the Security Operations Center (SOC). The SOC detected the initial access through real-time log analysis and promptly reported the suspicious activity to the client's security team. The case study details the steps taken to track the threat actor within the Office 365 environment, validate file access, and activate the Incident Response (IR) team. Recommendations include continuous monitoring, having an IR plan, conducting security assessments, and enabling multi-factor authentication to enhance security posture.
