Abstract
This report applies the structured analytic technique of Analysis of Competing Hypotheses (ACH) to
systematically evaluate the nature of relationships between cybercriminal organizations perpetrating
ransomware attacks against healthcare entities. The analysis focuses specifically on whether ransomware
groups targeting healthcare demonstrate patterns of rivalry, collaboration, or some combination of both.
Understanding these relationships has significant implications for threat intelligence, defensive strategies,
and policy responses. The healthcare sector's unique characteristics - including its distributed nature,
reliance on legacy systems, and the life-critical nature of its services - make it particularly susceptible to
coordinated attacks, while also potentially creating competitive dynamics among threat actors seeking to
exploit these vulnerabilities. Three primary ransomware groups have dominated attacks against healthcare
organizations in recent years:
Conti
REvil (Sodinokibi)
LockBit.

Analysis of Competing Hypotheses: Ransomware Attack Trends in Healthcare
Introduction
The healthcare sector has emerged as one of the most vulnerable and frequently targeted
industries by cybercriminal organizations, with ransomware attacks representing the predominant threat
vector. This targeting stems from healthcare's critical nature, time-sensitive operations, and the high value
of patient data, which creates strong incentives for organizations to pay ransoms (Kruse et al., 2017). The
sector has witnessed an alarming escalation in both the frequency and sophistication of ransomware
attacks, with threat actors continuously evolving their tactics, techniques, and procedures (TTPs) to
maximize impact and financial gain.
