The Ransomware Blueprint: Attack Patterns and Strategic Variations Across Gangs
Abstract
In recent years, ransomware has become one of the most disruptive and adaptive cyber threat categories, raising significant challenges for both researchers and practitioners in identifying effective defensive strategies.
This study provides a large-scale analysis of ransomware attacks and associated adversarial behaviors from 2020 to 2024, leveraging a dataset of more than 16,000 documented ransomware incidents involving 155 distinct gangs.
The analysis identifies exploited software vulnerabilities (CVEs) and maps them to adversarial behaviors within the MITRE ATT&CK framework. In addition to this technical mapping, the study distinguishes between generalist gangs, characterized by broad targeting across multiple industries, and specialist gangs, which tend to focus on narrower sectors and more selective victim profiles.
The research reconstructs a recurring operational model — referred to as the “ransomware blueprint” — highlighting common attack patterns spanning initial access, privilege escalation, lateral movement, and impact.
Key findings include:
- Frequent exploitation of high-severity and widely deployed vulnerabilities, particularly in public-facing applications
- Recurring use of privilege escalation, lateral movement, and encryption-related impact techniques
- Differences in operational emphasis across groups, sectors, and geographic contexts
- A contrast between highly adaptable, multi-sector ransomware actors and more focused, lower-complexity operators
The study also examines the overlap of techniques across gangs in order to assess the degree of behavioral similarity and interconnection within the ransomware ecosystem.
Overall, these findings provide actionable intelligence for defenders and support the development of more targeted approaches to vulnerability management, detection engineering, and sector-specific hardening strategies.
