Under the Execution tactic, the analysis identified User Execution (T1204) with moderate to high confidence (80%), with evidence including phishing remains a primary infection vector, and aI-driven attacks enhance social engineering lures and Command and Scripting Interpreter (T1059) with moderate to high confidence (70%), supported by evidence indicating ransomware-as-a-Service (RaaS) – Pre-built ransomware tools and infrastructure. Under the Persistence tactic, the analysis identified BITS Jobs (T1197) with moderate confidence (60%), supported by evidence indicating ransomware strains like LockBit 5.0 use advanced persistence mechanisms and Boot or Logon Autostart Execution (T1547) with moderate confidence (60%), supported by evidence indicating ransomware strains often establish persistence via autostart. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating exploiting Unpatched Systems – Known flaws in outdated software and Abuse Elevation Control Mechanism (T1548) with moderate confidence (60%), supported by evidence indicating ransomware often abuses elevation mechanisms for privilege escalation. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (80%), supported by evidence indicating ransomware strains like LockBit 5.0 use private negotiation portals, Impair Defenses (T1562) with moderate to high confidence (70%), supported by evidence indicating ransomware often disables security tools to evade detection, and Indicator Removal (T1070) with moderate to high confidence (70%), supported by evidence indicating 85% of attacks go unreported (BlackFog). Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating ransomware groups often use brute force to access credentials and Credentials from Password Stores (T1555) with moderate to high confidence (70%), supported by evidence indicating phishing and AI-driven attacks target password stores. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating ransomware groups perform account discovery for lateral movement and File and Directory Discovery (T1083) with moderate to high confidence (80%), supported by evidence indicating data exfiltration and encryption require file discovery. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (70%), supported by evidence indicating supply chain attacks enable lateral movement across downstream victims and Remote Services (T1021) with moderate to high confidence (70%), supported by evidence indicating ransomware spreads via remote services in unpatched systems. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), with evidence including 62M students and 9.5M teachers data compromised (PowerSchool), and 193M victims (Change Healthcare) and Data from Network Shared Drive (T1039) with moderate to high confidence (80%), supported by evidence indicating ransomware groups exfiltrate data from shared drives. Under the Command and Control tactic, the analysis identified Application Layer Protocol (T1071) with moderate to high confidence (80%), supported by evidence indicating ransomware groups use C2 channels for data exfiltration and encryption and Ingress Tool Transfer (T1105) with moderate to high confidence (70%), supported by evidence indicating raaS tools and infrastructure require tool transfer. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), with evidence including 1TB of data stolen (NASCAR), and data exfiltration confirmed in multiple incidents and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating ransomware groups use web services for data exfiltration. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), with evidence including ransomware strains encrypt data for extortion, and data encryption confirmed in multiple incidents, Service Stop (T1489) with moderate to high confidence (80%), with evidence including disrupted loan services (LoanDepot), and service disruptions and revenue losses (Ingram Micro), Defacement (T1491) with moderate confidence (50%), supported by evidence indicating ransomware groups may deface systems as part of extortion, and Inhibit System Recovery (T1490) with moderate to high confidence (70%), supported by evidence indicating ransomware often disables recovery mechanisms. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
