Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (70%), supported by evidence indicating automation drove attack surge (2,201 weekly attacks) and Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating rust-based encryptor used by Qilin ransomware group. Under the Persistence tactic, the analysis identified External Remote Services (T1133) with moderate to high confidence (70%), supported by evidence indicating cloud environments targeted for persistence and Server Software Component (T1505) with moderate confidence (60%), supported by evidence indicating fortiGate devices exploited for backdoor access. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (80%), supported by evidence indicating cVE-2024-55591 exploited on FortiGate devices and Abuse Elevation Control Mechanism (T1548) with moderate confidence (60%), supported by evidence indicating cloud misconfigurations enabled privilege escalation. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with high confidence (90%), with evidence including rust-based encryptor used by Qilin, and surgical evasion techniques by The Gentlemen, Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating genAI tools fragmented adoption (governance gaps), and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating cloud environments targeted (likely valid accounts abused). Under the Credential Access tactic, the analysis identified Unsecured Credentials: Cloud Instance Metadata API (T1552.005) with moderate to high confidence (80%), with evidence including cloud vulnerabilities exploited, and genAI prompts contained sensitive info and Adversary-in-the-Middle (T1557) with moderate confidence (60%), supported by evidence indicating 1 in 28 GenAI prompts posed high risk of data leakage. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating high-value sectors targeted (Education, Government, Telecommunications) and Cloud Service Discovery (T1526) with moderate to high confidence (80%), supported by evidence indicating cloud environments and GenAI tools targeted. Under the Lateral Movement tactic, the analysis identified Remote Services: Cloud Services (T1021.007) with moderate to high confidence (80%), supported by evidence indicating cloud vulnerabilities enabled lateral movement and Lateral Tool Transfer (T1570) with moderate to high confidence (70%), supported by evidence indicating ransomware groups (Qilin, DragonForce) expanded RaaS infrastructure.
