Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (80%), with evidence including ransomware written in Golang and Rust (Qilin), and avoids dark web advertising (Play ransomware), Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), with evidence including deleting backups (Lynx ransomware), and disabling security tools likely, and Indicator Removal (T1070) with moderate confidence (60%), with evidence including rebranding of groups (e.g., Lynx, RansomHub), and loose structure of Scattered Lapsus$ Hunters. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), with evidence including stolen VPN credentials used, and potential brute force for credential access and Credentials from Password Stores (T1555) with moderate to high confidence (70%), with evidence including initial access brokers supply credentials, and help desk compromise (Scattered Lapsus$ Hunters). Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (80%), with evidence including data exfiltration before encryption, and targeting of high-value industries and System Information Discovery (T1082) with moderate to high confidence (70%), with evidence including targeting of Windows, Linux, VMware ESXi servers, and adaptation to victim environments. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), with evidence including data exfiltration before encryption (double extortion), and corporate data and PII compromised and Data from Information Repositories (T1213) with moderate to high confidence (70%), with evidence including targeting of critical infrastructure sectors, and high-value data stolen. Under the Command and Control tactic, the analysis identified Application Layer Protocol (T1071) with moderate to high confidence (80%), with evidence including raaS operations require C2 infrastructure, and affiliates communicate with operators and Ingress Tool Transfer (T1105) with moderate to high confidence (70%), with evidence including ransomware deployment via C2 channels, and tools transferred for encryption. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), with evidence including data exfiltration before encryption (double extortion), and high-volume data theft (e.g., Toyota, FedEx, Disney) and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), with evidence including data leaked on dark web or public sites, and salesforce campaign (Scattered Lapsus$ Hunters). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), with evidence including ransomware strains (.lynx, LockBit, etc.) encrypt files, and data encryption confirmed in incident, Data Destruction (T1485) with moderate to high confidence (80%), with evidence including deleting backups (Lynx ransomware), and potential destruction of recovery options, and Inhibit System Recovery (T1490) with moderate to high confidence (80%), with evidence including backup deletion (Lynx), and encryption of VMware ESXi servers (Qilin). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
