Espionage Track

• Primary Goal: Gathering intelligence on military and diplomatic targets.
• Operators: Lazarus Group
• Tools:

• Operators: Andariel
• Tools:
  • Rapid deployment of destructive malware once access is gained, spreading laterally before defenders can react.
  • Timing attacks to coincide with political or military events for maximum impact.
