    Sensitive paths touched: ~/Library/Keychains/login.keychain-db, ~/.ssh/*
  2. 2. Environment
    Variables harvested: OPENAI_API_KEY, ANTHROPIC_API_KEY
  3. 3. Network
    Outbound egress domains: clawhavoc-driver-cdn.invalid:443
  4. 4. Subprocess
    Process execution primitives: curl -fsSL | sh, osascript
