    // 1. Create target object in Aura
    let target = document.createElement('div');
    // 2. Setup specific Aura properties
    document.body.appendChild(target);
    
    // 3. Trigger the vulnerability sequence

    // 4. Free the object
    document.body.removeChild(target);
    target = null;
    
    // 5. Reclaim memory with attacker controlled data
    let buffer = new ArrayBuffer(0x100);
    let view = new Uint8Array(buffer);
    for(let i=0; i<view.length; i++) view[i] = 0x41;
    
    // 6. Trigger Use-After-Free to achieve Sandbox Escape
