구글링하니 아래와 같은 소스가 제일 비슷하게 접근하는 듯 하네요.

<script>
!function() {
    function detectDevTool(allow) {
      if(isNaN(+allow)) allow = 100;
    var start = +new Date();
    debugger;
    var end = +new Date();
    if(isNaN(start) || isNaN(end) || end - start > allow) {
        alert('DEVTOOLS detected. all operations will be terminated.');
      document.write('DEVTOOLS detected.');
    }
  }
  if(window.attachEvent) {
      if (document.readyState === "complete" || document.readyState === "interactive") {
        detectDevTool();
      window.attachEvent('onresize', detectDevTool);
      window.attachEvent('onmousemove', detectDevTool);
      window.attachEvent('onfocus', detectDevTool);
      window.attachEvent('onblur', detectDevTool);
    } else {
        setTimeout(argument.callee, 0);
    }
  } else {
      window.addEventListener('load', detectDevTool);
    window.addEventListener('resize', detectDevTool);
    window.addEventListener('mousemove', detectDevTool);
    window.addEventListener('focus', detectDevTool);
    window.addEventListener('blur', detectDevTool);
  }
}();
</script>
