常见hook脚本

常见的hook脚本

过定时器setInterval

var _setInterval = setInterval
setInterval = function (a,b) {
    if(a.toString().indexOf('debugger') == -1){
        return function(){}
    }else{
        _setInterval(a,b)
    }
}

Function.prototype.toString = function () {
    return `function ${this.name}() { [native code] }`
}

定时器死循环

setInterval(() => {}, 500)

构造器hook

Function.prototype.constructor_old = Function.prototype.constructor;
Function.prototype.constructor = function (argument) {
  if (argument === 'debugger') {

  } else {
    return Function.prototype.constructor_old.apply(this, arguments)
  }
}

cookie hook

var cookieTemp = '';// 定义空字符串
  Object.defineProperty(document, 'cookie', {

    set: function (val) {
      // 设置 cookie的信息,检测到 cookie的值的信息
      if (val.indexOf('m') != -1) {
        debugger; // 设置断点
      }
      console.log('Hook捕获到cookie设置->', val);
      cookieTemp = val; //获取到cookie的信息;
      return val;
    },
    get: function () {
      return cookieTemp;// 返回 cookie的信息
    },
  });

console = new Object()
console.log = function (s) {
    while (1){
        for(i=0;i<1100000;i++){
        history.pushState(0,0,i)
            }
    }

}
console.toString = '[object Object]'
console.log.toString = 'ƒ toString() { [native code] }'
