ob混淆
jsfuck 比如说对于一些jsfuck你放在控制台输出报错的,你直接点击报错信息,就能看到jsfuck的源码
可以看到这段代码就是这个
针对于如果jsfuck不报错的
可以在最后的括号里随便添加个字符串,让它报错
像这样
或者用脚本
(function() {
if (window.cr_eval) return
window.cr_eval = window.eval
var myeval = function (src) {
console.log("================ eval begin: length=" + src.length + ",caller=" + (myeval.caller && myeval.caller.name) + "===============")
console.log(src);
console.log("================ eval end ================")
return window.cr_eval(src)
}
var _myeval = myeval.bind(null) // 注意:这句和下一句就是小花招本招了!
_myeval.toString = window.cr_eval.toString
Object.defineProperty(window, 'eval', { value: _myeval })
console.log(">>>>>>>>>>>>>> eval injected: " + document.location + " <<<<<<<<<<<<<<<<<<<")
})();

前面是固定的额,后面加上jsfuck就行了,这么操作
还有一些表情包加密
也是老样子,放到控制台。不报错的话,删掉一个表情就行了
http://www.python-spider.com/challenge/16
我们复制表情
点报错信息。就出来了
