ob混淆

 

 

 

 

 

 jsfuck 比如說對於一些jsfuck你放在控制台輸出報錯的，你直接點擊報錯信息，就能看到jsfuck的源碼

 

 

 

可以看到這段代碼就是這個

 

 

 針對於如果jsfuck不報錯的

可以在最后的括號里隨便添加個字符串，讓它報錯

像這樣

 

 

 

或者用腳本

(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：這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 + " <<<<<<<<<<<<<<<<<<<")
})();

前面是固定的額，后面加上jsfuck就行了，這么操作

 

 

 

還有一些表情包加密

也是老樣子，放到控制台。不報錯的話，刪掉一個表情就行了

 我們復制表情

 

 點報錯信息。就出來了
