解题过程
点开题目,发现是一堆乱乱的东西,审查元素无果
搜了一下 javascript aaencode,发现是一个把js代码转成颜文字的编码
在浏览器中显示的乱乱的东西,是编码的问题
换成正常编码之后是这样的:
这里给出正常编码下的代码:

找到一个aadecode在线解码的,复制粘贴进去,显示:
拿到console里跑一下,同样也报错:
点进去查看具体位置:
看不懂,去找aaencode的具体编码规则,发现在aaencode官网demo的源代码里有aaencode的具体实现方式,代码如下:

下面是代码的简单分析过程:
从网页按钮被按下后,首先调用的是keyup()
函数
找到编码源代码中的keyup
函数,(在第144行),然后在第149行和第150行可以看到,编码的具体函数是aaencode
。
第22行发现变量r
刚好是待解码的code的前半部分。
从第60行和61行来看,似乎无论什么代码,经过加密后,都:
- 以
゚ω゚ノ= /`m´)ノ ~┻━┻ //*´∇`*/ ['_']; o=(゚ー゚) =_=3; c=(゚Θ゚) =(゚ー゚)-(゚ー゚);
开头 - 以
(゚Д゚)[゚o゚]) (゚Θ゚)) ('_');
结尾
24到27行,还有日语,窝日语就会那么几句,看不懂
那搜一下在if
中出现的r += "X=_=3; ";
没有找到,说明编码过程中没有进入到
if
语句中,所以
if
语句不管,接着看下面。
对着编码源代码的第28~47行,把原题中的代码分开,结果:
(讲道理,现在窝已经不觉得颜文字可爱了= =)
然后把刚才报错的地方复制一小段:
在分开后的内容里查找一下(然后发现自己其实没必要分这么多= =):
对照编码源代码第29行,发现:
仔细看,发现题目给出的代码中少了一个小圈。
补全,得:

拿到console里跑,得到结果:
nctf{javascript aaencode}
提交,发现不对,拿到aadecode在线解码的网站,解码后,得到结果:
所以最后的flag为nctf{javascript_aaencode}
