猿人学第四题，雪碧图、样式干扰 两分钟后：里面用到了类似于字体加密，但是是把数字用base64转成了图片，但是有个规律就是每个数字都是固定的base64，然后就可以取到很多数字，然后有一个class用到了MD5和base64加密，最后删除包含这个class的img，就得到了四位数，但是四位数顺序是乱的，然后就需要根据style里面的margin去换位置，最终就可以将正确的数字取出来，如上图，然后再整一整就是下图了Python代码：import

JS逆向之MD5加密 这两天碰到了两个MD5加密的js逆向，一个是猿人学第一题，还有一个就是在工作中。然后发现了些规律，一般MD5加密之后的字符串是32位,也有16位，这基本都知道但是在MD5加密的js代码中也有一些规律。这是我昨天在猿人学里面获取到的MD5加密代码var hexcase = 0; var b64pad = ""; var chrsz = 16; function hex_md5(a) { return binl2hex(core_md5(str2binl(a), a.length * chrsz)) } function b64_md5(a) { return binl2b64(core_md5(str2binl(a), a.length * chrsz)) } function str_md5(a) { return binl2str(core_md5(str2binl(a), a.length * chrsz)) } function hex_hmac_md5(a, b) { return binl2hex(core_hmac_md5(a, b)) } function b64_hmac_md5(a, b) { return binl2b64(core_hmac_md5(a, b)) } function str_hmac_md5(a, b) { return binl2str(core_hmac_md5(a, b)) } function md5_vm_test() { return hex_md5("abc") == "900150983cd24fb0d6963f7d28e17f72" } function core_md5(p, k) { p[k >> 5] |= 128 << ((k) % 32);

JS逆向之跳过无限Debugger，搞定反调试之无限debugger 咳咳，今天上班的时候，有位大佬在钉钉群里发了一个链接，随后就撤回了，但还是被我看见了，便点进去看了一下然后回到首页，一看。哦吼，这不就激起我的好奇心了嘛。然后点进第一题。。。就开始了我的摸鱼之旅，搞了一上午总算把第一题弄出来了，只能说我还是太菜了。然后其中有一个无限Debugger，我最一开始是关掉了调试。然后找到了接口，看了一个参数m，不调试不行呀，然后我想到用Burpsuite在页面加载之前就把这两行引用代码干掉。发现不太行，页面一刷新他就又回来了，然后我想到反正只要不加载就行了，好像浏览器里面自带一个block request url右键这个js请求，然后block request url就可以了。搞定，但是好像此方法仅限于js中没有重要代码的。
