解析藏宝阁密文

发表于

以下内容仅作为技术讨论使用，务商业使用。

在查看梦幻藏宝阁的时，像了解下对于数据的展示，这种平台是如何操作，于是对网页数据进行了分析，以下是分析出数据的方法。

对于一些敏感数据，网站就需要对其进行混淆，增加爬虫的成本。

例如网页https://xyq.cbg.163.com/equip?s=212&eid=201908132100113-212-AQYRMWM0DU8U&o&equip_refer=58

分析其返回的response,发现返回值并没有直接赋值上去。

		<th>体质：</th>

	</tr>
	<tr>

	</tr>
	<tr>
		<th>攻击：</th>
		<td><%= pet.attack %></td>
		<th>力量：</th>

	</tr>

由pet对象来获取，则在网页中查找这个对象

<%
   var pet = this.pet_attrs;
   var enhance_info = this.enhance_info || {};
%>

继续查找pet_attrs

var pet_desc = parse_desc_info($("equip_desc_" + el.getAttribute("data_equipid")).value);
var pet_attrs = get_pet_attrs_info(pet_desc, true);

这串代码中，根据equip_desc_查到到了这个网页的主要信息内容。

</textarea>

过程有些顺利

接下来在解析角色时，发现equip_desc_value的value值并没有直接体现出来。
如：https://xyq.cbg.163.com/equip?s=579&eid=201907212200113-579-5ZF1WK0H3GFP&equip_refer=26&view_loc=reco_left

1
<textarea id="equip_desc_value" style="display:none"><textarea id="equip_desc_value" style="display:none">@VB38(因内容太多，此处省略)DAxOSJ9@</textarea>

继续追本溯源查找equip_desc_value，查找到以下代码

1
var role_info = js_eval(lpc_2_js(get_equip_desc('equip_desc_value')));

通过打断点的方式发现get_equip_desc方法为解析加密的内容的核心方法。（lpc_2_js是将字符串转为对象字符串的方法，并不是核心方法）
继续往下查找get_equip_desc方法

1
2
3
function get_equip_desc(elemId) {
    return decode_desc($(elemId).value);
}

好吧，继续查看decode_desc方法,看到这种代码，终于进入主题了。

对此先将方法去混淆.刚开始看到 _0x1c0cdf[_0x3a8e(‘0x1’)](0x0, _0x33c80e) 这种写法我还懵圈了老半天，这是种什么写法。后来在去混淆的过程中发现 _0x3a8e(‘0x1’) 的值是substring，这不就是方法名吗，然后意识到，这不就是js调用方法的另一种写法吗 ，只是很久不用这种写法第一眼没有认出来。
