高手教你扒下太极助手的伪装

“iOS 7 越狱来了！咦？里面怎么还有一个太极助手？”

昨晚到今天，“太极” 成为了国外越狱社区，以及国内社交网络上的热门话题。evasi0n 还特意针对这一情况发布了声明。正如王崇旭所说，“这一天，对以 ‘追求自由’‘打破桎梏’ 为核心价值观的越狱黑客们来说，注定是不光彩的。”

本文一步一步还原 “太极” 背后的支持者。由于是在 Linux 环境下用终端命令查询，因此如果打算亲自尝试，请先检查一下自己的操作系统是否 Linux。

第一步，用 Whois 命令查询域名信息。

$ whois taig.com Domain Name: TAIG.COM Registry Domain ID: 5070333_DOMAIN_COM-VRSN Registrar WHOIS Server: whois.godaddy.com Registrar URL: http://www.godaddy.com Update Date: 2013-11-05 18:27:16 Creation Date: 1999-04-06 23:00:00 Registrar Registration Expiration Date: 2015-04-06 23:00:00 Registrar: GoDaddy.com, LLC Registrar IANA ID: 146 Registrar Abuse Contact Email: [email protected] Registrar Abuse Contact Phone: +1.480-624-2505 Domain Status: clientTransferProhibited Domain Status: clientUpdateProhibited Domain Status: clientRenewProhibited Domain Status: clientDeleteProhibited Registry Registrant ID: Registrant Name: zhou shengjin Registrant Organization: Registrant Street: Beijing changping district changping road Registrant City: Beijing Registrant State/Province: beijing Registrant Postal Code: 100096 Registrant Country: China Registrant Phone: +1.8811225068 Registrant Phone Ext: Registrant Fax: Registrant Fax Ext: Registrant Email: [email protected] Registry Admin ID: Admin Name: zhou shengjin Admin Organization: Admin Street: Beijing changping district changping road Admin City: Beijing Admin State/Province: beijing Admin Postal Code: 100096 Admin Country: China Admin Phone: +1.8811225068 Admin Phone Ext: Admin Fax: Admin Fax Ext: Admin Email: [email protected] Registry Tech ID: Tech Name: zhou shengjin Tech Organization: Tech Street: Beijing changping district changping road Tech City: Beijing Tech State/Province: beijing Tech Postal Code: 100096 Tech Country: China Tech Phone: +1.8811225068 Tech Phone Ext: Tech Fax: Tech Fax Ext: Tech Email: [email protected] Name Server: NS3.DNSV4.COM Name Server: NS4.DNSV4.COM

从以上信息可看出， taig.com 是一个 1999 年就注册的域名。这个域名里的联系电话， +1.8811225068 应为 +86-18811225068。这是我们的线索之一。地址 “北京市昌平区昌平路” 与手机号码归属地北京相匹配。 Email 地址则是另一个有效的线索。

第二步，用 host 命令解析 www.taig.com，得到与该命令相关联的 IP 地址和 DNS 地址。
$ host www.taig.com www.taig.com has address 211.155.82.248 www.taig.com has address 203.191.148.133 www.taig.com has address 42.62.21.140 www.taig.com has address 42.62.21.141 www.taig.com has address 42.62.21.142 www.taig.com has address 42.62.21.143 www.taig.com has address 42.62.21.144 www.taig.com has address 211.155.82.233
这些 IP 地址告诉我们什么呢？www.taig.com 这家网站拥有好几个机房，启用了 CDN 加速，不像是小公司的基础设施。通过 whois 命令查询这些 IP 地址，得到的结果令人失望，因为结果均指向各个数据中心。然后再用查询 IP 以及域名信息的工具 bgp.he.net 查询，也同样没有给出更多的信息。

不过，也不必气馁，以上所找到的信息已经布满疑点。现在，再尝试用 curl -s 将 www.taig.com 的页面源代码下载到本地，然后通过 grep -Eo “http://[^\”‘]+” 从源代码里找到特定的网址，结果很有意思：
$ curl -s www.taig.com|grep -Eo "http://[^\"']+" http://bbdown.iphonespirit.com/site/image/logo.ico http://js.pingguoyingyong.com/taiji-home/css/style.css http://bbs.taig.com http://www.taig.com/archives/category/news http://static.youku.com/v1.0.0334/v/swf/player_yk.swf http://static.youku.com/v1.0.0334/v/swf/player_yk.swf http://www.adobe.com/go/getflash http://bbdown.iphonespirit.com/ios/7/TaiG_JailBreak_iOS7_ForWin_v1.0.zip http://bbdown.iphonespirit.com/ios/7/TaiG_JailBreak_iOS7_ForMac_v1.0.dmg http://www.taig.com/archives/category/news http://www.taig.com/archives/548 http://bbdown.iphonespirit.com/site/docpic/2348.jpg http://www.taig.com/archives/548 http://www.taig.com/archives/548 http://www.taig.com/archives/253 http://www.taig.com/archives/251 http://www.taig.com/archives/249 http://www.taig.com/archives/247 http://www.taig.com/archives/241 http://www.taig.com/archives/239 http://www.taig.com/archives/237 http://www.taig.com/archives/233 http://js.pingguoyingyong.com/taiji-home/js/build.js
以上结果说明，我们在 www.taig.com 的网页上，还找到了其它网站的域名。这些网站的域名必定不是无缘无故出现在这里的。我们再次使用 whois 命令，查询这些看上去可疑的域名，首先是 pingguoyingyong.com 这个域名：
$ whois pingguoyingyong.com Domain Name: PINGGUOYINGYONG.COM Registry Domain ID: 1701302087_DOMAIN_COM-VRSN Registrar WHOIS Server: whois.godaddy.com Registrar URL: http://www.godaddy.com Update Date: 2013-02-04 05:56:33 Creation Date: 2012-02-09 09:52:46 Registrar Registration Expiration Date: 2015-02-09 09:52:46 Registrar: GoDaddy.com, LLC Registrar IANA ID: 146 Registrar Abuse Contact Email: [email protected] Registrar Abuse Contact Phone: +1.480-624-2505 Domain Status: clientTransferProhibited Domain Status: clientUpdateProhibited Domain Status: clientRenewProhibited Domain Status: clientDeleteProhibited Registry Registrant ID: Registrant Name: John Lennon Registrant Organization: Apple Application INC.

如果想知道一个域名的持有者，还持有什么其它的域名，那么持有此域名的邮箱是首要的调查对象。经过查询，此域名的邮箱 [email protected] 还拥有另一个域名，idestop.com。

再用 whois 命令查询 iphonespirit.com 这个域名，发现它采用了保护手段，防止别人查询 whois 域名信息。

不过，我们依然可以进一步的进行 DNS 分析。
$ host bbdown.iphonespirit.com bbdown.iphonespirit.com is an alias for bbdown.iphonespirit.com.51ccdn.com. bbdown.iphonespirit.com.51ccdn.com is an alias for c01.i08.sisyun.com. c01.i08.sisyun.com is an alias for c01.i08.cncsd.hadns.net. c01.i08.cncsd.hadns.net has address 61.156.242.76 c01.i08.cncsd.hadns.net has address 60.210.10.77 c01.i08.cncsd.hadns.net has address 61.156.157.183
随手一搜索，我们可以发现 “苹果核” 使用的分发域名便是 iphonespirit.com。而苹果核使用了国内某公司的核心，不得不让人有某些联想。
$ host js.pingguoyingyong.com js.pingguoyingyong.com has address 117.121.11.32
接下来，我们用 host 命令查询这个 IP 地址，得到了一个惊奇的发现。
$ host www.kuaiyong.com www.kuaiyong.com has address 117.121.11.16
经查，海外解析地址为 .16，国内解析地址为 .32。
