探寻
使用「穿梭」在搜索引擎中搜索，顺利的找到该应用的 Google Play 页面与 iOS APP Store 页面。
Google Play 页面
APP Store 页面
首先吸引我注意的是该应用超长的寿命。
通过 iOS APP Store 页面的 Version History，可以看到，该应用于2021年8月就已经上架 iOS APP Store，距今已有近3年时间了。
对于跑路不断的机场而言，稳定经营3年已经算是很长寿了。
然后便是Google Play 页面右侧 App Support Address 栏的那个中国地址：Tianfu Avenue 866, Huayang Street, Hi-Tech Zone, Cheng Du, Sichuan,China。
以及公司名 Chengdu Fobwifi Networks Technology LLC 中的 Chengdu。
在 Google Play 页面与 iOS APP Store 页面分别找到了两个官网地址： https://www.transocks.com/、https://transocks.org/ 。
打开后，页面一致。其中 www.transocks.com 已被 GFW 屏蔽，屏蔽方式 DNS 投毒。
官网网页
附手查询两域名 wohis，可以发现 transocks.com 注册于2014年8月，transocks.org 注册于2019年7月。
