tiktok最新风控算法以及视频播放量问题研究
|
今天逛csdn，发现了一篇精髓文章 以下是传送门，特别声明： 转自： 一、抓包预准备 抓包对于绝大多数海外tt玩家是一件比较头疼的事。android的，网络通信协议绕不过去，好不容易xposed能搞定的绕过去了，发现手机参数搞不定，不展示大陆区内容，直接黑屏。ios的改改手机参数倒是能用，然鹅，新系统新版本一律不让抓包。 对此，笔者提供2个目前来看最完美的解决方案“思路”，android的so魔改和ios的升级策略，可以避开国区检测，也可以避开通讯协议检测。so魔改涉及的东西太多，包括jada逆向、ida反编译、adb操作。大致跟各位分享下过程： android：使用重编译的apk，加上修改的libsscronet.so，可完美避开检测和断网 ios：登录账号后，升级ipa的策略对于抓包来说，可直接通过缓存证书无视网络检测 二、抓包进行时 1、风控算法 （1）设备注册算法 跟国内某音的设备算法不一样。某音再某些接口对设备的要求极高，得正确加密register接口+点击确认接口+活动范库接口+日志或者监控接口+配置接口+激活策略之一，才能做一些比较高端的操作（播放、点赞、关注等，采集之类的接口可仅保留头尾策略即可），而tiktok相对简洁，只需要正确加密register接口+mac绑定+google频道绑定+激活策略之一即可，相比流程少了很多  {

'install_id': 7165350779095746309
}（2）加密算法 早期的加密算法只有x-gorgon和x-khronos两个核心参数，新版本加上了x-argus和x-ladon，并且在jadx里面通过关键字已经无法定位到算法入口了。对于绝大部分的接口，其实可以不需要这两个参数，比如feed、视频post、search等，但是user、stats、follow、digg之类的是需要新的加密参数的  {

} 2、风控策略 ok，说了那么多，我们开始研究播放量的问题，我们找了一个冷门的网红、一个冷门的视频来测试：Tiktok视频链接 （我也不知道这老哥是谁）  原始播放为206，手机打开这个视频，看了一会，发现播放量变成 207  抓包发现api为： https://api26-normal-hl.amemv.com/aweme/v1/aweme/stats/?开头 然后再次请求该api，发现播放量变成208  用设备去请求 {'device_id': 7165366997055489542, 'install_id': 7165368214708061957} {'X-Gorgon': '040460910000b4fe5e5c679b1a5aca8d0565b3de7aeac3798f6d', 'X-Khronos': '1668317354', 'X-Ladon': 'tLkHbGCrhmcvTPmlKHGkTta6Ti/YLihAsfKVgFEWFRiQV9YD', 'X-Argus': 'sCyeoOH45ibTP/CRUzAMJV1RJ337mffXnKw7lg4DOesS3htUSiUzUQy8i/csmSpKh/1ZqlycbmpLBsQEcHhXAY/jvNc6LkhmqBjn6xrYmSXrqL3JCb09o04fAaXQesxY2PBU3+JeBznMpjU1Gd7mRSEYEIXomcoH/CAyLAaoCcBGvB+DMH3xRm1TKLwj0/qorwsi6iO5x8w3t9MKpj1TX9raqMDo591OBvpEXG29XJR1gVd4bpgJeP6Ckc01p+2hfm8gpvKy1Y7MDeYXo6UDFQA0'} post参数 pre_item_playtime=&first_install_time=1598329642&item_id=7165147705835015461&follow_status=0&sync_origin=false&follower_status=0&hide_mix_entry=true&action_time= 1668317412&tab_type=0&pre_hot_sentence=&play_delta=1&aweme_type=0&pre_item_id=ok变成209  咱们新生成一个新的设备，联系请求100次，看下效果  掌声！！！！！ 三、总结 1、经测试，要想短时间大量上，需要高并发+高频率切换device_id，要想花费少量的device_id，需要低频请求 2、高并发可以短时间单个设备完成多则12W的量，少则几千 3、风控为两种：ip和设备。好的设备上量多，好的ip上量多 |
