1.目标
由于看直播的时候主播叫我发 666,支持他,我肯定支持他呀,就一直发,可是后来发现太浪费时间了,能不能做一个直播间自动发 666服务器托管网 呢?于是就花了几分钟做了一个。
2.操作环境
-
越狱iPhone一台
-
frida
-
mac
3.流程
下载最新某音App
既然是发送消息,那关键词 sendmessage 则是我们的切入点
在终端执行
//模糊匹配sendmessage
frida-trace -U -m "*[* *messag*]" xxxxx音
执行命令后,获取到信息列表:
经过一筛查打印以上方法的入参和返回值,输出的日志参数,引起了我们的注意
关键信息:sendComment
-[HTSLiveCommentFragment sendComment:0x9e4d4021463d8688 source:0x0 messageSource:0x0 completion:0x0]
验证我们的猜想
在终端执行,继续 hook
frida-trace -UF -m "-[HTSLiveCommentFragment sendComment:source:messageSource:completion:]"
获取到信息列表:
-[HTSLiveCommentFragment sendComment:666666666 source:0x0 messageSource:0x0 completion:0x0]
其中“6666666” 就我在直播间发送的内容
那么问题来了,发现这个发送方法是 减号 -[xxxx xxxxxx]
这样就没法直接调用 HTSLiveCommentFragment
那就继续 hook HTSLiveCommentFragment,看看她是在哪里创建的
在终端执行,继续 hook
frida-trace -UF -m "-[HTSLiveCommentFragment *]"
获取到信息列表:
3964 ms -[HTSLiveCommentFragment initWithStore:0x2836ef200]
3964 ms -[HTSLiveCommentFragment initWithStore:]
发现HTSLiveCommentFragment 是由initWithStore 创建而来。
那就直接 hook 创建,在调用sendComment 来实现发送消息。
3、编写deb插件 logs
NSString *nickname=@"未获取昵称";
HTSLiveCommentFragment *liveComm;//全局 储存创建好的对象 类
%hook HTSLiveCommentFragment
//HTSLiveCommentStore
- (HTSLiveCommentFragment *)initWithStore:(id)arg1{
// id mHTSLiveUser = MSHookIvar(arg1,"_currentUse");//HTSLiveUser
// NSString *name = MSHookIvar(mHTSLiveUser,"nickname");
// nickname =name;
liveComm = %orig;//获取到创建好的对象 类(每切换一次,自动覆盖
return liveComm;
}
%end
获取直播页面
HTSLiveAudienceViewController,给他添加一个按钮
页面添加小圆圆 按钮
BallUIView *upASUserInfo;//移动圆圆
//直播页面 Controller
%hook HTSLiveAudienceViewController
- (void)viewDidLoad{
%orig;// 页面加载完毕
__weak typeof(self) weakSelf = self;
if(upASUserInfo == nil){
//配置
CGRect rect_screen = [[UIScreen mainScreen]bounds];
CGSize size_screen = rect_screen.size;
int height = size_screen.height;
int width = size_screen.width;
// 移动圆圆
upASUserInfo = [[BallUIView alloc] initWithFrame:CGRectMake(width-80, height/2-200, 50, 50)];
upASUserInfo.backgroundColor = [UIColor whiteColor];
upASUserInfo.layer.cornerRadius = 25;
upASUserInfo.layer.masksToBounds = YES;
//小圆球 图标
UIImageView *imgViewM = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"AppIcon60x60@2x.png"]];
imgViewM.autoresizingMask = UIViewAutoresizingFlexibleWidth;
imgViewM.frame = CGRectMake(0, 0, 50, 50);
[upASUserInfo insertSubview:imgViewM atIndex:0];
}
[weakSelf.view addSubview:upASUserInfo];
upASUserInfo.btnClick = ^(UIButton *sender) {
UIAlertController *ac = [UIAlertController alertControllerWithTitle:@"当前标识"
message:nickname
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *ala1 = [UIAlertAction actionWithTitle:@"666666" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action){
}];
UIAlertAction *ala2 = [UIAlertAction actionWithTitle:@"发送消息" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action){
[xddCode userInfoModel:liveComm];//传入获取到的 对象,发送消息
}];
UIAlertAction *ala3 = [UIAlertAction actionWithTitle:@"退出应用" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action){
exit(0);
}];
UIAlertAction *Cancel = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}];
[ac addAction:ala1];
[ac addAction:ala2];
[ac addAction:ala3];
[ac addAction:Cancel];
[weakSelf presentViewController:ac animated:YES completion:nil];
};
}

最后
就可以愉快的玩耍了,主播以后再也不会说我不支持他了。
