我已经注意到我的一些系统应用程序中的不寻常和不需要的行为,最常见的谷歌播放服务,谷歌客户经理和Google服务框架。这些应用程序导致力量关闭自己的运营以及其他应用程序,它们似乎有能力在时代完全接管手机的功能。

所以,我使用了virustotal.com工具来分析这些应用程序的权限,以确定它们是否存在于手机上预安装的版本中内置的正确功能。对于每个应用程序,他们在10-20之间返回,每个权限都没有设计,这表明他们已经被篡改了。

我的手机没有以任何方式植根或修改,我已经不到一年了。这些附加权限标记为:

(来自Android参考的未知权限)

将这些特定权限指定为原产于这些应用程序。其中一些权限专门设计用于通过C2DM和GTANK传输和通信,以及GTANK到其他设备,以及保存的帐户详细信息包括密码。这让我得出结论,敏感的个人信息已被泄露给第三方。以下是Google Container Manager的输出,例如示例:

  /dev/block/mmcblk0p23  

我应该把这些信息带到注意力吗?这几乎确定了我的手机是否完全受到损害?

I have noticed unusual and unwanted behavior from a few of my system apps, most notably Google Play Services, Google Account Manager, and Google Services Framework. These apps cause force closes on their own operations as well as those of other apps, they seem to have the capability to take over functionality of my phone completely at times.

So, I used the Virustotal.com tool to analyze permissions on these apps to determine if they are present with the right capabilities built into them for the version that came pre-installed on the phone. For each of these apps, they returned between 10-20 additional permissions each that they were not designed to have, suggesting that they have been tampered with.

My phone is not rooted or modified in any way and I have had it for less than a year. These additional permissions were labeled:

(Unknown permission from android reference)

designating these specific permissions as not being native to these apps. Some of these permissions are specifically designed for transmission and communication of data via C2DM and Gtalk to other devices, as well as exposure of saved account details including passwords. This leads me to conclude that sensitive personal information has been leaked to third parties. Here is the output for Google Account Manager as an example:

Who should I bring this information to the attention to? Is it pretty much certain that my phone is completely compromised?

虽然我同意您的Google应用程序兼容性有问题,但我认为这些应用程序不会受到损害。

Android SDK(软件开发套件)提供了在上列出的一些标准权限它的官方文档(和有关android.se的一些详细信息< / a>)。

否则,Android允许他们的开发人员声明新权限其他应用程序使用。可以看出,Google与GTalk示例一样( com.google.android.gtalkservice.permission.GTALK_SERVICE )。它对于应用程序(来自同一开发人员)的应用程序正常使用来使用自定义许可。

现在,毒蚀地标记为"未知权限" 的原因,因为我相信,它只检查标准权限,这是合理的,因为没有引用所有由其他人定义的自定义权限应用。 (Virustotal可能与谷歌或其他可信公司一起工作,将其自定义权限存储为"已知" ,但它在上下文之外)。

所以结论是"未知权限" 并不意味着应用程序被篡改/妥协。它只是Android SDK的标准权限。实际上,许多其他应用程序还使用相同的权限来使用Google提供的服务,例如C2DM(或GCM,Google云消息传递),GMAPE等,这不是标准的Android权限(和组件)。

 

While I agree that there's something wrong with your Google apps compatibility, I don't think those apps are compromised.

Android SDK (Software Development Kit) provides some standard permissions that are listed on its official documentation (and some of the details on Android.SE).

In addition of that, Android allows their developer to declare new permissions to be used by other apps. As it can be seen, Google does that with example of Gtalk (com.google.android.gtalkservice.permission.GTALK_SERVICE). It's normal for an app (even more, from the same developer) to use the custom permission for their needs.

Now, the reason why VirusTotal labels them as "unknown permission" because, I believe, it only checks for standard permissions, which is reasonable since there are no references for all custom permissions defined by other apps. (VirusTotal could probably work together with Google or other trusted companies to store their custom permissions as "known", but it's outside of the context).

So the conclusion is, "unknown permission" doesn't mean the app is tampered/compromised. It's just not a standard permission from Android SDK. In fact, many other apps also use the same permissions to use Google provided services, such as C2DM (or GCM, Google Cloud Messaging), GMaps, etc, which are not a standard Android permissions (and components).
