    Hi @HuaweiMobile 👋! In the #HuaweiP8Lite, I found a system application made by Huawei called "imonitor". Among other things, this app is able to dump all the internet traffic of the user.pic.twitter.com/SLHgo55qJc

        To check if you have this app installed: 1) Open Settings 2) Apps 3) More -> Show system processes 4) Find imonitor in the listpic.twitter.com/bzhK1uYOuo

        After going through the setup wizard, I noticed the service LogCollectService which belong to imonitor. At each boot, this service is started and never killed. imonitor has dangerous permissions out of the box like: - ACCESS_FINE_LOCATION - READ_PHONE_STATE - SYSTEM_ALERT_WINDOWpic.twitter.com/JscmUUAGnL

        In AndroidManifest.xml, the LogBroadcastReceiver is listening to an action called "com.huawei.lcagent.TCPDUMP". It's worth to say that this receiver is protected by a signatureOrSystem permission. So only a @HuaweiMobile app or a system app can send this action.pic.twitter.com/iXWJGRw0Sm

        When the TCPDUMP action is sent, the LogBroadcastReceiver will start the LogCollectService. In the onStartCommand method of LogCollectService, the method setTcpdumpLogCat is called with the "status" and "cmd" extras.pic.twitter.com/f1hSaXpIWo

        This method will start a tcpdump capture if status is equal to 1 and save the log to /data/log/android_logs/tcpdump.logpic.twitter.com/MEhE90Px8y

        To summarise: 1) An app called imonitor is installed in the #HuaweiP8Lite 2) This app is running 3 services all the time 3) @HuaweiMobile implemented, on purpose, for the Huawei and system app use only, the possibility to dump all the internet traffic

        Of course, this is not the only one feature of this app, I will come back to this app later.

        Huawei claim that it is part of their antivirus.

        Here's a link to that claim https://forums.androidcentral.com/ask-question/844890-why-does-imonitor-show-up-app-usage-when-i-dont-have-app-installed.html … Additionally, I have a huawei p9, and can confirm it also exists on this device.

        Thank you for the link. This is not an official statement and it's a lie from the representative guy. This app is not an antivirus app.

        Definitely a lie. It can't be believed by a thinking person. I'll dig for an official mention of the topic from huawei on Chinese forums ect. Force stopping the monitor app has no negative affect for me regarding the workings of my phone - including the "AV".

        Also, by force- stopping imonitor doesn't stop the data traffic to being sent. The Storage used of Internal Storage is increasing bit by bit from a few kB to MB.
