[Q] Listening to data traffic - General Questions and Answers

Is there a way to monitor an app's internet data traffic? I am specifically interested in which webservice (URL) an app is calling, and what data is passed to it from my device. I have found some network monitor apps on google play that tells you the URL, but not the details of what data is passed, rendering it not useful.
thanks,
Joe

Access data from another app with Zooper?

I am trying to create a better view of my cellular data usage using a Zooper widget. In the past, I have just looked at #NTMTHM7# (since my plan resets on the 7th), but that does not take into account the shared data on my plan.
I have the data I want available in the MyVerizon data widget. I just don't know if there is a way to access that data for display in Zooper.
Any help (including other methods) would be greatly appreciated!

Fitbit/Jawbone/... hack

Hi,
With our smartphones and apps we already send quite a lot of data to third parties.
I am interested by a wearable device such as a Fitbit or Jawbone (to mention only popular ones) to track my daily activities but I don't want to send more data to more third parties. In addition, if one of these companies decides to stop some products or shut down their servers, these devices would probably stop working.
As they all provide an Android app to sync the smartphone and the device to fetch the data and display it, I am wondering why it would be requested to send data to their servers. Does anyone know if these app is working properly without an active connection to these servers? Is there any way to block these connections without a rooted phone? If rooted, do you think updating the hosts file would be enough to block connection?
Aside it, I am wondering if it would be possible to redirect this traffic to a personal server to fill a personal database? Is the traffic secured, via SSL for example, between the app and the server? We can imagine creating an open source project to be installed on our personal RaspberryPi (for example) to display data in a more friendly way on desktop without giving access to private data to big companies.

[Completed] Google services are CONSTANTLY downloading 6kbps of data ONLY when connected to WiFi

This has been asked numerous times and so far I haven't been able to find a decent response.
I made a post on reddit with more details and a screenshot: https://www.reddit.com/r/AndroidQue...stantly_downloading_6kbs_only_when_connected/
I've narrowed the culprit down to Google Bookmarks Sync / Google Play Services / Google Services Framework / Google Account Manager / Google Backup Transport. One or more of these packages (which share the same UID, so I can't tell which exactly) is ALWAYS downloading data, about 6 kilobits per second when connected to WiFi. When I'm only connected to 3G, there is zero unexpected network traffic.
Please direct me to an appropriate thread or provide any insight you may have.
I want to eliminate this unnecessary traffic, but I'd also like to know what this data is. Finally, on a somewhat related note, I'd like to know why Instagram and Facebook Messenger are also sending data at regular intervals, what that data is, and how to stop it.
Thank you very much
Hi,
I would guess that all those apps are only checking in, for updates, messages for the social media ones, etc. But you could try asking here for other opinions,

Can the work profile have access to my browsing history, device files, etc.?

I was recently admitted to a company, and as an ease of accessing my e-mails and work schedule, the android "work profile" was made available so that I could have access to company information (such as e-mails, calendar, information and others) without having to receive a corporate cell phone.
However, my biggest concern is with the organization's access to my data. My organization that created the work profile, can have access to my browsing history, data on the device (such as photos, application files, etc.), time I spend using my cell phone, contacts, call logs, and other data personal profile?
I have already visited the google instructions page, but I was still unsure because my organization installed some network certificates and the warning "Your organization can monitor network traffic ..."
Another question:
If I leave a work profile app open in the background, and use my personal profile at the same time, can my organization have access to network traffic and consequently my personal information?
All questions, however redundant, are intended to clarify the details of the organization's access to my personal information
From now on, I am immensely grateful for the help and time you spent reading my questions.
You are holding a phone in your hands for which an organization has concluded a data plan contract and is paying for it. They therefore will have a legitimate interest in the network traffic on this device, unless it is a contract for unlimted bandwidth. Network traffic is triggered by apps / services , which can actually be read out: they simply have to install a HTTP/S proxy what is intercepting the HTTP/S traffic on any app housed on the phone.

The phone is mine, and there is no plan
of internet hired by the company.
It's my personal cell phone, and for me to get
view emails and talk to people from
within the organization, I had to enable
the "work profile".
So I had my personal and work profile
on my personal device.
My question is: my company can see
my personal files and my online activity
in the "PERSONAL PROFILE"?

I created a second user on my phone named "Company".
If I do this it asks me if I wan't to turn on phone calls and SMS and then warns that
Call and SMS history will be shared with this user.

That makes sense, since I (as the owner) can decide whether or not other users of my phone can access that data.
I tried to access owners files via filemanager from "Company" account. I couldn't see anything.
I tried the same but via adb using a root shell -> I had full access to owners files.
Owner has a VPN active. I tried to access that VPN from within "Company". Didn't work.
Tried to access apps from within "Company" -> no luck.
Checked settings -> some are gone, some aren't. E.g. I can see my paired devices (paired from owner) when I'm in "Company" account.
Soo, to answer your question:

Access to browsing history, data, contacts? No.
Time spend? I don't know but in battery usage settings I can see how much battery has been used by the owner account.
Call logs? Yes, If you accepted that.
Your language? Yes.
About certificates: I don't know excactly what they do (I figured if you turn them off your device cannot connect to the internet anymore if that certificate is needed for that connection attempt) but you can go to Security -> Encryption & credentials -> Trusted credentials and turn them off while your in your personal account.
However: One questions remains: Does the profile your company created somehow differ from the one you can create manually via settings? I don't think so, so above things should be valid.
If that's an option you could also ask your company directly (even though I can understand if you might not want to trust them).
