[Q] General Security questions - Security Discussion

Running a Samsung Note 8- GT-N5110 rooted with Slimkat 4.4.4 build 9 official as the rom. Kernel is 3.0.64 SlimKat g9913. Firewall is AFWall+. I do not have Gapps installed and get pretty much everything from F Droid. Developer options enabled. Tablet is encrypted. E Mail client is KMail. Browser is Lightning 2.5.1.4
My concern is the number of internet connections from System when browsing. Normally with only KMail running and Sync enabled I will have 4 connections- a couple from system to the local wi fi 192.168.xx on different ports I assume for DNS &c. KMail will have 2 or 3 connections as well. However when I browse there will be sometimes 20 connections from a number of places in the US and elsewhere, Ukraine for example, earlier tonight.
Pretty much everything installed appears to obey the AFWall settings and I am prone to enable a connection for an app when I need to use it and disable it when done. The System connections bother me because I am not completely sure what they are doing. the 20-30 connections when browsing is a larger concern especially given where some of them are- I use OS monitor to monitor connections and also have Network Log from the F Droid site installed as well for more detailed sniffing. What I am trying to do is build a secure platform to use for business e mails to a secure encrypted account. Any suggestions would be appreciated.

[Q] 3.1 Proxy for apps?

So, I am really glad that you can now set the proxy for individual connections so that I don't have to keep switching on the proxy at university and switching it back off when I get home.
But my main issue is that the proxy only seems to work for the browser.
When the browser connects to our proxy, it asks for my student number and password, and then it allows my through the proxy and I can browse the net.
But with 3.0.1, gmail and the other apps still couldn't get through the proxy, as authentication seems to be only for the browser.
I assume it will be the same with 3.1, but will have to double check on Monday when I go in again, as I only got the update today.
The android developers site that has the list of fixes for 3.1 says this:
"This proxy configuration is automatically used by the Browser when the Wi-Fi access point is connected, and may optionally be used by other apps."
So my questions is, how do we access the "optionally be used by other apps" part?
I don't want to root to use 3rd part software.
Thanks
So. Ya, that apps still can't access the internet.
Except for google maps, that seems to work, although I'm not sure if it has just cached maps or not.
Anyway, there should be a way for the apps to use the same authentication as the browser. The proxy is supposed to be global on the device, so how do you make the authentication global too?
Anyone have any ideas? Or know who I can contact to get an answer/fix?
This is very frustrating. What's the point of having a proxy if the apps don't work, especially in android; an app centered OS.
Thanks

[Q] Facebook for Android unable to load Profile over WiFi

Hello there,
I've stumbled upon a problem with my new Sensation & the Facebook for Android official app.
Basically, certain parts of the app - namely the Profile page (would be your Wall in a normal browser) will not load/refresh over a WiFi connection.
Facts I have established are:
- Entire app works when WiFi is switched off & handset just uses 3G/mobile bb.
- With WiFi on, Newsfeed works, contacts work, everything works but your Profile feed. You can look at your info & your photos no problem, and changes are reflected. You cannot post status updates.
- Several different WiFi hotspots used, same result
- FB working fine on laptop clients using same WiFi hotspots
- FB for Android working fine on my gfs Desire using same WiFi hotspots
- m.facebook.com & full site work flawlessly
- FB for Sense (Friendstream, Sync & Sharing) works fine
- Exact same problem noted with Friendcaster - login screen wont show with WiFi enabled, once on 3G - login page shows up fine.
- Multiple clearing of accounts/cache - uninstalling update, testing, reinstalling update & combinations thereof - all fail.
- Checked FB Privacy & Account settings - made sure HTTPS is off etc.
So, essentially various parts of FB are not contactable using some official & unofficial apps over WiFi, but operate fine over 3G.
This is a Sensation from Singapore - just had an OTA update - 1.35.707.1 - which didnt make any difference (problem existed out-of-the-box..and the box was opened last Tuesday).
I've seen other threads vaguely pointing towards this issue on other handsets with various rom revisions, but nothing concrete with the testing I have done above.
Anyone got any bright ideas - or is it just a bug in a common API used by these apps or something...?
Has anyone else even noticed this issue?? Or am I just going mental...?
Cheers
After much mucking about, I traced this issue to a NAT translation problem with my wireess router. Effectively transacting the mtu down to 1100 for some reason. It was a glitch.
Saving config + Factory reset + loading saved config was the solution.
Sent from my HTC Sensation Z710e using XDA App
I had same problem. After change setting of my router, problem solved. Try change dns to 8.8.8.8 and 8.8.4.4.
I got the same problem. Done everything but its useless 'n I 'm going to mad just like the initiator of this thread.
MTU
wasi99 - check the MTU on your internet interface on your wan router; I have seen this problem several times now and always has been due to incorrect MTU for the internet connection in question.
For me, in the original post, I was on an ADSL2 connection, and the modem had its MTU set at 1500 (which is correct), however, my router internet interface was set to something weird like 1400. Once I changed the router internet interface to be 1500, all was well in android app land
Some things are more sensitive to incorrect MTU than others. You might be able to load www pages fine, but not be able to ftp to certain sites - for example.
Hope this helps, and saves some hair!

Thank a lot mate! It helped

Got my GT7+ yesterday and have a couple questions. Brightness? WiFi?

Edit: This is the Galaxy Tab 7 Plus 4G w/ TMobile...
So far I am loving it. I have had a plethora of Android tablets, including the Galaxy Tab 10.1 (until yesterday), and the original 7" Tab. Here is an issue I have not run into thus far...
Issue 1: I like my brightness settings to be %100 all the time. I always (almost) have a power cable with me, so I'm not worried about the drain. I have the auto setting turned off as to keep it from adjusting on it's own. However, everytime I open the status menu with the brightness slider, it is down to about %90-%95. I can't get it to stay on full. Also, and even more annoying, every time I open the browser, the brightness drops to like %30'ish and I have to open the status menu and slide it back up. The browser is where I REALLY need the full brightness the most, and it's the biggest issue.
I noticed this out of the box, adjusted settings, nogo, so I factory reset, and same issue. This is leading me to believe this is just a setting or something I am missing. Any ideas?
Issue 2 (THE BIG ONE): This Tab 7+ can't see my work wifi. It connects to my wifi at home just fine (did last night at least), which is also WPA, but it doesn't even see the one at work. It acts like it isn't there. In fact, and this is probably important, it is not seeing any networks up here, and there are at least 10-15 that should be visible from my location in the building (all but a couple from other companies). My G2x (Android 2.3) is connected to my work wifi just fine, and it sees all the others around us, the the Tab 7+ right next to it sees none. I also turned on the wifi router on my phone, it will not see that one either. I've verified the wireless is enabled, as well as turning it off and on multiple times and many reboots, nogo... I need it to hit the wifi at work and home so it isn't sucking my 4G data, so this is a big issue for me.Any ideas? I'm at a loss...
Also, to answer before it's asked: Nope, it's not rooted. I may do this at some point (as I do most of my devices), but for the moment I want to leave it stock and not mess with it. These issues seem like they should be resolved/nonexistant in the stock ROM, so I shouldn't have to root to fix them. Please tell me if this is incorrect...
Thanks for any help, sorry for the long post...
(pardon typos, I'm at work and multitasking, no time to proofread)
on the brightness broweer tip. use a different browser. its a known issue that the stock browser automaticaly dims the screen.

Thank you... You're right, it doesn't happen in Dolphin, however I am one of those weird people the really prefers the stock browser...
The biggest issue is the wifi not showing up. I am updating that issue with more info now...
what channel is the wireless network on? i had a similar problem on my windows laptop, it cannot see the wifi.. turned out that my wireless card(the driver actually) cannot see any wireless network beyond channel 12.. who knows you're having the same problem, might worth checking.

Ours is on 6... Thanks though
for me it was the opposite, it could see my home wifi, but not my work.
only was to solve it was to setup a static ip at work for the GT7...
I called samsung, they said its a problem with some routers. No eta on fix other than static IP.

Just to chime in - I also have the same problem connecting to my work wireless network but I think because it uses a SEPARATE authentication scheme.
The way my office WLAN work is like this:
1). Connect to the WLAN with SSID "Office", no encryption password required
2). Once the Tab is connected, it WILL receive an IP address
3). Open up a browser (Dolphin, etc.) and try to go to any website (Google, etc.)
4). Instead of going to the website I typed in in no. 3, an authentication page will show up
5). I need to enter my Windows AD account and password
6). If its successful, then I can start browsing the Internet (but not going to the Internal network, that requires VPN access).
Step 3 is where the Tab FAILED to do so. It just doesn't want to get redirected to the authentication page.

Yep, same way for me at work. OP did you try to manually add the wireless info vs letting the tab "find" the access point?

Also, here is a strange thing. About 2 hours ago it notified me there were wireless networks in range, and then showed me 2 random networks from another office. Suddenly, it saw nothing again. Then about 5 minutes ago, while I was in the bathroom ( ), it suddenly showed me ALL of the surrounding networks. Yay! I tried to connect to the one I use, it took my password, but never even attempted to connect. Then, they are gone. Now it doesn't see them.
What. The. Fuuuudge.

[Q] Random connections in Lolipop

So I've reinstalled a pretty minimal Lollipop rom recently, didn't install any of the Google things and use F-droid exclusively.
From Network Log:
https://f-droid.org/repository/browse/?fdfilter=Network+Log&fdid=com.googlecode.networklog
I can tell what all the connections from my phone are doing and they're indeed what I wanted, except for a bunch of HTTP connections which show up randomly whenever I do anything that is network related, and they seem to be retrying in the background. Network Log shows these are from the process (1000) PPPreferences, to 54.xx.xx.xx:80. From Whois these IPs are owned by AWS and by connecting there directly it show it's their cloud front (e.g. http://54.192.137.127/). Occasionally it would also try to connect to an IP owned by Google (216.58.221.142:80) and an IP owned by my Carrier. These connections would show up if I'm using anything but the "System built-in" logging method. Does anyone have any idea what process or service is making these connections?
Obviously it's not PPPreferences, since I've downloaded the apk for the version for my OPO, decompiled it. It has nothing to do with network and it's definitely not making any connection. So I suppose it is being mixed up with other processes, in AF+ firewall, the following processes got mixed up into the same group:
PPPreferences,
Android System,
DeviceHandler,
Settings Storage,
QuickBoot,
Input Devices,
Phone,
Key Chain,
Settings,
LocationServices,
Fused Location,
com.qualcomm.timeservice
It's not a huge problem because from the connection log, the firewall is stopping these connections properly, but I wonder what it is. If it is related to Google provided services, why would it still creep in when I've gone through all the length of installing a rom without Google Play and Gapp, that's worse than Microsoft or the former Doubleclick in their worst days.

No VPN on Marshmallow

After I updated my sprint galaxy s6 edge to marshmallow OTA, VPN is not working for me. I have tried more than 5 different VPN apps, but none of them work. They say they are connected, but as soon as I switch to a new app, they stop working. VPN worked fine before I updated, but now it is not. Please help!

I've got this problem too, on chinese 9250
Go to Settings > More > VPN
Set up your VPN in there. I've set up VPN on my Galaxy S6 and S7 using L2TP IPSec with a signed certificate from GoDaddy.
I had it working on the S7 with a PSK also. Both phones are running Android v 6.0.1 Marshmallow.
It's strange but the VPN connection settings are different. My S6 is a Sprint phone, and I can't assign it a Certificate Authority. But the Verizon S7 won't let me save the VPN connection without a CA. I have to install the certificates in different ways for each phone as well. Very odd.
Anyway good luck.

Could you tell me how to do this please?
same problem for me Samsung s6 edge android 6..0.1 VPN apps work.... cyberghost / opera max/ and the rest .
PS after Zamber88 suggestion go to settings>> battery>app power saving > turn off for opera max or other vpn app.
PPS: if that is not enough do this: Settings >>Battery >> Battery Usage >> more (right up cornet button) >> Optimize battery usage >> select All apps and choose your VPN app and turn off .
also if in OPERA MAX when u use mobile data u get the error "enable background data " is because of the power saving.
CASE CLOSE !
That's a really strange issue. We did a lot of testing on MM with Nexus devices and everything works as intended. We even have a S6 Edge with MM that works fine (SM-G925F with one of the Unknown build listed on sammobile IIRC).
All I can come out with now is that you could try checking if there aren't any battery saving features interfering with the VPN apps.
Solved.
S6 edge.. disabled powersaving features. Vpns are working fine. Strange but cant figure out how powersaving is meddling with vpn. Solved.
Its not power saving . its restrict background data . just off the restrict background data and will work fine

I'm not sure if anyone can help me over here, but I'm not finding anything in the Nexus forums. Since @zamber88 did MM testing with Nexus, maybe you can help me with my Nexus 6. I have a 10 day trip to China coming up in a couple weeks and really need to get VPN working.
Google searches haven't helped, except to point me here. I have purchased VPN Unlimited and tried it with their app and an OpenVPN app. I got a free Galaxy J7 as a spare through the T-Mobile promotion a while back, and both apps work on it with no changes at all. Neither work on my Nexus 6, despite turning off power saving and restricting background data for both apps.
When I select a server, the J7 the Allow connection pops up, I OK it, and connect. On my Nexus 6, the refused to grant permission pops up. See the attached screenshots.
Any help would be greatly appreciated.

I'll try to cover all of the bases from easiest to most cumbersome. Given you have some time on your hands this should helpful. Read through the list before doing anything and once you start doing stuff note it down as you're going so that we'll be able to pinpoint any other problems that could pop up. If you succeed then you'll have an answer pretty much ready for posting .
Reboot. Sometimes freshly installed VPN apps fail exactly like the screenshots show.
Try setting up a VPN connection with another app. Shameless plug: Opera Max, Opera VPN (note: there's an issue in Max which makes some VPNs disconnect after a couple of minutes so make sure to kill it before running any other VPNs).
Scan the device with Avast, AVG and Avira to rule out any worms.
Rule out any other apps interfering by booting into safe mode and try connecting again (with your app and, Opera Max for a sanity check).
If you don't want to commit to steps that will follow (or the step before this one succeeded) remove apps from least to most needed retesting with your app and Max after each uninstall.
Upgrade to Android Nugat. It shouldn't break anything and could potentially fix this issue. Either ways it's always a good idea to upgrade when updates are available. It's not like you're on iOS .
Now it's a god time to make a backup (frankly, anytime is good for a backup). If you went over with uninstalling apps making one will be easier. If you have root on your device you probably have TWRP, make a backup with it and download it to your PC. You could also make a Titanium backup if you're not big on setting up basic apps but it's optional. If you don't have root just backup all sensitive data (photos, videos, settings if it's possible to export these in-app). Also note down all apps you can't live without. Google Play has a history of installed apps but going through it is a pain and the "Copy settings from another device" option when setting up a fresh device is helpful but will not restore in-app settings. Also I would advise to not use it given that the culprit can sill be lurking in your apps.
MAKE THAT BACKUP, there's no going back from here . Do a factory reset. After that as mentioned before don't restore settings and set up a "new" device. Set up your accounts and check if both VPN apps work (they should by this point). Now start installing your basic app setup and after configuring each one make sure that the VPN still works.
If somehow this didn't help make sure you're not running a ROM that's botched by flashing the official system image (and upgrade to Nugat as a bonus). If you know what I'm talking about then you will know how to do it, if you don't know AND the issue still reproduces the there's something really strange going on.
By now you should have your issue solved, hopefully in the first three steps at most. There's one other thing to take into account. The great firewall does not like VPNs and there's a fair chance that Unlimited VPN will not work so be prepped to have a backup plan. You could try with Opera VPN (no idea if it works, not my project, would be nice to get feedback) and also get a trial for any service that looks interesting to you on this list.
Hope this helps and that you'll have a safe trip .
UPDATED minutes after posting:
One simple step I missed: reboot. In most cases it solves exactly the issue you're having. No idea why it happens but probably there's a 2y bug opened and tagged as low prio in the Android project .
Thanks for the quick reply!
1. Besides VPN Unlimited, I've already tried OpenVPN for Android and OpenVPN Connect. They both use .ovpn files from VPN Unlimited. I just installed Opera VPN and whether I swipe through the intro screens or skip them, I can't click on "GOT IT"; nothing happens. I think this might be the crux of the problem as some of the buttons in the other VPN apps don't respond either. I'm "almost" positive it's not a screen overlay problem because I used to use f.lux that did that, got rid of it, and haven't had any problems since.
2. I run Lookout Security & Antivirus and just scanned again to be sure. Nothing found.
3. I tried safe mode earlier, only to learn that you can't install or run any aftermarket apps.
4-7. Nougat hasn't been released yet and I'm too dependent on systemless root and Xposed, I'm still stock rooted on MM 6.0.1 with the September security update. I do run TWRP and Titanium Backup and make sure their backups are up to date before I try anything dangerous.
8. Unless you can think of why I can't click on "GOT IT" in Opera VPN, I guess my next step is to sideload the latest OTA again and try all of the VPNs before installing TWRP, SU, and Xposed. That's about all that's left.

1. Some of the buttons don't respond? What about Opera Max? Opera VPN is fairly new in the game and it still can have issues (though I haven't found any during the brief time I was testing how it works with Max). This sounds really strange. Does it happen in other apps?
2. Rerunning the same Antivirus app will not double the likelyhood of finding a thread . Try with Avast too. You can safely uninstall it after that.
3. What aftermarket apps you have in mind? APK's installed not from the Play Store? It shouldn't impact testing if Unlimited VPN works fine. All background stuff shouldn't run by definition in safe mode.
4-7. Nougat is released. After beta 4 they started releasing OTAs and images for the final release on the beta channel and now it's going to go global. There are factory images for Nexus 9 which I upgraded recently and we have a Nexus 6 but after checking it looks like got the OTA from the beta channel, so it will take a while for the official release to roll out to 6 (though 6P and 5X already have it). Also you're right, there's no systemless root for it yet. We're rolling standard SuperSU on test devices in the office (no need for Android Pay or banking apps there).
8. I'll reach out to the VPN guys for info on gathering debug information for this. Meanwhile try with Opera Max or even Betternet. Do these also fail to connect? Also does it reproduce on mobile and on WiFi?
Got a response from the VPN guys. Most probably your network blocks VPNs. Try pinging http://api.surfeasy.com/ from mobile and WiFi. If it doesn't go through then your network provider is blocking it. Probably it will be the same case for other VPNs. The issue is known and they'll probably add an error message in the next release .

I installed Opera Max and it was the only app that gave me a helpful error message, so thank you and the coders for that! The message said something like it couldn't establish a VPN connection due to an Xposed module. I disabled Xposed, rebooted, and all of my VPN apps worked. Further searching found this thread saying that Xposed's Immersive Mode was the cuprit. http://forum.xda-developers.com/xperia-z2/help/vpn-to-t2850981
I re-enabled Xposed and disabled only Immersive Mode and VPN still works. Hopefully this will help others in this thread too.

I re-enabled Xposed and disabled only Immersive Mode and VPN still works. Hopefully this will help others in this thread too.

I missed that you mentioned Xposed earlier. We implemented Xposed detection to prevent abuse so it's good to hear that it helped you to resolve your issue . Thanks forwarded to the developer behind it . Enjoy your trip!
