[Q] Android app security

While I'm waiting for my GS2 (my first Android device) to be shipped I have been doing a little research into the apps and general security and was shocked to find that many apps actually leak private information and data back to ad servers. This scares me a little. I don't want my location, and other personal data being sent to places I haven't authorised.
Is there any way of being able to stop or block this or any way of identifying which apps do this? How can one know if a publisher of an app can be trusted?
I try to keep my PC locked down from this sort of thing and want to do so with my phone. I just want to be able to make an informed decision with Android.

There is a app called Permissions Denied that can do that.

When you download an app from the market, it tells you what permissions theapp has to have. Most of th time, the permissions aren't for what you think. Internet connection is usually cause it has ads. Also, see what the apps are rated, and read the comments to see if the app is trustworthy.
[sig]I'm close to root, im patiently waiting on those puzzles[sig]

First thing I downloaded when I bought my EVO was Lookout mobile. Very good AntiVirus app with free features that Sprint is trying to sell with their own junk. Try it out.

Thanks for the comments guys. The thing is how do you really know that the app is not maliciously harvesting your data?
Take the Lookout Mobile app triagetoday mentioned above. Now, I'm only using this app as an example and am not saying that there is anything wrong with the app as I've not used it. But it makes a good example.
The app wants permissions for everything. Most user comments are positive, there are a few that say that they cannot uninstall it which is worrying but generally the comments are favourable. But how can I be sure that this app wasn't written to harvest data on the pretence that it's protecting your phone? In fact there is even one comment suggesting just that. I can't see anywhere where I can look at the source code so is it a case of blind faith and hope the publisher is not malicious?
After reading many reports about huge increase in malware on Android and data leakage it's a real concern on how to protect your data.

[Q] How can I test an .apk to see if it's "safe" to install?

Hi,
Sometimes an app (.apk) is either simply not available through Google's store, or it might say "not compatible with your device", etc. There can be various reasons why a person might download a .apk from somewhere other than a "trusted" source.
If this was a file for my PC I could test it in a "sandbox", and I could scan it with both Microsoft Security Essentials and Malware Bytes Antimalware.
On my Android phone(s) I'm not aware of something like the "sandbox" option, and I don't really want to run an "antivirus" program on my phone. Is there an easy way to scan .apk files on the PC to see if they are rogue apps, might send SMS, "phone home", or otherwise mess with other applications or the system software installed on my phone?
Lets give another example: say I thought 15 minutes was not long enough to evaluate a relatively expensive Android game (it certainly isn't!) and I want to test it out first. Let's assume my only option in that case might be an illegally downloaded copy from unknown sources. Of course, we shouldn't do that. But if we did, how could we know if the file is safe and not risk installing some Chinese spyware?
About Android AV programs: anybody know how effective they are? Do some defend against "trojans" - I would think these days trojans are 99% of problems and viruses mostly a relic of the past?
My biggest concern is actually just unwanted crap that runs in the background which eats up battery, makes my phone warm (which I hate), or, perhaps even sends SMS message [this would be even worse because I don't have a text message plan].
EDIT: I see web pages with tiles like "new study finds Android antivirus apps not effective" and articles like this one: http://www.zdnet.com/blog/hardware/...bouncer-does-it-offer-enough-protection/17981
Do we have an easy way to boot Galaxy S3 off of "external" SDCARD instead of internal memory?

an easy way to check for safe apk
The easiest way to check for safe apk is to have one gmail account and another "whatever" email account. Then just send the apk from the gmail one to the second account, gmail always find viruses in any apk and stop the process to join the file (virus alert). Bad point is you are limited with the size of the file you wanna send.

Nowadays, even pc antiviruses can detect viruses in apks. I would rather not burden my phone with any android antivirus,since they are literally battery hogs.
sent using my HTC One S

Go here and upload the APK
http://anubis.iseclab.org/
Anubis is a service for analyzing malware.
Submit your Windows executable or Android APK and receive an analysis report telling you what it does. Alternatively, submit a suspicious URL and receive a report that shows you all the activities of the Internet Explorer process when visiting this URL.
Andrubis executes Android apps in a sandbox and provides a detailed report on their behavior, including file access, network access, crypto operations, dynamic code loading and information leaks. In addition to the dynamic analysis in the sandbox, Andrubis also performs static analysis, yielding information on e.g. the app's activities, services, required external libraries and actually required permissions.

Found a good one too
apkscan.nviso.be - give it a try. Drag and drop - wait for the upload - than click SCAN . Wait for a few minutes. That`s all. Unlike ANUBIS it has a resolution at the end of the analysis . Usually helpful.

You can also email the file to [email protected] and it will email the report back in about ten minutes. Virustotal can display some interesting info, for example it said that Lucky Patcher is a "Potentially Infected Hosts File (v)", as reported by VIPRE and AVware.
Virustotal also has an official android app.
The Netqin scanner is also an android mobile app.

Late answer, sure, but I think ClamAV is what you want. You also want its bytecode signature file, and to speed things up, you only want that single file (speeds up things quite a bit).
It is the only offline apk scanner i know of, and as for its efficiency i cannot say, but it seems like it is what you are asking for.
An alternative would be to install something like BlueStacks and remap your "Windows shared folder" (through registry) to the folder you have your apk files in, and then run BitDefender on it. BD is by far the most pernickety AV app out there for Android.

I'll have to check out bitdefender (it's also included on virustotal.com)
apkscan.nviso.be seems to be pretty good at analyzing files for suspicious activity, and it also uploads the file to virustotal for you. Then you can copy the sha256 hash into the virustotal's search, to get all the gory details.
anubis.iseclab.org limits files to 8 megabytes.
Another way to avoid malware is:
when installing an update to an already-installed version of an application, it will 99% of the time prompt you to update an existing app. There's been rare instances where some apps do use a new digital signature (for example when spotify had a big security hole, and for awhile there were two apps by spotify in the app store).
One other way to tell, as a final check when launching the apk for installation on the phone: the icon will not have the right icon. I've installed apps before that I thought came from a trusted source, but the icon was not right. In fact, I was considering not posting this publically, so the "bad dudes" would not update their methods.

Another tool I found:
http://andrototal.org/
Although it might be a duplicate of virustotal.

I just tried out this site. To me, it appears to be the most thorough virus testing site that I have seen. It takes some time for it to complete the scans. mainly because it scans the file with about 7 or 8 different scanning engines. Just just have to keep refreshing the page every few minutes to see if the results have updated.
I will be using this one as my go to site for apk scanning.

Just install it on the default emulator in the Android SDK
You can also install your apps on other emulator live bluestacks(best for games), jar of beans(best for rooted app) and windroy(the lightest)
Hit thanks if this helps

Use google scanning service VirusTotal to scan any app, secondly always use secure source. There are many well reputed apk sites but I personally use apklink.com , on this site required apk file is just a click away and its quite easy as well...
be safe & secure

This threads out of date, but it has me thinking I want to use something as mentioned in several replies to OP.
Are there any sites, or apps that can warn me if an .apk (for example) has malware etc.?
Thanks in advance for any help, including a link to another discussion that may have my answer

Securing adroid devices as much as possible.

Hey guys!
I'm given the task of securing 2 android devices (galaxy tab 7.0 and an S3). The friend of mine who has asked me to do this has been hacked (on an Iphone and on a windows PC) recently (for various sinister reasons) and After I secured her windows environment she bought these devices. A while after using the phone someone started to remotely control the phone and typed 'hell' in our language and she is really afraid. One of the pcs I secured has been stolen since it couldn't be reached remotely anymore, so I guess the threat is pretty serious. Now getting to the point, what would be the BEST way to do this ?
-Flashing custom roms on these (which is the most secure?)
-Seting up an antivirus + firewall on both devices (also I'd like to know which of these are the best NP if its paid)
-Setting up an anti theft app (and same here, I know Cerberus, but I'm wondering if there is a better solution)
The hard part of this is the fact the hackers are very likely experts (they hacked her Iphone back then making it taking photos and logging all keys like a regular keylogger).

What a story!
I strongly recommend avast! AntiVirus which comes with avast! Anti-Theft. Best Part: It's free!
McAfee is supposed to detect more malware but not as many as it would be worth its price.

Thank you Buddy! Any additional professional suggestions? Anyone?

Anti-virus is only a curative solution, and can only detect malware after they have already breached your device. Android's security model makes it difficult for an attacker to remotely breach the device, unless they have a bad app installed on the device. When a user installs an app, they give that app certain permissions, and these permissions need to be checked to ensure they aren't being used as malicious apps (why would a camera app need to make phone calls on your behalf?) . The best suggestion would be to exercise good permission checking habits to ensure you aren't accidentally installing a bad app. Also, attackers may also send bad code through SMS, which may appear as a clickable link. I could keep going on possible ways to get compromised, but these are the most prominent.

Internet Security apps

Hey !!
Do Andriod phones need antivirus or internet security as a must? If so provide me some links..
Thankxxxx in advance

The Answer Has been moved to a thread dedicated to security question and other advices to modify safely our Android Devices
Here is the post

Raiz said:
It absolutely doesn't, please don't download them, those are mostly commercial sh*t apps full of ads that plays with the fears of users.
Android Security advice :
• Just don't install apps that you don't trust (apk files and weird looking Google play apps)
• Never share your passwords with somebody not trusted, use a different one for each of you accounts.
Find more here :
https://forum.xda-developers.com/general/security
General security and privacy:
• a VPN isn't a magic app that allows you to go completely invisible, even I can find who you are simply by using your latest Instagram post, the government doesn't have money to spend spying on you anyway
• Public WiFi internet browsing is like taking a bath naked around other people, everybody can see what you're doing and can interact with your browsing by sending you pop up messages on your browser. In that case the VPN is useful. But please don't use anything other than your WiFi network to pay online.
• Change password at least once a year
• For God sake be careful on what you share on social medias !
• If someone blackmails you, just ignore him even if he show you he has your real password/footage of you doing nasty things, most of the time they haven't and tries to scare you. But take action on your account, just don't answer them.
• Not having any of your IRL infos online is a good idea, but it tends to be more and more difficult because of Google assistant, and other Google services that are super intrusive (I mean even with your YouTube Google know your tastes better than your buds). But don't panic, if you're not a terrorist or a criminal you're not risking your life.
Keep in mind that your security is fine most of the time if you have solid password, and you don't give them away, but your privacy is not if you have a social media account of any type. If you post something on the internet, remember it'll stay forever out there, whatever you do !
App that I use to keep my Android phone in good health (install them sometimes to clean up/check on my phone's state then I uninstall them):
Google File Go (cleans files)
AccuBattery (check the battery health)
CPU-Z(has everything you want to know about your device)
When I need to backup an app's data or the entire app:
Titanium Backup
Here you go, I gave you very few the security advises, there are plenty more, don't hesitate to check the internet out for more !
Have a nice day

I have 2 edits to your suggestions
1. Change your passwords monthly, preferably using a password manager that suggests really hard random passwords
2. Swift backup is much newer and more efficient than titanium backup ever was.

Viruses don't really exist in android. You can be targeted with malicious code but that is only if you open, tap on or accept something without knowing what it is.
For instance, someone could send you a link or a photo that has malicious code embedded in it, when you open it or accept it, then the malicious code has access to your device and your data.
As long as you know that you are dealing with a trusted source, you should be fine. But, if you are the kind of user that goes all over the internet opening things without knowing what it is, you will quickly find yourself targeted by malicious code.
Become a responsible, informed user that is aware of the dangers and what kinds of things can be a problem and you should be fine.

[Privacy] Puttin' Google in the Goolag

Situation:
I have somewhat of a "love-REALLY HATE" relationship with Google apps and ecosystem.
On one hand, they are great at what they do.
On the other, it's like having a spy satellite overhead, given how much telemetry it does.
Question:
I'd like to cut all of the Google apps' internet, location, sensor and background activity access for good when not in use. Or at least spoof whatever personal data is being sent (Device info, location, activities, etc). Any way to do that?
What I've done so far:
My current way-to-go method involves installing RethinkDNS+firewall, then blocking every single one of google apps including Gboard. It sort-of works, but very inconvenient, as I have to manually enable internet access for a particular app and/or service when needed. I also tried edXposed's XluaPrivacy module to cut off access to certain permissions. Again, cumbersome.
After going through F-Droid, I found an app called "Insular", that claims being able to put all of the "big brother" apps (such as Gapps) behind an isolated sandbox, a digital gulag of sorts.

Thanks for the pointer to Insular whose advertising on F-Droid says:
Insular is a FLOSS fork of Island.
With Insular, you can:
Isolate your Big Brother apps
Clone and run multiple accounts simutaniuosly
Freeze or archive apps and prevent any background behaviors
Unfreeze apps on-demand with home screen shortcuts
Re-freeze marked apps with one tap
Hide apps
Selectively enable (or disable) VPN for different group of apps
Prohibit USB access to mitigate attacks with physical access
Click to expand...
Click to collapse
Based on that, I suspect this XDA thread about "Island" may be useful.
[APP][5.0+][BETA] Island - app freezing, privacy protection, parallel accounts​
"Island" is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted. Device-bound data is still accessible (SMS, IMEI and etc).
Isolated app can be frozen on demand, with launcher icon vanish and its background behaviors completely blocked.

Like you, my relationship with Google is strained where I don't set up any Google Account on Android and it works just fine.
I don't have a contacts.db sqlite database for that reason too, so my favorite communication apps are all designed to store their own contacts db internally to the app itself.
I replace Google apps with FOSS equivalents such as NewPipe (or, more recently, Vanced YouTube) for example.
And I spoof my GPS location by default (using Lexa Fake GPS, for example).
Of course, given I don't have a Google Account on my phone, I use the Aurora Store instead of the Google Play Store. Of course, I strive for apps that don't require Google Framework Services (GSF) which Aurora neatly filters out for us.
Since I'm not rooted, I can't delete Google Play Store, but I can disable it, which is almost as good.
And, I use privacy-aware apps for my messenger, calendar, contacts, and dialer apps (many of which come from Simple Mobile Tools' suite which are available on F-Droid).
To keep my WiFi SSID/BSSID/GPS/Strength/etc. out of the hands of Google (& Mozilla and Kismet and Wigle, etc.), I add "_nomap" to the SSID and I turn off the SOHO router SSID broadcast (which "hinders" most cellphones from uploading my BSSID information to Google public servers); but then I have to also turn off "AutoReconnect" on Android 12 and also I have the Developer Options set in Android 12 to randomize the MAC address on EACH connection; however that means I need to set any "static" connections on my LAN from the phone and not with address reservation on the router (which typically utilizes the MAC address).
And it's not just Google we need to keep our data out of their hands, as I even use WhatsApp privacy aware tools such as the WhatsApp dialer and WhatsApp Click to Chat mechanisms (to keep my contacts out of Facebook's hands too).
For offline maps, I use a quick web browser lookup on a privacy browser (such as Tor or Epic or Opera), since the Google address lookup is still the best in the world... (which is the love/hate relationship, right?)... and then I paste the GPS coordinates that the privacy browser found on the maps.google.com web site into a local routing application (such as a shortcut to a browser to google maps on the phone or better yet, to a dedicated offline map program such as OSM And~), and even traffic can be gotten without Google (e.g., Sigalert & 511 apps).
I used to reset the Advertising ID with a homescreen shortcut that could be activated from Windows via a batch file over Wi-Fi, but now with Android 12 we can wipe out the Advertising ID altogether (i.e., reset it to all zeroes). However, I still periodically change my GSF ID and other supposedly unique identifiers.
I'm still trying to figure out the implication of "trackers", so if anyone has more information about them, please advise.
Off hand there must be scores more things I do for privacy, where we probably should have a main thread on this site of all the myriad things people can do to increase their privacy on Android (some of which I've screenshotted for you below).

I try to put effort into the response so that others can benefit (but nobody ever presses the like button so maybe it's not worth the effort).
For example, when I mentioned I spoof my GPS, I looked up the app I used and linked to it so that you wouldn't have to test a score of apps like I did to find the best one.

That was just off the top of my head where there has to be at least a hundred different privacy things I do on Android to distance me from Google that most people don't bother to do.
I admit, sometimes it feels like we're putting a dozen locks on the front door, but in the end, we LEARN a lot about Android in the process.
A lot of the protection is to protect ourselves from others who don't know how to configure their phone, so they are uploading our private information (like our contacts and home locations) to Google databases.
For example, the typical Android phone when it drives by your front door uploads to google your exact location, your signal strength, your unique BSSID and your SSID... where you'll note in my response above I had to do a half dozen things on my phone and router to prevent that from happening (i.e., just adding "_nomap" doesn't work but most people don't realize that because they don't think about it).

I'm sure there are plenty.
But I have been in MANY situations where there are none.
Take, for example, changing the GSFID... almost nowhere on the net is that described how to do it. Almost nobody does it, but it can be done if you know how.
I really should write a set of privacy tutorials so that everyone can do it but I have to find the time, and this web site doesn't like text tutorials I found out recently. So they make it a PITA in the end to help people. Sigh.

Click to expand...
Click to collapse
If you look at the links I gave you in my response for contacts, gps spoofing and privacy-aware WhatsApp, you'll get a good start.
A quickie is to not have a contacts.sqlite database, which means you need your own contacts.csv or more likely contacts.vcf file, which you can maintain on the PC if you like (works with Excel for example).
Now that you don't have a contacts.db sqlite database, you need to find the contacts and dialer and mms/sms apps that can suck in their own contacts.vcf file, which I pointed you to in the Simple Mobile Tools suite.
For GPS spoofing, I didn't mention you need to turn "Mock Location" on in the Android Developer Options, but that's what most people already do so I assumed you knew that. Once you turn that on, you can just select the mock location app of your choice (where I suggested one above which isn't perfect but none of them are).
That particular app moves your location every few feet and it gets the altitude and it can easily be stopped and started, etc., but I'd like it if it didn't move just "west by 10 feet every minute" but instead if it would follow a pre-determined route that I could give it. So they need a lot more work to be as good as we'd like them to be.
For What'sApp privacy, look at the two apps I linked to in the prior post as they don't need the contacts.sqlite database to work.
Your WhatsApp should only have an icon in your folders for the people you contact and nothing else, IMHO. That's the best privacy you can get, although WhatsApp does decent hashing on the contacts file when it uploads it to their servers - but still - why give them your entire contacts when you only contact 10 people (or whatever) on WhatsApp. Right?

Funny you mentioned microG since I installed it for the first time yesterday when I was setting up Vanced Youtube based on this thread.
I generally choose apps that don't use GSF but sometimes you have to use a GSF app (e.g., Zoom meetings), and then it's nice to use MicroG instead of Google Services Framework.
I only installed it yesterday so I really don't know how well it will work for me as I didn't even need to install it to install VancedYoutube. You just need it to log into YouTube but I never do that anyway.
In summary, there's probably a hundred things we do to our phones to set up privacy but I'd have to write each one up in detail to help everyone and that's a lot of work.
Especially if almost nobody reads these threads.

Thank you for doing God's work out there. Ethics like these are what creates the content that keeps the internet from becoming a dumpster fire otherwise. Tutorials and explanations that come from the fellow users are THE best and usually directly on-point.
When I was just starting setting up Linux environment, I wrote "how-to notes" on every successful step. At first it was more like the "sticky notes" to help me remember, but eventually (as the list grew) I started writing these tips in a way as if they were to be read by someone with little background in the subject. What used to be the "Linux notes" file became 10563 lines monstrosity now... So every time I need to answer someone's question I just copypaste from this file.

Absolutely. I've spent about 2 weeks tweaking my new phone (Nokia X6), trying out different roms/recoveries and app setups. Pissed off a bunch of people in the process - most wouldn't understand that I'm setting up a system to last another 7 years, just like my previous phone (Galaxy Gprime). Not to mention that with the amount of sensitive info on the phone, security and privacy are a legit concern, and worth learning about just how one learns to install and use the lock on the front doors.
Phones became disposable both in software and hardware, and so have the general attitude towards the devices.
My final setup became AOSP PixelPlusUI Rom (comes with about openGapps nano worth of Google stuff) with most other stock apps (contacts , dialer, keyboards, msg etc) removed via ADB and replaced with F-Droid alternatives.
I've also used Rethink DNS with whitelist set up/AppInspector to put Google in the Goolag - no internet access for anything google-related at all times. So far my phone has 253 apps blocked (including almost all of the system apps). Surprisingly, all of the necessary apps off google play store (Whatsapp, FB messenger) still function well. Whenever I need a particular Gservice (like a translator), I just enable access for that (and only that) until I dont need it anymore.

Funny you mentioned microG since I installed it for the first time yesterday when I was setting up Vanced Youtube based on this thread.
I generally choose apps that don't use GSF but sometimes you have to use a GSF app (e.g., Zoom meetings), and then it's nice to use MicroG instead of Google Services Framework.
I only installed it yesterday so I really don't know how well it will work for me as I didn't even need to install it to install VancedYoutube. You just need it to log into YouTube but I never do that anyway.
In summary, there's probably a hundred things we do to our phones to set up privacy but I'd have to write each one up in detail to help everyone and that's a lot of work.

I will give microG a try (in a form of LineageOS for MicroG). In fact I did install this rom before but I was a bit confused about what it did and assumed that it is a regular LinOS repack with Gplay store and apps built-in. Time to test again.
Especially if almost nobody reads these threads.

Threads like these is how I passed my uni exams. Not even exaggerating XD. Thanks again for a very detailed insightful read!

Hello my friends, very happy to meet good hearted people who think alike about Gugle.
as my name suggests I'm noob still and didn't understand much of discussion but very happy to meet you friends. My love & warm regards to all here. Here is what I did uptill now before I saw this thread :
1> Load GSI/ROM.
2> Load TWRP
3> Load Magisk
4> Load microG
5> Install Service Disabler
5.1> Disable bunch of internal services like telemetry, analytics, location (FusedLocation not possible to disable) for every app (3-rd party & system app), contacts sync etc.
6> Install SD-Maid Pro
6.1> Freeze apps like Gugle Calendar Sync Adapter & Gugle Contacts Sync Adapter
7> Install CIAFirewall Fake VPN & configure it.
8> I use Opera browser for Banking, Youtube, Cab booking, Surfing, Gmail, Food Order etc.
9> Install Aurora Store for general app management & installation
10> For contacts I save all contacts in notepad app, and let all calls purposely bounce then I call back aftter checking whose call it was & state false apologies.
#FYI :- Gugle, Mycrowsowft , eFbee are not really to be blamed, rhey are having to comply with FBI, Phentagon, Central Intelligence Agencies, Interpol, etc. or they have to shut bizness.

Like you, my relationship with Google is strained where I don't set up any Google Account on Android and it works just fine.

Hi, I’m glad to have found this thread as I’m not happy with how my normal Android phone is spied upon by google. But I’m not technically knowledgeable and I don’t want to risk bricking my phone by trying amateur attempts at rooting, or installing Insular, etc…
So far I have not signed in, I allow only minimum permissions, use Netguard, Aurora and FDroid, and have disabled bloatware. I also force-stop apps as much as possible when not in use, and enable Location and Bluetooth only when needed.
I know this is just an amateur, token attempt to reduce spying - so I may have to eventually buy a degoogled phone.
I’ve also done some of the privacy suggestions in the attachments you posted.
Could you help me with a couple of newbie questions…
1): I might have minimised some personal data harvested by most of the apps I use, but I guess my privacy precautions will have no significant effect on the amount of telemetry collected by google?
2): If my precautions really have no significant effect, I’m wondering if would it make any real difference if I was signed in as I don’t use any of the google backup services anyway?
Thanks.
