[Q] Phone seems to be infected by a Trojan - Nexus 4 Q&A, Help & Troubleshooting

A few days ago my phone arrived from Ebay. I set it up and all was OK until I put it on the wireless charger. Then I noted that someone started to remotely operate the phone - to switch applications and so on.
During the set-up I upgraded to 4.3 and installed stuff from big and known companies (Facebook, Microsoft, etc.), all from Google Play. I haven't installed anything else. Usually I am very careful with what I install on my devices because I've been developing software for long time and have some experience with security (although this is my first Android phone).
After I noted the issue I restored the phone to its factory settings, installed even less apps, however I experienced the same. The hacker even wrote something playful.
Could you pls tell me how to find out what is going on? Like how was it possible to put a Trojan that would survive an Android update and a factory restore? How to find the Trojan and so on. I later installed some antivirus/antimalware that reported that the phone is clean.
Thank you.

Weird! What did the hacker wrote if I may ask?
I assume this is AndroRat, you can google on how to remove it (I wouldn't know).
Keep is updated!

Factory restore doesn't touch tree system partition, so if the offending app was placed there resetting won't do anything.
Download the factory images from Google and flash them. It will revert you to complete stock

Disconnect it from the net whilst you investigate to protect data
Sent from my Nexus 4 using xda app-developers app

as said above disconnect from wifi and remove your sim card. First thing i would do is use one of the toolkit to unlock or lock bootloader (it completely wipes everything); then do a factory reset. That should do the the trick. If the problem persist contact the police.

Locking our unlocking your bootloader doesn't wipe everything. It wipes userdata. It doesn't touch the system partition. As I said previously. The only surefire way to ensure a complete wipe is either to fully wipe all partitions and install a custom Rom.
Or if you wish to stay stock, download the nexus 4 stock images and flash them.
Doing this will erase all user data & all system data
It will then put stock files back on

It seems like someone else is having the same behavior with their phone. Maybe it has something to do with the type of wireless charger.
Link: http://forum.xda-developers.com/showthread.php?t=2440115

It's probably just wireless charger bugging up the capacitive screen, try the stuff from above and when you flash a new image don't use the wireless charger for few days and see if it still happens.

[DEV] Security risk for rooted or S-OFF users

Hello guys. I've became very interested lately about the posibility of locking my phone in case it was stolen. There are plenty of apps in the market that either allow you to remote lock or lock on SIM change. But a user who has some experience with adb or recovery will always be able to simply do a full wipe and flash a new ROM, thus rendering the locks useless. The easiest way is to put a pin when trying to acess the phone with ADB or a custom flashed recovery(S-OFF users). Personaly I do not know if tracking apps will still work in this case so I hope one of you will be able to provide a answer. Also if you have other suggestions of how security measures in this situations should be implemented please tell me.
Honestly there is no way to prevent people from using your phone if its stolen. Its always possible to do a factory reset to gain access to the device. The reason to password protect your phone is to prevent someone else from accessing the data on your phone, which would be erased by doing a factory reset.

It really is an impossible situation - the best solution is either a hardware tracker or wiping data.

[Q] lost my galaxy s2 - utrack not active :((((

Hi all
I lost my galaxy s2 two days ago. I called my phone a few times until the person who has found it, shut it down.
Unfortunately I did not activate utrack. All I have my IMEI. Here in Switzerland only my provider does blacklist IMEI-Numbers, so that sucks too.
Anybody got any idea, or should I leave it??
There is not much you can do if you didn't activate tracking in phone(samsungdive) or use some aplication for that purpose.
Tracking is i think.by.default active if u logged in to samsung account

This app could have helped you, had you not called the number and warned the person that you are looking for the phone.
https://market.android.com/details?id=com.lookout.labs.planb&feature=search_result
if the phone is still on you can still try to install that app via the link above.
Sign into the market on your PC using your google account.
Choose to install "Lookout Plan B" to your phone.
If it is on and with network connection, with your data remaining, it should be installed.
if who found your phone know a little bit about android i think the first thing he does is to delete your gmail account to prevent you from install apps from the web...so if you can't lock by imei there's nothing else you can do i guess

hey guys
Many Many thanks for that great input. I am talking about Plan B. The chance that somebody knowing about android found it, isnt that big. I did install it over the market and it said, that its going to be installed, so i am praying for my luck know.
Will keep you guys up-to-date.
Thanks once again.
for all these things (Plan B and Dive) to even work the phone must be on, must be on 3G data plan service, or be on Wifi. If you had the data off when you lost it, and the finder does not enable it by some rare miracle, you will never find it.
Most probably you are screwed OP. I lost my SGS1 the same way.
You can however try sending to your number a text message that says "Get $$ reward for this phone, call XXXXX" or something similar, and hope the crook will decide to return your phone. For this to work the phone must only be on and must be on a cell network (no data required).
Last option is to print reward ads and stick them to light poles in the area where you lost the phone.

hmmm... And I thought my lost-phone-karma was positive, since I found and SGS1 a few months ago and returned it to the owner immediatly.
well, my only chance is, the phone will be connected to a wireless connection, since ive got my sim blocked through the provider. The hope is gone but who knows, miracles can happen
Firstly, good luck carthago, I hope you find your phone!
Secondly, and just for curiosity, does anyone know if could Samsung DIVE, Tektrak, Lookout and those similar tools can operate if the person who find the phone do a factory reset or flash a new firmware? I doubt that it could be possible, however I'm not an expert.
If there is no way for those tools to work after a factory reset or a flashing a new firmware, their usefulness is limited to the case that the thief either an idiot (regarding the factory reset) or computer illiterate (regarding re-flashing the phone).
In the case of free tools, any remote possibility of help is welcome, of course (better than nothing), however there are also many paid apps which purport to be THE solution this kind of problem.

All those tools are good IF you lost the phone, realized it right away, ran to the nearest computer and activated the tools, provided the phone is still reachable and on data network.
For the crooks who STEAL the expensive phones, the business is a fine tuned machine. 10 people run around stealing, and the immediately turn them off or remove battery. then they bulk-sell them to phone hackers who produce brand new freshly installed phones that can be sold at local flea market
Deactivating the IMEI I think will do anything only if the new owner tries to activate the phone on the same network.
First I was calling my phone again and again, cause I thought perhaps it was laying around somewhere and so I could hear it. But then that asshole had found out how to shut it down.
If you find something and theres no name and nothing on it, ok, if you keep that perhaps thats not exactly stealing. But if you shutdown a phone, because the owner is calling again and again, that is STEALING!

I was just wondering: one of the features of those tracking apps is the possibility of wiping your data if you lose your phone. Therefore, if wiping your data in this way (which I don't know if it corresponds to a factory reset or is just a 'soft wipe') means that it will be no longer possible to locate your phone?

[Q] Secure N7 from physical access

Hi,
I understand that if a person get physical access to the device, even if it is encrypted and password protected, access can be obtain by connecting the tablet to a computer.
This could be done even if the N7 is not rooted neither debugging mode is on and fast boot is locked.
Thanks.
Sent from my Nexus 7 using xda app-developers app
My concern is the following one:
The Nexus root kit allow to make a back up of the device, to unlock fast boot (That step will wipe the device), root the N7.
I understand that these steps can be done without N7 password.
When access in root mode, malicious code could be installed.
Nexus root kit allow you to restore the backup previously done, unroot and re-lock fast boot.
If what I state is correct, a person with physical access to the device can do whatever he wants to do. The user will have no way to be aware of it.
There is a way to protect a N7 against that kind of attack?
There is a way to protect access to fast boot or to disable access through USB?
Sent from my Nexus 7 using xda app-developers app
The way I understand it, I may be wrong though.
If you keep the boot loader locked, a malicious person would inevitably have to erase everything on the device to unlock it to root it.
Now if they made a backup first using the tool kit and restored when they were done, I feel they may undo everything they tried to put on your device.
Granted they would have a complete backup of your device on hand after everything's said and done
If physical security is a concern, I'd suggest having your information you want to keep safe completely off the device, using a cloud service, and inputting your password into such apps all the time.
Sent from my Nexus 7 using xda app-developers app
If I turn on pattern lock (haven't tested with pin, password, face, but I don't know why it would be any different), and connect N7 to the computer, it won't connect. As in, I still see the Nexus 7 device in my computer, but when I click on it, it displays nothing. Only once I enter the pattern, files appear.
Of course, once you enter the pattern, you will gain access to files, even if you relock it (while still connected - once you disconnect, you will have to reenter the pattern)
You can encrypt the tablet in Security settings, and while I don't really know what that does, it should make the backup file unreadable without a password, otherwise this feature is useless.
And I think if you disable USB debugging, you can make installing ROMs and stuff not very possible (but I'm not sure - I just assume, since every flashing tutorial starts with 'enable USB debugging')

Thanks for your response.
Sorry I miss explain the chronology:
The attacker switch off the device (could be done even if screen locked)
Reboot to the boot loader
Make the back up with the Nexus Root Kit. --> No password required, correct?
Unlock boot loader --> Device wiped.
Root the device
Restore the backup
Include malicious code
Unroot
Re-lock
If any one can confirm what stated is correct and if there is a way to prevent it.

Honestly, what are you afraid of happening? What do you keep on your device that would make someone go to the trouble to do this? They wouldn't even be able to boot into the OS if it was encrypted. The encryption is your best bet. Or, just don't let the device out of your sight (or pocket).

We need to secure several N7 that will be use by top management. We choose the N7 because no physical ports (unless the USB...). The back of the device will be glued, we will use a tailored version of Android (no google services at all) plus VPN for all data connection but we still get the physical access flaw issue.

Hmm... In that case, you might just have to secure it physically. The only way to prevent the exploit you mentioned would be to develop a custom bootloader that doesn't allow fastboot without proper authentication. But that's unrealistic.

In that case you might look into well, a case with a lock to block the USB or maybe some other hardware hacks that impede the device from connecting to a computer.
A case with charge ports to the pogo pins that obstruct the USB might be an option.
But like what was said, i custom boot loader might be a better option, contact Google directly about how to block boot loader unlocks
Super glue the usb port and charge through pogo pins

[Q] I lost my Nexus - what now?

HI all, I lost my Nexus 7 today.
I was gutted - searched high & low in the local supermarket and couldn't find it.
Luckily a decent chap had found that his nephew was sat in the car playing with it (having found it) and I got it back. (cheers chappy!) :good:
I am still in shock about this, its my 3rd arm, my memory, my precious!
However - what in case this happens again?
I have Prey on it, but I have found that there is some delay when the alarm goes off and it being locked - long enough for me to find and stop prey.
I have lookout security on it.
So I can get a location and a photo, lock it (assuming the person with it is not techy and turns both off first.)
Can you recommend any other apps etc?
I think a big sticker inside my cover with my details might also be in order.
What would you suggest?

Order an iron cage and then hook that cage to yourself and make sure when you are not using it, it must be kept inside.
You will never lose it!
Great words from Alfred lord Tennyson: Tis better to have lived and lost than to never have lived at all.
On s serious not, I think cerebus is good. If you're rooted it can be a system app and even survive a factory reset. Not a factory flash though. Most people won't know how to though.

I use it too, but you'd need to have / hope your tablet will hook onto a wifi network if you want recovery options. Otherwise, you'll have to hope Android's security options will protect your data if you consider it sensitive.

EDIT:AH! maybe the update to 4.3 unrooted it?
What would worry me most is
My home was ripped off and all they took were iPads. I at the time did not use any code to create security so I knew my iPad was gone forever. The thing that bothers me the most about your story is how some kid found your device and didn't tell anyone, just taking it out to his car and playing with it, intending to keep it of course,.
Two things about these 7" tablets. They are easy to carry along and easy to misplace so it behooves one to always have a place for it and always use security so it can't just be used without at least making an effort.
Yes that is a worry - I might have to start using a pattern lock or something.
Cerberus looks cool - but not all the features work - I think 'll neet to root it again for that.
Its cheap too - might go for it.
Oh and the android device manager is OK too.
Not sure if I should start another thread on this - but now that I have upgraded to 4.3 and its no longer rooted, will running wugfresh and re rooting it remove any apps or data on it?

If the tablet is still unlocked (i.e., unlocked padlock symbol under "Google" logo while it boots up) then all you should need to do is flash the SuperSu zip file that can be found in many places on this forum to root, and a factory reset shouldn't be necessary, but always make a Nandroid backup just in case.
If you need to unlock the bootloader (necessary to root), last I checked a factory wipe is required.
Cheers, its backing up right now.

I have purchased cerberus, it was cheap enough and does the job.
After several backups using the nexus toolkit etc I have used cerberus to see if it can wipe it.
It did.
Not sure whether to smile or frown lol.
Now I'm restoring, however I notice that my folders are not restored, just the apps so I have to sort everything again.
But it did the job, I wont use a pattern lock so if its lost the finder can either try to contact me or use it online - and thats needed to be able to take pics and locate it etc.
I think I'll look into the adding of cerberus to the rom also, also going to add the wifes phone & tablet to my account.
Oh hang on - restore has just finished.
Hmm - not happy - fast notepad does not have its notes
good job I did my own backup lol put em back now.

+1 on Cerberus, and you don't need root for most of it's features.
Are Cerberus photos working for you guys? For me they come out as vertical streaks, regardless of the photo format selected. This seems to be a common problem, as far as I can tell.
Photos are working fine for me however I would note a few issues.
It does not always communicate well, wiping required root.
If the wifi is off then I need to wait until someone turns it on, so I cannot use a pattern lock on it.
If I send a siren message then they can instantly cancel it.
Mine is in a Lente Designs case with a magnetic cover so it auto locks it when closed.
However, the siren just goes "Brpp" with the cover closed, open the cover and it goes off, close the cover and it stops.
And the lock - if II enter the correct code the next time it sleeps I then need to enter the lock again.
So you need to send an unlock command to it to stop this.
All the same I bought it and installed it on my tablet, wifes tablet & phone.
I suppose at the very least I can find her when out shopping lol
+1 for Cerbus. I have it on 3 devices.

If you are rooted, I would do a nice backup and start fresh (factory reset).
Random bits of leftover data are usually what cause little annoying bugs like that. Also for the battery, use a wake lock app to see if any app/service is constantly waking up the device, and not letting it sleep

Hmm.. So you updated over WiFi? Like the ota? Since you have already reset, I would flash the phone stock 4.3 using either a toolkit you find here, or through fastboot if you have the know-how.
Because doing a wipe clears data, but if there is a problem with the actual system files you need to reflash it
