[Security Discussion] Raoa:
Introduction

I have not seen much talk about security in XDA, and not at all on Neo Section.

SO here's just one informative link talking about using and developing apps and security risks involved

http://www.technologyreview.com/computing/25921/?mod=related

Any bug in software could potentially be used as a security loophole to gain access to private information, spy on you, get your credit card info(should you do such things on phone).

What is kind of unsettling is that everyone seems fine with modding, tweaking, developing and using those ROMs made in XDA without worrying if there could be that kind of bug in your made or used ROM.

You don't need a malicious app only to have risks. Most people use Windows so they should know that it is OP systems bugs and vulnerabilities that allow for unwanted access to your files, data, etc.

Android itself is having very non-foolproof security system. All apps on unrooted phone are in sandbox. That's no security measure at all. It doesn't limit app from stealing your private info at all, it only cant delete the whole ROM. That's just idiotic security system, for it is the only thing beside encrypting shut off phone on 3.0 and 4.0. So that means Android on it's own has no security measures while it's working. Even Windows has... some... but not too much... so you could pay for antivirus and antispyware software ofc.

It has always been the goal of big corporations to make money from insecurity, be they software developers, arms dealers and you name it. They all benefit from insecurities existing. Same is with Google and it's Android. But the good news is that we the users can modify Android. We could all say "Au revoir security bugs and loopholes!" if we would care about developing ROMs designed to make Android more secure... alas that's not happening yet!

Overview of Linux/Android security issues.

It's a short condensed description just to get you interested in the topic. There's lots of material on net, you only need to search, read, watch videos.

Linux becomes more vulnerable with more applications with different permissions installed. Same is true for Android.

Say your Phone Exporer has root access, that means it has root access to whole Android. To remove unnecessary risks, this app's root access should be limited to only most necessary functions it needs to operate.

Currently for Android there is no such solution. For Linux there is Apparmor.

http://en.wikipedia.org/wiki/AppArmor

Total root access is obvious vulnerability, but it is at least known one. Let's look at possibility of apps having hidden permissions and what that could mean to you.

Blade Buddy from Market.

On market it does not list permission to "Unique Device ID"(IMEI for GSM and MEID; ESN for CDMA) for free nor for paid version.

That means the author of BB has left the code from free version in paid one. This permission is used by ads to track you. It's not necessary code for ads, but it helps the dev know who clicked on the add and generated him some money. To see your money generating zombie empire stretch across the whole globe.... quite a thrill, isn't it?

So it's a latent code, with no benefit to user and an exploit only calling to be abused.

Unique Device ID allows you to be tracked on net and also where you are physically. GPS is just one way to find you, police for example have scanners to locate your devices physical location by the IMEI code. You can count on the "bad guys" having this technology as well, for it's quite a tool for burglars and other criminals.

The risks of your home being marked as the next dungeon to be looted by some raiders, I mean criminals(or perhaps WoW players sleepwalking and sleepraiding?) or getting your ID and bank details stolen by trojan/hacker is random. Yet the threat would not exist without apps having so flagrant hidden permissions.

Next app with ludicrous permissions

Brightest Flashlight

It does list many permissions, among them "Hardware controls - take pictures and videos ". No, it does not need a permission to take photos through cameras to operate the flashlight. But it's fun nonetheless for the dev to see his trusty peasants, or maybe he just likes to observe people like some watch fish in aquarium or hamsters in cage( "Look at that dork!", "You're one ugly m...f...er","ummm a couple kissing in dark with ma flashlight, what are they searching?", "what's that you eat, mr Korean, brains?" "hey show me that document again.")

You don't even need to run the app yourself. It can be triggered by hacker on background and take a snapshot of you.

On top of this little needless permission it has following hidden permissions:

1. Unique IMSI, read about here http://en.wikipedia.org/wiki/IMSI

2. MCC+MNC (CDMA)

3. Unique Devide ID

4. Cell Tower Name.

That's a lot of needless permissions for flashlight, these are there just to track you the app user and have nothing to do with your comfortable use of the app.

These are just 2 apps with totally needless permissions for their intended functioning. If you don't want your Windows and Linux have such security holes then why do you want your Android have them?! You don't want, that's the point and these apps would not be so popular if people would really know and care about their phone being secure.

It can be stated for sure that above exemplified permissions not listed on market are more useful for pranksters, criminals or someone plainly looking-down-on-all-the-dumb-sheep and not at all for any legitimate, user or customer friendly purposes.

There are very few tools to check for security and privacy problems in apps. That gives a sense that majority of devs do not want Android to be secure and private, because Android is another revenue generating platform through Google ads business of course. Were people more educated about the matter then Google ads business would shrink down as well. A private and secure Android can't be tracked or annoyed with ads. No ads, no profit. No security therefore means profit. Unfortunately this lack of security can be exploited by anyone with criminal or malignant intentions so very easily.
