Android malware perspective: only 0.5% comes from the Play Store

Are Android apps secure enough for us to let them handle our finances and personal information? Quite a few of them aren't, according to a recent research that analyzed how well various applications protect the user's sensitive data. The study was conducted by the Leibniz University of Hannover, Germany, in partnership with the Philipps University of Marburg, the researchers came up with a list of 41 Android apps that should use tighter security measures.

In particular, these apps were discovered to expose the user's data at risk while a device running Android 4.0 is communicating with a web server. What's even more worrying is that these insecure apps were among the most popular ones on Google Play, being downloaded between 39.5 million and 185 million times already. The names of the applications were not disclosed.

"We could gather bank account information, payment credentials for PayPal, American Express and others," the researchers wrote after conducting their study. "Furthermore, Facebook, email and cloud storage credentials and messages were leaked, access to IP cameras was gained and control channels for apps and remote servers could be subverted." The contents of e-mails and instant messages could also be accessed.

But how could one use these apps' security flaws to their advantage? Simply put, if an Android smartphone or a tablet is connected to a vulnerable local area network, such as a Wi-Fi hotspot, an attacker could potentially crack the security protocols used by the apps and snoop on the data they exchange. Sure, the attacker will need to have a certain exploit monitoring the activity on the network, but obtaining access to such a tool isn't as hard as it may seem.

Scary stuff, we know, which is why there should be more awareness amongst developers about implementing proper security features within apps, as the researchers suggest. There are certain methods that can make security protocols tougher to crack, or the apps could simply be checked for vulnerabilities at the time they are being installed. In fact, Google is said to have ramped up security in Android 4.2, thus likely making the platform more resistant to hacks like the one described above. What measures have been taken, however, will be known with certainty in a few days – On October 29, to be more specific, which is when a new Android release is probably going to be unveiled.

Over 60% of Android malware steals your money via premium SMS, hides in fake forms of popular apps

Over 60% of Android malware steals your money via premium SMS, hides in fake forms of popular apps

Like any popular platform, Android has malware. Google’s mobile operating system is relatively new, however, so the problem is still taking form. In fact, it turns out that the larger majority of threats on Android come from a single malware family: Android.FakeInstaller, also known as OpFake, which generates revenue by silently sending expensive text messages in the background.

McAfee says that the malware family makes up more than 60 percent of Android samples the company processes. So now the question is: why is this malware so popular amongst cybercriminals?

The reason is simple: it’s extremely effective. Android users seem to fall for fake apps on a regular basis. Furthermore, since the whole of the malware appears to make money, it’s not surprising that those behind this one continue to keep it updated. McAfee agrees:

Malware authors appear to make lots of money with this type of fraud, so they are determined to continue improving their infrastructure, code, and techniques to try to avoid antivirus software. It’s an ongoing struggle, but we are constantly working to keep up with their advances.

This malware type has been in the news for months, mainly because there have been so many fake apps created, including for popular ones like Instagram and Skype. On top of that, those behind it seem to keep adding various types of functionality to avoid detection by antimalware solutions, including server-side polymorphism, obfuscation, antireversing techniques, and frequent recompilation.

How it works

Cybercriminals typically create fake versions of a given popular Android app to earn money from unsuspecting users. There have also been instances of the malware being bundled with a legitimate version of popular apps. The apps appear to be legitimate, including screenshots, descriptions, user reviews, videos, and so on. Users never get the app they want, but instead get a lot more than they bargained for.

The malware authors often set up fake websites advertising the fake version of the app. Many of these are shared on questionable websites, but many are also shared on fake Facebook and Twitter accounts that spam legitimate users on social networks.

Upon installation, the malware often displays a service agreement that tells the user that one or more SMS messages will be sent. The user is forced to click an Agree or Next button, but some versions send the messages before the victim even taps the button. There are often fake progress bars to keep the user further in the dark.

Either way, the devil is in the details. In the background, the malicious app sends expensive international text messages to earn its creators revenue. Some variants even connect to a Command & Control (C&C) server to send and retrieve data, as well as await further instructions.

Early versions of FakeInstaller were created only for Eastern European users, but malware developers have expanded their fraud to other countries by adding instructions to get the device’s Mobile Country Code and Mobile Network Code. Based on that information, the malware selects a corresponding premium-rate numbers.

How to protect yourself

The good news here is that since this malware family is so prevalent, it’s rather easy to avoid it: just don’t download fake apps. Android lets you download and install apps from anywhere, but unless you know what you’re doing, you shouldn’t be installing anything and everything you can on your phone or tablet.

If you want to significantly reduce your chance of getting malware such as this one, only install apps from the official Google Play store. That being said, malware has snuck into the store before, so it can happen again.

As a result, the way to protect yourself is the same as on any other platform: don’t click on questionable links and don’t download random apps. Always check to see if what you’re getting is legitimate and you should be fine.

Android’s malware problem is getting worse, and only users of the latest version are safe from harm

Earlier this year, we saw a report that said there was a 163% rise in the number of malware-infected Android devices in 2012. As shocking as that figure might be, we have a new report now that says the problem has blown up even further.

According to a recently published report[1] from networking vendor Juniper Networks, the number of mobile threats grew an astonishing 614% from March 2012 to March 2013. This equates to a grand total of 276,259 malicious samples, according to research done by the company's Mobile Threat Center or MTC.

What exactly constitutes such a large amount of mobile threats? It is said that the majority of these mobile threats — 77% of the total — come in the form of money-siphoning applications that either force users to send SMS messages to so-called premium-rate numbers or somehow manage to perform the sending of SMS messages all on their own.

They go virtually undetected as they are normally bundled with pirated apps and appear as normal applications. Typically, these malicious apps can net their creators an average profit of about $10 per user, according to Juniper Networks.

As it is currently the most popular mobile device platform in the world, it's easy to see why Android would be targeted with such malicious activities. But perhaps you're wondering, is there anything that can be done to combat this problem?

ndeed, there is. In Android 4.2 Jelly Bean, a new safety feature was introduced in order to stop wayward SMS messages dead in their tracks. But that in itself is a huge problem: Android 4.2, the latest version of the Google mobile operating system, is only available on a tiny fraction of all Android-powered devices out on the market. In fact, many of today's newer devices don't even ship with it. So the relevant safety features, as useful as they might be, becomes pretty much useless.

Even worse, the money-making malware mentioned above represents only one type of mobile threat on Android. Android spyware is also present, accounting for 19% of the total malicious samples collected in the above-mentioned research. These could potentially put a user's privacy at risk, collecting sensitive data and all kinds of information then relaying them to the spyware's creator.

Trojan apps have also been discovered to be part of the overall Android ecosystem. Although they form a very small part of the entire body of mobile threats on Android right now, it is possible for them to become more widespread in the future. If the fix really only lies in having the latest version of Android installed on a device, and the issue of fragmentation — not to mention the slow software updates from carriers and OEMs — persists, that's almost a certainty.

What do you think could be done to finally overcome these kinds of problems? Will it be the end of Android as we know it? Let us hear your thoughts in the comments.

Mobile malware getting out of control? Study claims 614% increase on year, Android accounts for 92% of total infections

A terrifying report was released two days ago by the Mobile Threat Center arm (MTC) of Juniper Networks – a manufacturer of network equipment with a hefty stake in enterprise security. According to Juniper, its MTC research facility is dedicated to 'around-the-clock mobile security and privacy research'. The MTC found mobile malware growing exponentially at an alarming rate – a 614% on year increase reaching a total of just about 280,000 malicious apps.

A major app vulnerability has been found which can be effect 99 percent of the Android smartphones on the planet.​

A major app vulnerability has been found which can be effect 99 percent of the Android smartphones on the planet. The issue was unraveled by Bluebox security, which claimed to have found an ‘Android Master Key’ that could allow a hacker to turn any Android app into a malicious zombie.

This basically means that an app could allow hackers to capture data and control a device remotely, without the owner and the app developer knowing about it.

And the kicker is that, this is not a new vulnerability as Bluebox has discovered that it has existed since Android 1.6 Donut, which is four years old.

Jeff Forristal, CTO of Bluebox securities revealed that his company had found a way where in a hacker could possibly load an app with malware and still make it appear to be a legitimate file. This bit is important because verified apps are granted full access by default on the Android system.

However, on the bright side apps on the Google Play store are impervious to this problem, so if one sticks to downloading apps from the Play store then one is in the clear. That said, there are a number of third party app stores and users can even download APKs directly off the web and here’s where the danger lies as it is possible for users to download tampered apps.

This problem is accentuated more in countries like China where users like to use local app store over the Google Play store and many OEMs like Xiaomi don’t even bundle the Google Play store on the device by default.

Bluebox securities claims that it reported the problem to Google way back in February and the issue has already been resolved for the Galaxy S4 and currently Google is taking a look at the Nexus range of hardware.

Cryptographic bug in Android lets hackers create malicious apps with system access​

Security researchers have found a bug in Android which allows them to create malicious Android apps which appear to be genuine with the correct digital signatures. In computing, digital signatures allow any piece of data, including an app, to be checked to see that it is genuine and actually comes from the author. Now, due to a bug in Android, it is possible to create a fake app and sign it so it looks like a real app from any author including Google, or others like Samsung, HTC and Sony.

Since the digital signatures of Google and handset manufacturers can be faked it is possible to create a low level system app which has absolute access to the device. These system apps, which have what is known as 'System UID access' can perform any function on the phone including modifying system-level software and system-level parameters.

If such an app is installed on an Android phone, the user would be completely vulnerable to a multitude of attacks including key-logging and password sniffing. The researchers at Bluebox Security informed Google about the flaw (Android security bug 8219321) back in February and are now planning to reveal details of the bug at an upcoming security conference.
