Beware of Fake Adobe Flash Apps


By Joe McManus

Last week Adobe announced that they would no longer be supporting Flash for Android. Adobe will be removing Flash from the Android Marketplace and users should be wary of fake Flash apps for their Android Devices.  Now to be fair to Adobe, they are not taking flash away from the Android platform but are focusing on the Adobe AIR cross platform runtime environment http://www.adobe.com/products/air.html. The reason Adobe is switching to AIR is to allow app developers to write one program for use on iOS and Android devices.

Let’s look at some of the fake Flash apps for Android that we have seen and what they do. This is just a small sampling; there are too many to highlight them all.

This first app we’ll look at is one of hundreds of premium SMS Trojans being distributed on third party markets that are fake installers for legitimate applications. What they really do is charge for what may or may not be a download of an already free app. The scam works when the user agrees to their ‘Terms’ and the app will send out three SMS messages containing SMS short codes that come with a fee. These messages go to a premium service setup by the malware author and will appear as charges on you phone bill. The charges vary depending on the user’s location but range around $8-12.

This has appeared many times as Flash Player 11, Flash Payer 10, FlashPlayer, etc. Webroot detects them as Android.FakeInst and has been tracking these type of fake installer for over a year; here, here and here.

Our next example is another scam of sorts. It doesn’t charge for anything but will install a bunch of aggressive advertising SDKs that are known to create ad-related notifications, shortcuts and bookmarks. This app requests 24 Android OS and device-specific permissions when, at most, it would need the INTERNET and WRITE_EXTERNAL_STORAGE permissions. The additional 22 permissions are for the ad SDKs. Webroot detects one of the ad SDKs bundled with the app as a Potentially Unwanted Application (PUA) and labels it  Android.Ads.Plankton.B.

Although it does download Adobe Flash for Android after agreeing to their License Agreement it does come with the cost of a bunch of other non-flash related stuff.

This final example is for an app that claims to be Flash Player but really installs an Adobe Flash Icon, that merely opens a browser window full of advertisements. These types of apps are annoying and really are meant to drive web traffic to sites so the developer can receive pay-per-click revenue, and in this case they deceive the customer into thinking they’re getting a known productive app. Like the previous example, this app isn’t malicious, but it’s more deceptive and doesn’t deliver on what it claims, for that Webroot detects Android.DreamStepFlash as a PUA.

Malicious and untrustworthy apps come in many different flavors, and as you can see, Adobe Flash is one that is used to lure unsuspecting users to install. Adobe will continue to release security updates for Adobe Flash and suggests you uninstall if your device is able to upgrade to Android 4.1.

Remember, always choose your apps wisely and download from a trusted source. Check reviews, research the developer and verify permissions requested before downloading.

“You Want To Pay For What!?”


by Nathan Collier

Recently we found new apps in alternative Chinese markets that we are considering a Potentially Unwanted Application (PUA).  We are calling these apps Android.PUA.SMS.QuickPay.  Lets look at a sample of this app.  The sample we will look at is an app called “Screen Detection” which is an app that helps find dead pixels on your screen by displaying the colors red, green, blue, black, and white making it easy to see the dead pixel in contrast to these colors.  Pretty simple app.  Within a few seconds of opening the app this message pops up:

“Activate the full version, charges 2 Yuan, sending an SMS, 2 /. Customer Service Phone :010 -84681340-8035”

This app has limited functionality before requesting a premium SMS be sent for the full version, and that limited functionality only lasts a few seconds.  If you do not agree to sending the premium SMS the app will just keep asking you to activate the full version whenever you click.  Once you agree to the message it turns on your Wifi if not already on (Okay, that’s a little fishy), and sends a premium text message.  After that the app works.  Two Yuan is about 32 US cents, so people may just pay the small fee instead of spending the time to find a free version; which with a simple app that only shows four different colors as it’s functionality you would think there is something out there in the Chinese android market that will do the same for free.

It may not seem like much, but two Yuan at a time these guys are making a fortune off of apps that should be free.  This is only one sample, there are several more very simple apps that we found that do various things, but all ask for a payment for it to function.  Although there are legitimate Android Box apps out there, these apps are different in that they have very limited functionality, are signed by a different developer, and exploits simple apps that should be free by requesting payment for full versions before you even have a chance to see what it does.

Remember to always download from apps from a trusted source and be weary of messages asking to pay money for the full version so quick on the draw.

Rogue APKs continue to find new homes


by Armando Orozco

We’ve been tracking rogue premium-sms Android apps for sometime now. Here’s an interesting site we came across offering a download of the Google Music application, but this one comes with a cost. This site serves up a premium-sms Trojan of the ransom variety. Targeting Russian speakers these Rogue’s, we call Android.FakeInst, offer to give access to the app but for a fee.

Reflections on mobile security


By Armando Orozco

Be wary the next time you enter your passcode into your iPhone on the bus – someone could be shoulder surfing. In fact, a team of researchers from the University of North Carolina has developed a system to watch you pecking out characters on your phone, analyse the video, and produce a pretty accurate guess of what you were typing.

When people talk about key loggers, they’re usually thinking about malware that sits on a computer and surreptitiously monitors what keys people are pressing. But these university researchers are applying an entirely different approach to key logging. Instead of putting software on computers, they are investigating ways to monitor the text that people input into their mobile phones. They do it by taking video of your phone, either directly (over your shoulder or from the side), or simply by reading the reflections of your phone’s screen in your glasses.

The researchers developed a mechanism for looking at mobile phone screens using cheap, mobile videocameras. The cameras record video of people typing on ‘soft’ keyboards, such as those used by Apple’s iPhone. These keyboards commonly use ‘pop out’ animations, in which the key being pressed gets bigger when pressed, to confirm to the user that they have selected the right letter. The pop-out animation makes it easier to see which keys are being pressed in the video.

Mobile cameras have increased dramatically in quality lately, making them far more capable of capturing reflected keyboard images. These cameras are embedded in smartphones, of course, or if you wanted to get even techier, you could buy one of these.

‘Tis the season for mobile malware


By Armando Orozco

You’ve heard of the “perfect storm”? Well, there may be one brewing in Android-land. We just wrapped up a study that revealed holiday shopping is about to go mobile—in a big way. Turns out, over two times more shoppers plan to buy gifts on their mobile device this year. Over two times more?! It got me thinking…

We know that Android malware is on the rise. Even Android users themselves seem aware of it; our mobile study also found that 23 percent more Android users are concerned with the security of their information than iOS users. And although Google reported it was tightening access to its open source Android OS back in March, our researchers continually spot plenty of opportunities to capitalize on vulnerabilities because there’s still virtually no review process for new apps

It’s not hard to put two and two together.

As sleigh bells start ringing and shoppers reach for their mobile devices, I can just imagine cybercriminals licking their lips. We’ve seen two popular tactics for Android malware: gaining remote access to your device’s data and sending texts to premium numbers. Of course the end goal is the same for both routes: money, money, money.  And what more profitable time to go after the pot of gold than during the busy gift-buying season?

But here’s one more thing to consider: We can’t single out Android devices, because malware isn’t the only risk. The portability of iOS-based smartphones and tablets means they can easily fall into the wrong person’s hands—and whatever data is on that device would go with it.

So before you hit the “mobile mall” on Black Friday, take a few simple steps to protect yourself and your data:

  • Lock your device. Most smartphones and tablets give you a choice of locking it with a password, numeric code or pattern.  Use it.
  • Know your apps. Only download apps from trusted sources, and never install apps that want to access functions they don’t need, like the ability to send SMS messages. And it’s always smart to check out reviews by users and the experts before installing.
  • Use caution when connecting to WiFi hotspots. Avoid banking, making purchases, or logging into secure websites when connecting to WiFi hotspots.
  • Install mobile security. Mobile security apps provide lost device protection, secure web browsing, and antimalware services. Webroot offers several free and premium versions of Webroot® SecureAnywhere™ for protecting devices on the iOS and Android operating systems.

The bottom line: Be a savvy shopper, whether you’re on your Android at the airport or your computer at home. ‘Tis the season to shop safely.

HTC acknowledges security flaw, plans update to fix


By Armando Orozco

A couple of days ago researchers for Android Police wrote about a security vulnerability in several HTC phones. The vulnerability lies with logging tools installed by HTC. These logging tools collect personal data like user accounts, email addresses, GPS info and SMS data. Having these tools logging users data is one thing but the fact that they are left unsecured and available to be exploited by a 3rd party app is a big blow to the device manufacturer. A 3rd party app would only need to request the INTERNET permission to gain access to the information collected by the tools. Why HTC has these tools in place hasn’t been answered, an answer they’ll have to provide to their customers at some point.

 
HTC’s public statement: “In our ongoing investigation into this recent claim, we have concluded that while this HTC software itself does no harm to customers data, there is a vulnerability that could potentially be exploited by a malicious third-party application. A third party malware app exploiting this or any other vulnerability would potentially be acting in violation of civil and criminal laws. So far, we have not learned of any customers being affected in this way and would like to prevent it by making sure all customers are aware of this potential vulnerability.”

 

The update will be sent over-the-air and users will receive a notification to install. No word on when the update will be available.

 
We all have a role to play in keeping our computing secure, but developers have a key role in that they need to ensure their applications are secure when it comes to customer’s data. This happens a lot, most recently with Skype, hopefully with more and more big name vendors being called out we’ll see developers tighten up their code.

The Big Picture for 2011 Security Trends

As 2010 winds down, I wanted to pull out the crystal ball and talk for a moment about where the security industry seems to be heading in the coming year, and where we anticipate threats and targets.

Mobile platforms: If you’re reading this, there’s a good chance you have either an iPhone, an Android phone, or a Blackberry in your pocket, case, or on your desk right now. If that’s true, then the data on that device is the next big target for criminals, and the newest front in the war on cybercrime. Users have embraced the advantages of mobile platforms, and even though IT admins may officially consider some or all of them “unsupported” in some organizations, you can’t abandon users who will choose convenience over strict IT policy. I predict that mobile platforms will continue to grow at a rapid pace, and we’ll soon reach the threshold level where malware creators start to take notice in significant numbers. IT admins should embrace these new platforms, and take steps to protect users who insist upon having them, even though doing so may make their work harder.

Social engineering: Whether you use a single PC at home, or manage a network of 25,000 laptops and desktops at work, social engineering scams have become so convincing that it’s a wonder IT admins ever get a good night’s rest.

It doesn’t matter how comprehensive your patch and update schedule is — when a sufficiently convincing spam email reaches a gullible employee, all bets are off. With targeted attacks becoming more common, the best defense against this threat continues to be education. Every user, from the newest administrative assistant to the C-level executives, needs training in identifying and avoiding fraudulent email and other messages, harmful file attachments, and Internet behavior that can lead to trouble.

Cloud vs. Desktop: We’ve seen demand for cloud-based services increasing across all segments of the business. In small and medium-sized businesses, we’re continuing to see strong demand for cloud-based solutions, and we expect that to continue next year. Overworked admins like the ease of administration and the performance benefits of cloud security services. And for the first time, we’re seeing consumers getting interested in the advantages the cloud brings to PC protection, including the speed that updates make it to the user of an infected computer.

At the larger end of the enterprise business segment, IT administrators must juggle the requirements of government regulations with the performance advantages that cloud services have to offer. In those cases where security regulations may not permit some kinds of data to move out into the wider Internet, we’ve seen a demand for what we call private cloud architecture — something that offers the performance benefits and features of a cloud solution, within an organization, while, at the same time, satisfying regulatory constraints on how companies move or store data.

We also can see how criminals have developed a taste for the vast volumes of sensitive data stored in the cloud, and anticipate that malware creators and other attackers will try to steal data stored in the cloud with increasing frequency.

Security Updates: More than 60 percent of malware attacks come from known vulnerabilities, so no matter whether you’re a one-person shop, or manage many thousands of desktops, maintaining not only the operating system but also the third party applications on which you (and your organization) depend should be a top priority. Besides office applications, attacks in the past year have focused on programs like Adobe Reader, Java, Flash, AutoCAD, media players, graphic design tools, and various browsers and browser plug-ins. IT departments should never let a new computer get to an employee that has anything older than the very latest build of these critical applications.

Consolidation: While not expressly a security trend, larger companies — some in the security space, and some that have not previously played there — have been augmenting their offerings. Intel’s purchase of McAfee, for example, appears to extend their platform beyond mere chipmaking. Other acquisitions, such as Webroot’s purchase of Brightcloud and Prevx, help companies acquire capabilities that can defend against, or remediate, a specific kind of threat. HP, IBM, and Symantec have done similar things, and with each acquisition, the companies gain another part of a toolkit they can use to respond to emerging threats. We expect to see more companies in this space merge and transform themselves over the next year.wordpress blog stats
