New SMS Trojan Found In Android Markets

Trailrunner7 writes "The Android platform seems to have become the playground of choice for attackers and malware authors looking to make a quick buck. The latest example is a premium-rate SMS Trojan that not only automatically sends costly SMS messages, but also prevents users' carriers from notifying them of the new charges. The new piece of malware, which is known as HippoSMS, has been found in unofficial Android app markets in China. This is just the latest in a series of similar incidents in which attackers and scammers have inserted either outright malicious apps or seemingly benign apps containing malware into app markets. Most of the attacks have targeted Android users, and several times Google has had to remove malicious apps from the official Android market."

    Why don't these articles ever tell you WHICH markets and apps are affected? Oh, that's right, they're too busy trying to generate page hits through scare-mongering to care about information.

    (I'm not trying to say these aren't legitimate threats: quite the opposite. But, good reporting would help mitigate these threats by publicly shaming and informing.)

      No, that's the name of the malware, not the apps. FTFA:

      "The malware is embedded in a seemingly legitimate application in the market, and once users download and install that app, the fun begins."

      It goes on to talk about "the host app" which the malware "piggybacks". Which app? They don't tell you. They'd rather tell you that "The Apple iPhone may still be the gold standard when it comes to smartphones".

    If you want the freedom to install whatever you want from wherever you want, you have to accept that some of those things may not be good for you or your devices. To me, it's worth the trade off.

    In the end, the best protection will always be common sense. To those that do not feel they possess enough knowledge to make their own decisions in this regard, there is always Apple who will gladly make the decision for you. To each their own.

    As someone who is about to get their first Android device, is there a good resource for practices for protecting it?

    Reading the summary, it seems this is a 3rd party market that was infeted. Obviously the first thing is not to install everything you see, followed by don't use 3rd party markets. However there seem to be several 3rd party markets that do have worthwhile software. Is there a suggested list of marketplaces that are reliable?

    There also appear to be several Android firewall apps. Is there a site where they are reviewed and compared?

      A good practice is to find an app in which you are interested, then review the permissions to verify they make sense.

      For instance, if you're downloading a new phonebook and the app asks for permission to your contacts, you can assume that it really needs it.
      If you're downloading a new tic-tac-toe game that asks for full permission to read your ingoing and outgoing calls, you should really question why it needs that.

      This isn't foolproof, but it is a really good place to start.

      I'm pretty technical but I find the permissions too vague. they are still mostly 'opaque' and I have little actual idea what's going on.

      maybe if they showed some of the data they GET, as an illustration? maybe they cache some of the 'captured' data the app 'takes' and show you that, on demand? that way I can say 'oh, you mean you're grabbing THAT from me! fuck you! delete.'

      if there's no examples of the data they take, conceptual permissions just don't work for users. works for programmers who have the code. this is NOT the users, though! not even tech ones. no one has time to audit every program in your phone.

      You may want to read this earlier Slashdot story, from which the suggestion that made the most sense to me was to install DroidWall and just not let applications access the network. Of course, they might not work then, and it can be difficult to single out a single app among, say, Google Services.

      Uggh ... terrible moderation here. This is flamebait, not insightful. As an ios developer, I recommend that you buy the device that best caters to your needs and if you do get off the beaten path with that device -- educate yourself on possible dangers. If you install 3rd apps on your android device, check its requested permissions. If you root your ios device, change the freakin' root password. The issue isn't the device, but the person using it.

      Seriously ... I'm tired of this android / ios pissing match on Slashdot -- and that includes mods. I know it generate hits but it's make for terrible conversations. Believe it or not, they can co-exist.

    I can agree that appliances should be restricted in their functionality. My current phone doesn't have "apps", it just handles calls and SMS, and I like it that way.

    Well, that brings us neatly around to my original point: If you have the freedom to install apps from anywhere, you have the freedom to install malware. This freedom does not come with what should be the prerequisite dependencies of common sense nor investigative abilities. So in essence, you now have the freedom to hurt yourself, alongside the freedom to do anything you want. You can't have one without the other.

    There's certainly legitimate uses for the 3rd party app stores still, such as google has to remove emulators and such to avoid getting their asses sued into oblivion. I do have to say though I am not even slightly concerned about the infected apps from obscure chinese marketplaces, but I do think there is legitimate concern about the ones that have slipped into the marketplace. I do think google needs to step up and add a few layers of QC to the official marketplace. The best of both worlds scenario would be a fairly well audited for quality of apps official market place, or even maybe a certain sticker of "Google approved" applications, something simply to confirm that things are absolutely safe, for the average non-techie user, just as long as there are no warantee voiding/risking hurdles added for fairly competent users to get the unverified apps that they may want.

    There was a proof of concept that could execute arbitrary code on iphone by sending about 500 SMS and which worked about 20% of the time, as explained by the hacker here. Of course serious bugs aren't really news on either platform. There was a time when Android would execute all text typed into the phone as root, then there was the Android bug that sent your messages to random contacts or the one where an SMS corrupts Androids SQLite database. People in glass houses should throw stones you know.
