QuadRooter Scanner: is your Android phone vulnerable

QuadRooter Scanner is a new application for Android devices that scans a device and tells you whether it is affected by the recently disclosed QuadRooter vulnerability.

QuadRooter is a set of four vulnerabilities affecting Android devices using Qualcomm chipsets. Disclosed on the Check Point web blog on August 7, 2016, the vulnerability is said to affect close to 900 million Android devices that are in circulation currently.

Attackers may exploit the vulnerability using specifically prepared applications. The app would not need special permissions according to the researchers, and could give attackers complete control over an Android device.

If exploited, QuadRooter vulnerabilities can give attackers complete control of devices and unrestricted access to sensitive personal and enterprise data on them. Access could also provide an attacker with capabilities such as keylogging, GPS tracking, and recording video and audio.

The researchers released a short list of affected devices that reads like the who is who of the Android world. Included are the Google Nexus 5X and 6, the new Moto X, The OnePlus One, 2 and 3, the Samsung Galaxy S7 and S7 Edge, The Sony Xperia U Ultra, the LG G5 and G5, and various other devices.

The list is incomplete however, and there was no way of telling up until recently whether a particular device not listed is affected by one of the four vulnerabilities.

QuadRooter Scanner

QuadRooter Scanner changes that. It is a free application for Android devices that scans the device it is run on to find out whether it is vulnerable to one, some or all of the four vulnerabilities discovered recently.

All it takes is to tap on the scan button after you have installed the app to run the scan. It takes less than a minute to complete, and will list whether the device is vulnerable to some of the vulnerabilities discovered.

Links are provided to the vulnerabilities the device is affected by which may be useful when researching the vulnerabilities.

There is little that you may do however if the device is affected. While you may be more careful than usual, by not installing any apps from outside the Google Play store, and even then making sure it is created by a legitimate company, there is no direct option available to protect the device fully.

It is up to the device manufacturer to release a timely patch for the vulnerabilities the device is affected by. The past has shown that it will take some time before even the companies that care the most push out patches. For some devices, patches may never be created and there is nothing that users can do about it other than switching devices (preferably from a company with a better track record).

Now You: Is your phone vulnerable?

    2G?

    Where on the planet is that still in use? I was forced to give up using my RAZRV3 years ago because 2G was phased out by AT&T.

      Everywhere 3G has been turned off and you don’t have LTE coverage, and believe me there are many developed countries where this is the case and if it weren’t for 2G you wouldn’t even be able to make a phone call.

      Maybe I missed it, but I don’t believe tha term “2G” is in the article. Perhaps you are referring to “AGM G2”??

    Your website has gone insane.

    When I the post button I then saw my comment posted on a different article page. When I opened this article again, it is here.

        @Tachy,
        @Martin P.,

        For over two weeks now,
        I’ve been seeing “Comments” posted by subscribers appearing in different, unrelated articles.

        https://www.ghacks.net/windows-11-update-stuck-fixed-for-good/#comment-4572951
        For the time being,
        it would be better to specify the “article name and URL” at the beginning of the post.

    @tachy a lot of non-phone devices with a sim in them rely on 2G, at least here in europe.
    Usually things reporting usage or errors/alarms on something remote that does not get day to day inspection in person. They are out there in vast numbers doing important work. Reliable, good range. The low datarate is no problem at all in those cases.
    3G is gone or on its last legs everywhere, but this stuff still has too much use to cancel.

    Anyhow, interesting that they would put that in. I can see the point if you suspect a hostile 2G environment (amateur eavesdroppers with laptop, ranging up to professional grade MITM fake towers while “strangely” not getting the stronger crypto voip 4G because it is being jammed, and back down to something as old ‘stingray’ devices fallen into the wrong hands).

    But does this also mean that they have handled and rolled out a fix for that nasty 4G ‘pwn by broadcast’ problem you reported earlier this year? I had 4G disabled due to that, on the off chance that some of the local criminals would buy some cheap chinese gear, download a working exploit and probe every phone in range all over town in the hope of getting into phones of the police.

    >”While most may never be attacked in stingrays, it is still recommended to disable 2G cellular connections, especially since it does not have any downsides.”

    The downside would be losing connectivity. I spend a lot of time way out in the countryside where there’s often no service or almost none. My network allows 2G, and I need it sometimes. I have an option on the phone to disable 2G, I may do that when I’m in the city and I have good 5G connectivity, but not out in the country.

    I would imagine that the stingray exploits, like most of the bad things in this world, are probably things you will run into in the crowded big cities.

    I stopped using it in a mobile (Wi-Fi line) environment, so I’m almost ignorant of the actual situation,
    But the recent reality in Japan makes me realize that “the infrastructure of the web is nothing more than a papier-mâché fiction”.

    It is already beyond the scope of what an individual can do.
    What we should be aware of is the reality that “governments and those in power want to control the world through the Web”, and efforts to counter (resist and prevent) such ambitions are necessary.

    Why do you want people to disable the privacy features? Hmmmmm?

    Now You: do you plan to keep the Ads privacy features enabled?

    I’d like to tell you, but apparently if you make a post critical of Google, you get censored. * [Editor: removed, just try to bring your opinion across without attacking anyone]

    The comments are seriously messed up on gHacks now. These comments are mixed with the article at the below URL.

    https://www.ghacks.net/2023/08/18/android-how-to-disable-2g-cellular-connections-to-improve-security/

    And comments on other articles are from as far back as 2010.

    How about other things that matter:
    Drop survival?
    Screen toughness?
    Degree of water and dust protection?
