  1. Re:bug yes, and local access is full access on Many Android Users Susceptible To Plug-In Exploit -- And Many Of Them Have It · · Score: 1

    I don't believe you've understood Android's security model (though I'm not an expert myself). The local user cannot do those things, and the user does not have ultimate permission. Unless there is an exploit on the device. There have been plenty of devices that were un-rootable. My HTC One M7 was un-rootable (probably still is), unless you use HTC tools to perform operations on the device when it is not booted into Android. There was literally no way for the OS's local user to gain escalated permissions. If this new exploit changes that, it's not because "remote user == local user" or because "access to the device == complete pwned". You're simplifying it. This is only possible because TeamViewer is somehow running arbitrary commands with system permissions. Prior to this exploit, a local user could not do that.

  2. Re:"infinitesimal percentage of devices". For remo on Many Android Users Susceptible To Plug-In Exploit -- And Many Of Them Have It · · Score: 2

    If you install TeamViewer on Mac, people can take over your machine over the internet. That's what it's designed for. Therefore, from a security perspective TeamViewer is a very bad idea.

    It's no surprise that an application designed to give someone else full control of your machine is imperfect, and therefore can sometimes allow full access by someone who shouldn't have access.

    Wee difference there. On Android, nobody is supposed to get full control of the system. If someone is using TeamViewer to control it, they should not need more permissions than the local user has. After all, it's a screen sharing app. The remote user can only do what the local user can do.

    It seems like the app has additional permissions to do things that normally wouldn't be possible (screen capture is what the article mentions), but somehow these extra permissions are made available to one of the users. That must be the vulnerability.

  3. That is so cool on Many Android Users Susceptible To Plug-In Exploit -- And Many Of Them Have It · · Score: 4, Insightful

    > Check Point researchers found an app that is actively exploiting the vulnerability. A tool called “Recordable Activator” from UK-based Invisibility Ltd is advertised as an “EASY screen recorder” that doesn’t require root access to the device. But in fact once installed from the Google Play store, the app downloads a vulnerable version of the TeamViewer plug-in from another source... "“it’s [the plug-in] considered trusted by Android, and is granted system-level permissions. From this point ‘Recordable Activator’ exploits the authentication vulnerability and connects with the plug-in to record the device screen.”

    Am I the only one that thinks this is incredibly cool? It's not clear to me whether this is exactly the same thing as a root exploit, but some screen recording app developers figured out they could hijack an old version of a well-known app that can do screen recording. This is just a beautiful hack.

    But I didn't think having system-level permissions was enough to root a device. And furthermore, does this hack let you do arbitrary actions, or only the actions that the plugin would do?

    But I gather the scene is still one file, mostly? I mean, it's easy to edit assets separately, but the summary makes it sound like almost *everything* can be edited concurrently. Have they just been really clever about how to separate every tiny little piece of data, so every detail is considered an asset? (And of course, they would need a clever way to store how information is mapped to assets, so the mappings themselves are not the cause of conflicts.)

    Don't enzymes need to be produced by the body? (I.e., they aren't alive and won't replicate just because we're feeding them.)

    On the other hand, maybe the body will start producing enzymes when they're needed, in some cases. Is there a microbiologist/nutritionist in the house?

  9. Re:Implications on Japanese Guts Are Made For Sushi · · Score: 1

    Enzymes aren't the same as gut bacteria--our body actually produces them. I've been told that whether a person produces a given enzyme (like lactase) partly depends on their habits (if they continue drinking milk throughout their lives), but I believe there's also a strong genetic component.

    Do all ads pay per click, nowadays? Because I think I've only clicked one ad in the past year, so I shouldn't feel guilty about bypassing ads.

    On the other hand, if some ads still pay per page-view, then I might want to think about tweaking my ad-blocking so that I don't block ads on a domain until they do something that bothers me (ad with sound, ads that severly slow down a page, inappropriate ad, etc.)

    Why would the word jewry be offensive?

    The word isn't offensive--it would only be offensive if the church was claiming to be Jewish. (I had before never heard "Jewry" used as a location--only things like the "Jewish Quarter".)

    To understand why it's offensive when Christians say they're Jews, imagine you're a Catholic. Some guy (born Catholic) takes your Bible and starts a cult around it, decrying old tenets, adding new and incompatible beliefs, and worshipping another god (alongside your old God). The cult becomes very big, many times more numerous than Catholicism. Then some members of this cult start calling it Catholicism. You might feel like your own culture was a little threatened.

    Yeah, you're right. The article says at one point that "we don't have modern antibiotics, because if we had them here, doctors would use them." I incorrectly interpreted that to mean that they just don't use modern antibiotics, no matter how serious the infection.

  20. Re:What? Of course it does. on How Norway Fought Staph Infections · · Score: 1

    I clarified here But what I meant was that in the great majority of cases, if you get staph in the US, your situation is the same as if you get it in Norway: you will either be given antibiotics that don't work, or you will not be given antibiotics. In either case, your body has to fight off the infection on its own, which takes time, but we don't have a better way. (The caveat is that Norway does use antibiotics if a patient's life is in danger.)

  21. Re:Article is confusing on How Norway Fought Staph Infections · · Score: 1

    Sorry to reply to myself, but I didn't read the whole article before. Apparently they do give out antibiotics in the most extreme cases, and that seems much more reasonable than "we don't have MRSA because we just let our Staph victims die."

  22. Article is confusing on How Norway Fought Staph Infections · · Score: 3, Insightful

    As I understood it, there are 2 separate things Norway is doing to fight MRSA, and they are not related (although the article doesn't point that out):

    1. Norway is tracking the spread of Staph and quarantining victims to limit the spread.

    2. According to the article, Norway isn't prescribing modern antibiotics. This ensures that the Staph that is being passed around Norway probably isn't resistant to antibiotics. This does not make Staph less problematic or control its spread in any way. I'm all for stemming the overuse of antibiotics, but this article smacked of propaganda--or it simply didn't tell the whole story.

    I would add that if your goal is to get a job offer, learning is as important as doing a good job. I interned with a film company, and by all feedback I got, I did great work for them. But by the end of the internship, I hadn't really learned all their products and hadn't gained enough background to be a really attractive hire. They didn't offer me a job--I believe I would have had a better chance if I had asked twice as many questions (about things that weren't related to my current project) and learned a lot more about the domain--for the OP, that may mean learning about how a wireless stack works, even if your job is system administration stuff, for example.
