The Desktop Security Battle May Be Lost 389

Trailrunner7 writes in with a Threatpost.com article that begins: "For years, security experts, analysts and even users have been lamenting the state of desktop security. Viruses, spam, Trojans and rootkits have added up to create an ugly picture. But, the good news is that the desktop security battle may be over. The less-than-good news, however, is that we may have lost it. Jeremiah Grossman, CTO of WhiteHat Security, said Thursday that many organizations, particularly in the financial services industry, have gotten to the point of assuming that their customers' desktops are compromised. And moving forward from that assumption, things don't get much prettier." It goes on to speculate about home routers being targeted and infected.

      The major problem we actually are suffering from is that the world depends way too much on a single environment. And that environment is a kludge.

      I'm not saying that Linux is much better - just somewhat better since it isn't as integrated as Windows.

      As for losing the battle - this is a battle you only lose when you give up. As long as you persist you won't lose. You may get some beating now and then, but that's not a big issue since you can come back.

        If you'd have read the article, you'd know that home networks are the new frontier for hackers and a big reason why security experts are giving up the desktop fight to focus on the network instead. From the article: "... it won’t matter if PCs are disinfected, swapped out, or replaced with iPads, the bad guys are still control because they own the network below." So the old Blame Windows standard won't work in this case.

Yes, Linux is being attacked (successfully), as is Mac OSX. The attacks on home routers are particularly heinous as most people do not update/upgrade the firmware ever, and more of it is based on common Linux underpinnings.

        It's true. And I've actuall recieved one of these attacks on Routers before, and it ain't pretty.

        So I live with 2 room mates. One of them (we'll call him A) doesn't know a lot about computers besides they play awesome video games. The other (We'll call him B) one loves computers and how he can Torrent "1080p" movies before the blu ray even comes out. He knows enough about computers to set the basic stuff up himself, and I'm sure the average user would call him good with computers, but you or I would be able to tell right away that he's just above average.

        So B downloads a movie. I believe it was Sherlock Holmes. Anyways, he moves it to this external Hard Drive we have laying around, then tries it on his desktop in the living room to see if it works. Video plays, but then he starts getting pop ups. "Dang" he tells himself, tries using the BitDefender online scanner as he leaves for work. A comes home from work a couple hours later, moves the External Hard Drive to the Xbox360, notices Holmes is on there, and tries playing it. It doesn't work. So he moves it over to his desktop in his room, tries it, Hey it plays! But now he's got pop ups as well.

        So I come home, and I decide I want to put on a movie. I move the external hard drive back to the 360 because its got Office Space on it, and watching that movie after a hard days work makes me feel better about not stealing from my company. Anyways, I notice Sherlock Holmes is on it, but I mean we saw it in theatres like a couple months ago so no reason to watch it again just yet. I open up B's desktop to surf the net while watching the movie. Pop ups. Well we'll clean that later. Dealt with enough stuff at work, not in the mood. So I bring out my laptop. That's odd, somethings hijacking my browser. So I boot into safe mode and run a scan on it. Nothing. That annoys the hell out of me. So grab the screw driver, rip out the hard drive, slave it, scan it from my desk top, still nothing. Well what the frack? I put everything back to normal, boot it up, look at the settings. That doesn't look like the regular DNS... though its hard to tell. Same DNS on the desktop. Try browsing the desktop, also getting highjacked.

        Okay, so I log into the gateway. Telus gave us this really crappy DSL/Wireless router. I never changed the admin password (admin/telus) on it, but I put a wireless password on it, my initial premise being that should Telus need to remote in for any other issue there wouldn't be an issue, and the only way someone would get into our network was either breaking PSA2/AES or by plugging in locally. In hindsight that was a bit of a mistake. Anyways, so I look at the router and it's DNS was changed from automatically retrieve to the bad DNS.

        Alright. So I change the admin password and change the DNS back, and unplug everyone but me from the router. Don't want the infected machines pushing out the DNS again. I spend the rest of the evening slaving the 2 infected Desktops and cleaning them off, and even checking the 360 hard drive (cause you never know if they've somehow managed to write a virus for that, but luckily it didn't get infected). Then putting everything back to normal. A and B were a little pissed because they were without internet, and without their computers for a little while (which just made me upset because I didn't start the problem, but I had to fix it).

        After everything was working and we were done yelling at each other, we all played a game Age of Empires 2, co-operatively against computers. It's like Make up sex for nerds. But to be honest, I still get a little tired of having to deal with that kind of stuff. We're all moving out in July.

      Actually, it seems like a reasonable assumption to me. Always code or design assuming the worst. Before you decide what hoops you make the user jump through to get his money online, assume that he's pwned in every imaginable way, that his firewall is mis-configured to be a digital goatse ;) and probably he's not even who he says he is. And he's probably trying to break your system too. Because sooner or later you'll have to deal with just that. Now what can you do to mitigate such a situation?

      Basically you can divide people and design philosophies into a spectrum between:

      - optimistic: they expect the best possible outcome. They just know it'll be all right. The world is nice, the users do exactly the click sequence they've been told to, and his functions only receive exactly the right input.

      - pessimistic: they expect that Murphy's Law is actually a law of the universe, and if something could possibly go wrong without violating the laws of physics, it will. Actually the real serious pessimists don't even exclude the laws of physics going wrong. They tend to have the speed of light as a variable ;) They also tend to bring a sweater or two along when going to the beach in Florida in August. And they just know that some bastard out there will feed their program the wrong input, or will have his password stolen by a keylogger and then sue when he finds his account empty. They tend to rarely be disappointed in those expectations, actually.

      Personally I like my programs and processes designed by the latter. And it seems to me like this is what those banks are doing. They're for a change starting from the worst possible scenario as an assumption. Nothing wrong with that.

    We need to assign responsibility to those who can do something about it.

    Every day, my firewall emails me a list of port scans against it, sorted by IP address. Most days that list is just under 100 different IP addresses scanning me, some days it is in the thousands of IP addresses - from all over the Internet (i.e. not just local addresses). This is on a residential DSL connection that offers no services to the world, isn't linked to by any web sites, and does not respond to any unsolicited traffic.

    It seems reasonable to assume that most if not all of those IP addresses represent infected machines. Were there some way to get them shut down, imagine how much cleaner the Internet would be. However, there IS no way to do so: the ISPs hosting those machines don't provide any meaningful or automated way to report them, there is no way to contact the owner of those machines, so they just keep on spewing and infecting the rest of the system.

    Nor will ISPs ever provide an automated way of reporting such machines as things stand now: a reporting mechanism is an internalized cost, and there is no reason for an ISP to internalize that cost when they can externalize it to the rest of the Internet.

    This is one of those rare cases where "there ought to be a law" is a reasonable response: were ISPs required by law to investigate abuse reports and disconnect infected clients until those clients are cleaned up, the number of infected machines on the Internet would be reduced, the profit margins of the bot-herders and spammers wiped out, and the system would clean itself up. However, such a law would be fought most vigorously by all ISPs precisely because it would be internalizing a currently externalized cost, and it would be worth vastly more to ISPs to prevent such a law than the cost of lobbying against it.

    (NB: "repeatedly submitting false abuse reports" is itself abuse, and should also result in the source of the false reports being shut down).

The department I'm part of has a border firewall, client firewalls, no one runs as administrator, antivirus, spyware, malware checkers are run on a regular basis. More important than any of those: we spend time to educate our users on security. They know what to avoid in terms of phishing scams, never to give out passwords to anyone, what to look for before you click on a link in an email (or even a website), etc.

    One thing I loved about the ThinkNIC I set up for my mom so many years ago was that it was impossible to break. It booted from read-only media (a CD) so I knew that mom could never screw up anything in her computer permanently. The worst possible crash could be fixed by just turning it off and back on.

    With so many folks pushing "cloud-based" solutions for, well, everything - Why hasn't something like the ThinkNIC come back?

    A little box with any sort of read-only memory could hold all the programs most users will ever want. Make that memory in the form of some sort of plug-in card, and the entire machine would be easy to upgrade. (ThinkNIC used to send out new CDs with the latest versions of their setup.) It would also be easy to fix if a security problem were found; just mail out a new SD card or whatever.

    Banks could advertise "Real Security. Because we care." They could give away a small computer to customers with the promise that said little box would enable streamlined access to their accounts, all while doing nearly everything an adult could need from a computer.
