Google Chromebook - a new class of security risks

By | May 12, 2011, 8:06am PDT

Summary: Costin Raiu argues that Google’s coming Chromebook computer concept presents an interesting new set of security problems, especially as it relates to cloud computing.

Guest editorial by Costin Raiu

We are certainly living in interesting times. It was less than a week ago that a rumor appeared that Apple is going to switch to ARM processors for its next generation of laptops.

Obviously, this has very interesting implications for the future of computing and seems to indicate the increasing need for a computing platform that uses less power and that can be used for a day without the need for charging.

Earlier today, Google followed up by announcing the Google Chromebook – a netbook (huh, aren’t netbooks dead?) computer concept, built for now by Samsung and Acer around the Atom N750 CPUs. With 2GB of RAM and 16GB of SSD storage, the specifications are somehow low-end, however, this might not be a problem because as Google says in their promo, the web has more storage space than any computer. The price, when these will be available, is believed to be in the range of $400-$500.

When I saw the announcement, I thought to myself – why would anybody ever buy something like this?

Low end hardware, more expensive than other netbooks and definitively not as attractive as an iPad?

Obviously, the answer here is in the “cloud.” Google Chrome OS is the first commercially available consumer cloud-centric OS. It is designed around the concept of “expendable” terminals that you can lose, drop or simply throw away without fear of losing your data, which is safely stored into the cloud. From this point of view, the operating system could get damaged or even infected with malware and all you have to do is to reinstall it and re-authenticate with the cloud storage to get exactly the same computing experience as before the crash. Here, I would like to make a mention about the “infected with malware” part. Interesting, Google’s promo claims “it doesn’t need virus protection”.

Sadly, this claim comes at a pretty bad time, since the French company VUPEN Security announced only a few days ago that they’ve cracked the security protections build by Google into Chrome and are now able to infect a computer through a malicious page when it’s browsed.

Google Chrome hacked with sophisticated exploit ]

Of course, some might say, “even if I get infected, I’ll just reinstall, put back my credentials and bye bye virus!”. I agree that is absolutely true – Chrome OS has been designed in such a way that it’s extremely resilient to modifications and has a good self healing capability.

Several years ago, I wrote an article saying that malware evolves based on three conditions:

  • When hardware and operating system evolve (eg. Windows 95 killed boot viruses)
  • When security defenses change (eg. firewalls killed network worms)
  • When people start using computers in a different way (eg. Social networks)

With the Chromebook, we have an interesting case, when all these three conditions are met. It’s a (somehow-)new operating system, it has new security defenses into place (self healing, updates) and it’s used in a different way – the data is not on the computer but in the cloud.

So, what can we expect from a security point of view? Obviously, with all your data being available into the cloud, in one place, available 24/7 through a fast internet link, this will be a goldmine for cybercriminals. All that is necessary here is to get hold of the authentication tokens required to access the cloud account; this is already happening with malware that has become “steal everything” in the past few years. Although the endpoint is now more secure, the situation is that the data is in a more risky place and it will be much easier to silently steal it.

Most of the attacks nowadays focus on infecting the machine and then hiding the presence of the malware for as much time as possible to intercept banking transactions or credit card numbers.

With Cloud centric OS’es, the race will be towards stealing access credentials, after which, it’s game over. Who needs to steal banking accounts, when you have Google Checkout? Or, who needs to monitor passwords, when they’re all nicely stored into the Google Dashboard?

Of course, this could seem a bit gloomy, but these problems are inherent to any Cloud-centric OS. Earlier today, I got asked by a friend– “How is Chrome OS from a security point of view, better or worse?”

I answered, “It’s better, but much worse.”

A malicious extension or other addon can certain get into the browser through a security flaw in Java, Flash, or some native hole, and just steal a bunch of passwords in realtime with a keylogger. Since Google tracks everything in the address bar, it wouldn't take much to steal that info either - just redirect the address bar keystrokes to another site and you can instantly track any user, keystroke by keystroke.

It is much better to access cloud applications from a secure computer rather than an insecure computer. The security problems related to the cloud are all centered around Accessing cloud applications from Windows. The number of attack vectors for Windows computers is an order of magnitude greater than just about anything else.

@DonnieBoy

Chrome OS is still that: an OS, running locally on the hardware. It still has a Linux kernel, which is not immune to attacks, nor is the browser. And you have a user in front of the screen, which is 100% of the reason why social engineering attacks work. You same people that say that Chrome OS is totally safe were the same ones that said that Linux is immune to malware. Parrot it all you want. We know how well that worked for Android....
OS. ChromeOS is not just another Linux kernel either, there are a number of important changes to make it more secure and sanbox everything possible. It is ridiculous to say that because there are other security problems, the security of the OS does not matter.

Google said the same thing about Android.

Speaking about Linux, where is the source code documenting all of these changes? Oh, that's right! Google doesn't want to play fair in the FLOSS arena.

Also, this statement makes absolutely no sense: "It is ridiculous to say that because there are other security problems, the security of the OS does not matter". With that single statement you not only contradict yourself, but you also prove my point for me.

Yet Google fanboys are all over this, condemning anyone who isn't ready to throw all our dataz at Google with open arms.

This is exactly why ChromeOS won't take off. I for one would NOT trust my data at all to someone who has be hacked before in a high profile case.

Should they be hacked again, and with people's data stored on their servers, which menas people will try, it's game over. You loose everything.

@DonnieBoy Okay let's just agree with you for a second... the cloud is the future. What compelling things does Google bring to the table? Security? No - that's already been proven to be false just in this blog article. What "killer" application.... or rather... what "value" do we get? Also, who in their right mind is going to cut off their nose despite their face? This is a play toy concept with hopes of grandeur... let's be honest here.

Google figures it's going to invest its way into the PC space and carve out a niche. With their ability to retain customers, their roadmap of product failures, and their inability to retain search marketshare Larry and Co are in for some interesting times.... I don't think they have a chance in hell.

"People are switching to the could WITH OR WITHOUT ChromeOS." and rebuttal...
People are not switching to the cloud WITH OR WITHOUT ChromeOS.

I for one will not use Google for anything as I don't believe in their business practices on collecting data and cramming adverts in your face every chance they get. Never been a fan of commercials nor stupid ads on the net. Another thing in their privacy statement sums up that say for instance you had an idea or an invention... If you email it out over Google they have the right to your idea as theirs and can patent it and leave you out of it 100%... Sound fair? I think not. Also the need for a network connection? Nah... I like to do things at my convenience. Put all my eggs in one basket and leave it out in traffic hoping it never gets run over? Again I think not. Using half assed web apps dumbed down with limited capabilities and requirement to be online at all times being tracked on all levels? Nope again I think not. If anything cloud brings compatibility to the web but giving up all your data and rights is out of the question for most. I will be laughing when the next solar flare hits and knocks out cell towers radio signals and every fool gets to sit there and enjoy nothing as the could has thus evaporated. At least with a real computer I can still do everything offline wink

Also... "Google is NOT the cloud, just one provider. You can use ChromeOS without using Google services."

How so? ChromeOS is web dependent, What is the point of buying a 400-500 dollar netbook with a crap OS that depends on the internet when you can get a netbook at 400-500 dollars that is not web dependent and does cloud and can play games like SC2 if you wanted and runs Windows? Sounds like there is really no savings from Google's offerings.

@John Forbes

I would have to say it is. For instance look up the Asus 1215N... 12.1 inch screen full keyboard and so on and it is a netbook. I was one of the first 5 in the USA to have a netbook with the EEE PC 4G which was a 7"... Over time they became larger and the main underlying factor to consider it a netbook was the fact there is no optical drive. I would feel the best descrption is a Laptop smaller than 13 inches with an atom processor and no optical drive.

On the other hand Google's I wouldn't know what to call it aside of maybe a door stop or something of that nature. Paper weight?

My door stop and paperweight took offense to your last remark. They demand an apology.
@John Forbes

"Thin clients for the web." I kinda thought that was what the 'net' in netbook meant.
There are so many fewer attack vectors for ChromeOS that there is just no comparison. People will be losing credentials NOT from using a ChromeOS computer, but, from accessing accounts from Windows computers. The switch to the cloud is for ALL computers, not just ChromeOS. If people only accessed their applications from ChromeOS, they would be much, much safer. To somehow put the burden of all of the security issues of the cloud on ChromeOS is pretty ridiculous. In any case, the security issues of the cloud are nothing compared to all of the problems with Windows. Almost all of the issues of cloud security are centered around people accessing the cloud from a Windows computer.

Well said! Thanks for pointing out what's obvious to nearly everyone (except ms-hating DonnieBoy and perhaps a few other misinformed users). Despite DonnieBoy's claims that he repeats, and repeats, and repeats... ad infinitum, Windows OS has been shown in test after test to be the MOST secure OS available. It's attacked so often for the QUITE SIMPLE reason that approximately 93%+ of computers worldwide run some version of Windows. Why would a hacker spend time finding exploits for operating systems that comprise less than 7% of the machines worldwide? He (or she) would have to be an idiot to do that when there's almost nothing to be gained and I doubt many hackers are idiots...

Using Google is like opening up your life, bank records, finances, and other tid bits about you and your life to the Chinese government.

Tell me Donnie, you seem to be in Google's pants. What exactly is Google going to do with our data? What kind of third parties are they going to open it to? What Governments are they going to open it to? How exactly are they going to secure their datacenters? How do they plan from being the next SONY? Are they going to stab users in the back again with another Buzz? Why should users hand ouver thier hard drives to Google when more and more are becoming more adept at handling it themselves? And why should I pay thousands of dollars over three years for a glorified paperweight?

First of all you in English grammar you do not want to put two opposite words together, (e.g. "many fewer")

"Almost all of the issues of cloud security are centered around people accessing the cloud from a Windows computer."

This is because of market share. If Scroogle had 90+% market share they would be culprit of the same issues, hence why they are eying Google's search results to malware attacks and not so much other search engines. At least Bing monitors theirs and blocks and or warns for potentially dangerous sites. Windows is secure and will continue to be secure or at least in the instance they fix their vulnerabilities and security suites exist unlike most other platforms that are not ready for threats. Google is spyware doing the same things that even Real Player was doing back in the day and got sued for but somehow it's okay for Google to do it? PASS... I'll stick with Windows and Linux that hasn't been ruined by Scroogle.

Just so you know, Ryan, the malware infecting Chrome is Windows only malware (Chrome OS is Linux-based) and a virus cannot even write itself to Chrome OS without attempting to write to a read-only root file system. Fools and blind! Don't you see that if a file system is read-only it CANNOT be written to by a virus?

Have you thought about social engineering? You know, that attack vector that plays on user's lack of education about malware? All cybercriminals would have to do is create a scheme to trick users into giving up their credentials, and boom, Fort Knox has just been compromised.

THe user is the biggest risk to any operating system/network infrastructure, not the OS.

I think that's what they are all missing
LiquidLearner 12th May 2011
@Cylon Centurion 0005

If a user gets tricked into going to a fake Blizzard site on the web, they may give up their credentials to their Battle.net account. Their other online accounts would be safe. With ChromeOS they simply need to trick the user into giving up their Google account info and you're screwed. They have all of your data, immediately, and you might not even know it. Great, your computer didn't get infected. But they still got the keys to the kingdom.

With Google's system, and many cloud services like this (I fear with Win 8 profile sync), is that without even being infected you could give up access to EVERYTHING. And be none the wiser until you go to get gas and your card is declined.

I don't hate Google and I don't think they're some evil corporation. I just think they want to make money like every other company on the planet. Simple enough. The ChromeOS locks you into a Google system that is potentially more secure. But if the user makes a mistake it's drastically worse.

Also be aware that they are developing malware kits for other OS's as well. They just released one for Apple OS and there are more coming for iPad, iPod, iPhone and Linux Distros. Since people love to tinker and take some hardware that is only meant for one thing and force it to run another that is "LOCKED ON" the machine and is "read-only" then how did they get CrapOS off and put Windows on? Hmm seems like they were able to work around that "read-only" part and turned it to "read/write". As much as the Linux crowd doesn't want to acknowledge it there are vulnerabilities in Linux kernel and it does get patched. They had one that existed then fixed and some how undid the fix and left it unpatched for almost a year before noticing that it became unpatched... Sound secure? Didn't think so. Or the virus that was in their synaptic package manager for over a year before being discovered? Yeah bout that... Everything has its flaws, nothing is perfect. It is just choice in whether you want a stripped down hooptie that is network dependent or if you want something that is useful online or offline.

Its not about being a Google Fanboy .Its about seeing through everything to find what actually is true. In the end the only condition one can be secure is isolation which is never going to be an option . So no matter how much you harden the system there will always be someone working to find the other way round. All-your-data-in-the-cloud is still and idea most individuals would not approve. ChromeOS claiming that it doesnt need antivirus is a very tall claim. But yes the fact is just writing something off at this stage is also like jumping to conclusions too soon.
will access on premises. ChromeOS does not imply that you have keep you data off-premises.

Where does security begin and end?
Dietrich T. Schmitz, ~-~ Your Linux Advocate 12th May 2011
It is amusing at best that articles like this surface.
As far as I can recall, Google are the only software vendor that has *attempted* to add security sandbox capability to their browser.

Now, I can send you to some 'caveats' that have been kicking around in the Google Code Chromium developer documentation which clearly state that Engineers cannot guarantee the safety of the Windows-based sandbox.

What has been side-stepped by the shock-jock bloggers (Adrian KH) and this author is that Windows 7 64-bit with all its purported security enhancements failed to stop the Vupen exploit.

Where does security end for you? At the App?

For me, I fully expect that security ends with the Operating System.

Now, all the fuss about Windows sandboxing of Chrome was hacked turned into a story of Chrome was not the vector, but rather Adobe Flash.

Ok, fine. You can expect a patch from Adobe just like all the other patches that follow a published Zero-Day.

Same situation different day.

Is it the same? Well, no. ZDnet seems preoccupied now with targeting Google as though the issue of security lay entirely at their feet.

Let's not forget that Windows 7 64-bit has a part in security and should have stopped the exploit.

This scenario would not have happened with Ubuntu Linux equipped with LSM profiled Firefox.

Ubuntu Linux: The safest operating system on the planet.

I stake my reputation on it.
