Google Finally Uses Remote Kill Switch On Malware

Hugh Pickens writes writes "The Google Mobile Team has announced that in addition to removing the 21 malicious applications from Android Market that were downloaded 50,000 times, suspending the associated developer accounts, and contacting law enforcement about the attacks, they are remotely removing the malicious applications from affected devices. 'We are pushing an Android Market security update to all affected devices that undoes the exploits to prevent the attacker(s) from accessing any more information from affected devices,' wrote the team on their blog. 'For affected devices, we believe that the only information the attacker(s) were able to gather was device-specific (IMEI/IMSI, unique codes which are used to identify mobile devices, and the version of Android running on your device).' Google's actions come after numerous complaints in tech publications. "Does Google really want its Android Market to gain the reputation of being a cesspool of malware? 'Certainly not,' wrote Nicholas Deleon in TechCrunch. 'But then part of the allure of the Android Market is that it's open; you don't have to play by Google's rules, per se, to get on there like you do with Apple's App Store.'"

      As for the removal tool Google is planning to send. If the virus programmers have any sort of brain the first thing they're going to do is block the removal tool from removing the rootkit by sending a patch to the rootkit. It wouldn't surprise me if the rootkit doesn't phone home soon and download something to either spoof that the rootkit was removed or block the rootkit remover altogether and disable apps (either from Google or a third party) designed to remove the exploit. Google giving them a heads up through the blog post that they got 72 hours to code such a patch just made the virus writers job even easier.

      Now I'm not saying that Google is handling this totally incorrectly. If I was Google, I would have taken many of the steps that they are currently doing, except I would not publicly lay out the plan until after it was executed. I know it would give Google Bad PR by sending apps without user knowledge, but it would have minimized a counterattack time frame from the virus writers and would have been the safer option overall.

"If it's serious enough to use a kill switch, it's serious enough that someone will be filing a lawsuit, and we're sure enough of it that we're reporting it to police (under threat of perjury)."

    This is probably the best compromise. Obviously, some people would prefer no kill switch at all, while others would like the kill switch to be used on practically anything they don't like. If "serious enough and sure enough to sue" is the standard being used, it won't affect free speech (since, if you would be sued over it already, we've already lost that battle), and it makes accidents much less likely. Now, requiring that lawsuit to be won would make it even safer, but you run into the problem of it continuing to do damage for the years it takes to finally settle the suit.

MOST users are not tech savvy, and therefore MOST users aren't even going to know what to look for to try and avoid malware like this. Whats worse is that MOST users think Google is a trustworthy company so they will assume that the official Android Marketplace that ships on their phones and is provided by Google is a safe place to obtain apps. As we have found out recently, that is far from the truth. Google's free-for-all marketplace approach is harmful to average users. I'm not saying that the answer is to lock down Android to he same extent that Apple and Microsoft have done, but the totally open Android Marketplace should be an alternative, not the primary source. As the provider of the experience Google needs to set up a trusted marketplace where they put more scrutiny and oversight into apps and make THAT the default experience for the user.
