Adrian Ludwig speaking at Black Hat USA 2015
Well yes, they absolutely are.
Google is basing its claims on wildly incomplete dataBut let’s start with the facts: as Ludwig claims, Stagefright has resulted in zero confirmed infections in the wild – data based on Google Play Services’ built-in malware detection. All that is good and well, except he conveniently forgets to mention the fact that Google Play is unavailable in a number of countries, most notably China, which also happens to be one of the biggest smartphone markets in the world.
So his claim that no Stagefright exploits exist is based on wildly incomplete data, which also just so happens to fit a “pattern” he noticed – this is military-grade disinformation at its best, and it coming from the head of security for the most widely used mobile OS in the world is downright scary.
But never mind the Chinese – what’s important is no Americans were infected, right? Except that’s not concrete information, either: Ludwig claims no confirmed cases exist, raising the possibility that there were, or maybe even still are, probable candidates. And let’s not even begin discussing the fallibility of Google’s malware detection, which has failed a number of times in the past.
Ludwig may be technically correct, but he's still missing the pointLudwig did have a point, however: regular users needn’t worry about being hacked by elaborate means such as exploiting Stagefright or its brethren – phishing and adware are a much more common occurence, especially in the mobile world. So the everyday consumer is much more likely to infect themselves, due to their own stupidity and/or ignorance, rather than become an unwitting target of malware.
But this line of thinking is just simple misdirection: while users don’t have to worry about being hacked, the threat of hacking itself is still of great importance, and on a much larger scale to boot. As of a few years back, government officials in the United States are approved to use smartphones when handling classified data. To meet the required security standards, Android devices run specialized forks of the OS with a number of cut features, which presumably include Google Play Services. Or in other words: Google doesn’t have data on one of the biggest markets in the world and one of the most prolific targets of elaborate hacks.
The Qatari government's phishing tactics involved creating fake social media profiles
As for the obvious question this poses: “Why should I care about Qatar?”, consider this: as of March 2015, it's officially the richest country in the whole world, and is also one of the biggest players in the oil industry. It’s also run by a laughably corrupt government with no regard for human rights, a trend which seems to be getting ever so popular these days. Autocracies like these have both the desire and the resources to exploit vulnerabilities like Stagefright, and use them against their opposition. And who’s to say there isn’t a treasure trove of undiscovered bugs stashed somewhere right now, waiting to get abused?
Yet despite all that, the big G has the audacity to claim worrying about security is meaningless. Well guess what, Google, it isn’t – even just a single successful exploit at the right place and time could be disastrous to millions of people, and it’s your job to protect everyone from it. So how about instead of conducting smear campaigns against security researchers, you try not leaving gaping holes in your code instead, okay?
