Vendors of commonly used software – particularly Microsoft, but also Apple, Adobe and others – battle daily to remove the holes that can be exploited by malware authors.

Nowadays, most of these are really off-the-wall, such as getting a seemingly harmless PDF file to run some of the malicious code on the user's machine.

Even Mac OS X systems have been vulnerable to drive-by downloads.ĭrive-by downloads are almost always done through exploit vectors in commonly installed client software. In this scenario the software is installed automatically without their cooperation. Most malware is installed by a drive-by download.

But this sort of vector, where the user explicitly commands the machine to install the malware, is a tiny minority of all attacks. Sandboxing, and other measures favoured by app store owners, looks to "harden" vectors related to direct installation. You can either cede this control by installing software which has hidden functionality, or you can suffer a "drive-by download" (more in a moment). Thus the ultimate objective of the malware criminal is to find a vector that cedes some or all of the control of your computer to them. enlisting your computer in a botnet that sends spam, or finds victims and defrauds them). a keylogger that steals your online banking password), or to facilitate some other criminal act (e.g. Those purposes are either to directly steal from you (e.g. When we examine malware, either on a personal computer at your mum's house or on a server in a FTSE 100 business, the criminal's overarching intent is to co-opt the machine for his (occasionally her) own purposes. In the vast majority of cases, people who have the skills to write things such as viruses, worms, rootkits, keyloggers, or botnets choose not to because they operate morally within the rules of reasonable society. Malware authors, like all criminals, are in every case looking to exploit a weakness in a system for gain, usually to some innocent party's loss. It's easy to give a type of software a cutesy name, like "malware", but what we're actually talking about here is perpetration of premeditated, criminal acts. It also dramatically stifles the industry's ability to innovate on the platform. Sandboxing and the other measures imposed by the app store owners lulls users into a dangerously false sense of security by implying that apps which run in a sandbox are automatically not malicious - which simply is not true. If you only watch one YouTube video today, watch this one: Here's just one - particularly terrifying - example via Daring Fireball that shows how an app-store-acceptable app can be crafted to download and execute an arbitrary payload that gives total control over the device. As we'll see, the real menace to computing, both mobile and desktop, has been that it's all but impossible for vendors to remove "holes" in system software, or commonly installed apps, that can be exploited. The issue that we developers have is that app store owners can arbitrarily define hoops that we have to jump through in order to get our code up there, but that's not the problem. Apple's move with regards to requiring developers to implement sandboxing with the Mac App Store (MAS) and OS X route implies that its engineers feel it's proven such a good idea on the iPhone and iPad that Mac users might as well "benefit" as well.
In the mobile world we've typically always had sandboxing. A common example is that sandboxed applications typically cannot write to any folder on disk that they fancy. Sandboxing looks to control the rights of installed applications so that they don't automatically have carte blanche over the whole machine. Normal software applications, once installed, usually have free rein over the entire computer and its peripherals.
