Cell Phones Responsible For Next Internet Worm?
nitsudima writes "The mobile devices you know and love are great for productivity, but they have completely changed the vulnerability state of our networks. Norm Laudermilch tells you why you should be afraid, very afraid." From the article: "The new and largely unexplored propagation vector for malicious code distribution is mobile devices. With 802.11, Bluetooth, WiFI, WiMAX, MMS, Infrared, and cellular data capabilities on almost all new models, these devices provide a wealth of opportunity for the transmission of data. With no notion of user access levels in the compact mobile operating systems, a lack of effective authentication, and no data encryption, these environments are prime targets for the incubation of malicious code."
No, seriously, what aren't they thinking of using cell phones for these days, except maybe making reliable, clear, and simple phone calls? Seems like the piling on of more non-cell-phone features on cell phones is not very well thought out. Couple the lack of security design in these added networking features with the possibility/probability more mobile phones are moving to embedded Windows (at least that's what I've read), potential for network compromise and disaster increases non-linearly (upward).
What I find annoying and intrusive about this is I'm sitting here in my (our) internet universe working hard to make it reasonably sound, and these entrepreneurs trump that work with their one-off, disposable technology. So, I (we) eventually take the big hit for their irresponsibility. Sheesh, in every major park I've visited there's a requirement for pet owners to clean up after their pets, it'd be nice to see similar structure here.
When they're designing these phones, and these networks, and what and how the phones work, does anyone in the room bring up the notion these phones first and foremost should be phones?
In haste to be the first with the new features it seems the ramifications of what and how they add are considered little, if at all. It's money grabbing, and let the chips fall where they may, as long as the manufacturer is first and fastest with the latest new features. Sick.
I find it ironic, paradoxical(?), one of the features so darling and network centric is text messaging. I've referenced this before the T-Mobile Sidekick got written into an episode of Gilmore Girls where Rory carried on a "conversation" with Daddy about arrangements to attend a function. I'm waiting for the next great headlines where someone discovered the newest and fastest way to communicate with one of these devices -- you can actually dial a number and talk to the other person!!!
As for the "The mobile devices you know and love are great for productivity" statement, give me a break. Firstly I don't "love" them, and if by "great for productivity" you mean: great for interrupting the social flow of interaction; great for rude behavior; great for ignoring real world, then, okay, great! Not.
(And, for those who feel they must beat me with their clue sticks, no thanks on advice about how to get phones that are just phones -- been there, done that... I know how to get around the system, I just don't think I should have to.)
Says somebody who has clearly never programmed a mobile phone.
The vast, vast majority of consumer phones are not the so-called "smartphones" that run traditional operating systems like Symbian or Windows, they run proprietary operating systems that have no publically known names and do not export any APIs, except for J2ME or possibly BREW.
As an aside, J2ME consumer phones are often just as "smart" as larger, more powerful phone/PDA hybrids ... my own does calendaring, web access, has an IMAP client built in, is themable, plays music and videos, and has a 500mb flash storage facility amongst other capabilities. Yet by the standard definition it is not "smart".
Anyway, J2ME has many flaws, but security is not one of them. If somebody finds a programmatic way to compromise a J2ME phone in the next 5 years then I will be very surprised. These things have no concept of processes or users, which is great, because this sort of security confuses the crap out of pretty much anybody who isn't steeped in UNIX security lore. Instead they rely on constructing (with a bit of help) a mathematical proof that the Java programs they're running don't compromise type safety, and then either interpret them or on Jazelle-based phones run them direct on the chip. This is safe and allows for a very flexible and intuitive form of security.
The absolute best you can do on these things is social engineering or exploiting piss-poor UI (which is what Cabir does). To claim you could "infect a cafe full of phones" is ludicrous: most people don't even have Bluetooth switched on as many phones disable it by default.
