A gaping hole in the iPhone 3G S's beefed up security, allows a packet of code to be fired into it via SMS and compromise the entire system. Apple says that it will fix the major flaw by the end of July.  (Source: AppleIPhoneReview)
IPhone SMS vulnerability could allow malicious users to install and execute malware

Recently, Apple has struggled with the security ramifications of a higher commercial profile, and seeing an increasing number of OS X malware.  Now another security flaw has been found, this time in the iPhone OS.  The flaw allows attackers to gain root access to the iPhone's underlying OS, allowing them to install and execute malicious programs at will.

The iPhone apparently automatically executes binary code sent in SMS messages.  Messages are limited to 140 bytes, but this is little deterrence as longer programs can be broken up into several messages, which the phone automatically reassembles.  While other applications such as the Safari browser on the phone only enjoy access to their sandbox, the SMS system is automatically granted root access, and SMS commands execute as root.

Charlie Miller, during a presentation at the SyScan conference in Singapore on Thursday introduced the vulnerability to the public.  He declined to go into specific details or offer his proof-of-concept code to the public, as he has entered under an agreement with Apple.  Mr. Miller did state, "SMS is a great vector to attack the iPhone."

He went on to describe several examples of how such an attack could prove beneficial to malicious parties.  Among his ideas were to use the phone's GPS technology to track people, to turn on the phone's microphone to snoop on meetings or conversations, and to use groups of the infected phones to form a botnet and launch distributed denial-of-service attacks.

Apple will have a fix ready by the end July, it says.  Mr. Miller says he will hold off on releasing details of his attack until then.  He will present the attack in its full glory at the Black Hat USA 2009 conference in Las Vegas.  Mr. Miller is the author of The Mac Hacker's Handbook, one of the leading resources for prospective Apple hackers.

He praises Apple's efforts with the iPhone saying that the stripped down version of OS X provides less attack opportunities.  He says that lack of support for Adobe Flash and Java while an annoyance to users actually aid security, as these are traditional attack vectors.  He also notes the phone's provisions to only run Apple-signed code and to provide hardware encryption as other promising features.  

Many of these features were added in the new iPhone 3G S, but were not present in the iPhone 3G leading the iPhone 3G to receive failing marks in a recent security study.  Mr. Miller concludes, "The iPhone is more secure than OS X, but SMS could be a critical vulnerability."

no, i replied to it and you are still an idiot who does not understand what a native up is and what a non-native app is. post whatever links you like, you just make us laugh more.

go back to your screw driver. go replace some dead sound card or something, you are out of your league here.

sorry for the "up" typo. been going for a day without sleep here.

by the way, my understanding of your first post is that you endorse cutting off java and flash in the name of security. am i correct? please say yes so we can get some laughs.

I wonder where did you get that "native Mac apps require sucking iDick before publishing" lunacy? Can I read your source? I know it exists solely in your imagination, but it may got started after reading a post of similarly ill person ot something? So, will you provide a link or any other kind of proof? Anything?

learn about native apps and then argue. native apps on osx go through the same process that iphone apps go through. this does not prevent malware in any way and it just gives monopolistic control on the platform.

so for instance, open office runs on the mac just fine and it does not require approval because it is java based and it is not a native app. similarly anyone who can write malware takes a similar route, whether that be scripts or trojan apps or anything else.

sorry i cannot come up with a car analogy for you.

So if I make you a native Mac app in XCode that displays window with a sign saying "Jobs sucks my balls and fsardis too" - will you shut up then? ;-) You do know that Apple would never approve such an app, so there must be a contradiction, right?

so then, can you explain to me how the content restrictions aid in malware prevention?
this is what you claimed before and now you are claiming something else.
if you can indeed do such an app, you have proven that you are wrong and content restrictions do not prevent malware. you will also prove that i am wrong about the authorisation. knock your self out champ.

There are no content restrictions for a Mac, stop smoking crack :)
