. Posted by: on 3 June, 2012 11:08 AM. tab name=’News’ Here is something that I’m sure some of you have been waiting for, courtesy of iFixit. As per usual they have managed to get their hands on Samsung’s latest flagship smartphone and take it apart piece by piece.

The specific model number of this is the GT-i9300, which happens to be the international version and not the variant that will be heading to North America, confirmed by the Exynos 4412 quad-core CPU on-board. The CPU is actually manufactured in the same way as Apple’s A5 rev 2 processor, which also happens to be manufactured by Samsung too.

Other components such as the various memory modules are also produced by Samsung. Moving on to connectivity, the SIII features the same Intel Wireless PMB98111X Gold Baseband chipset used on the Galaxy SII. Wi-Fi is dealt with using Broadcom’s BMC 4330 chip, while GPS is also powered by Broadcom’s BCM47511 Monolithic GNSS receiver, finally NFC is provided via the NXP PN544 chip. The process of identifying the components used was fairly easy, as Samsung labelled some parts to reveal their role in operating the phone. Such components included the Melfas 8PL533 Touch Screen Controller, the Wolfson WM1811AE Audio Codec and Maxim Max77686 Power Management IC. There is obviously an abundance of other chipsets included within the Galaxy SIII, although we wanted to point out one you may think is most interesting. That is, that the features exactly the same Sony 8MP back-illuminated used on the iPhone 4S.

So, for all the Apple fans bragging about how good their camera is on their 4S, be prepared to have an influx of owners uploading all their creative shots to Flickr as well, along with equal bragging rights. Let us know your thoughts on our comments below or via our Twitter page.

A Broadcom chip flaw found and demoed by Exodus Intelligence's Nitay Artenstein exposed a potential critical threat to 1 billion Android and iOS smartphones. This exploit was possible due to a specific Broadcom Wi-Fi chip bug that let the hacker gain remote execution access on smartphones. Fortunately, before this could happen, and both have fixed the bug. The Wi-Fi chip is vulnerable to a self-replicating attack, which could spread infect and spread without any user interaction. Ars Technica that this vulnerability was found in the BCM43xx family of Wi-Fi chips manufactured by Broadcom. Artenstein demoed a proof-of-concept attack code that took advantage of the vulnerability at the Black Hat security conference in Las Vegas recently.

This code reportedly fills airwaves with connection requests to nearby devices, and when the request reaches the specified Wi-Fi chipsets' devices particularly; it rewrites the firmware controlling the chip. Then, the compromised chip sends malicious packets to other exploitable devices, creating a domino effect of sorts. Artenstein has dubbed this bug as 'Broadpwn', and this vulnerable chip resides in almost 1 billion smartphones in the market, as mentioned before.

The report states that Artenstein got in touch with Google and Apple both to make them aware about this bug, and Google released a patch early in July to prevent any sort of ripple effect to start. Apple also as well, preventing a potential self-replicating attack to spread to a large number of devices. 'This research is an attempt to demonstrate what such an attack, and such a bug, will look like.

Broadpwn is a fully remote attack against Broadcom's BCM43xx family of Wi-Fi chipsets, which allows for code execution on the main application processor in both Android and iOS. It is based on an unusually powerful 0-day that allowed us to leverage it into a reliable, fully remote exploit,' Artenstein wrote in a. In his post, Anrtenstein explains that in order for the attack to begin, targets don't even have to connect to the malicious network, and simply having Wi-Fi turned on was enough. His attack worked on a number of smartphones, including all iPhone models since the, and Samsung Galaxy flagship devices from Galaxy S3 to the Galaxy S8 launched this year.

The researcher also said that this attack was more vulnerable on smartphones than laptops and computers as they provide limited access to Wi-Fi chipsets, not enabling remote execution at least. For the latest and, follow Gadgets 360 on, and subscribe to our.
