While the iPhone SMS security vulnerability has been hogging the headlines this week, it also emerged from the same conference that Mac OS X is at risk too.Speaking at the Black Hat security event, Mac expert Dino Dai Zovi exposed an OS X coding loophole by installing a rootkit that could give hackers complete control of a Mac, allowing them to take even encrypted data from the other side of the world.
Bank accounts exposed
The 'Machiavelli' technique relies on using the Safari browser to get hold of encrypted data such as bank accounts and other personal information.
Dai Zovi explained his motivation in helping Apple work on better securing its machines, warning that hackers need only target OS X computers for general the Mac security complacency to dissolve into a serious problem.
Fairy dust
"There is no magic fairy dust protecting Macs," he pointed out, while another security expert added, "When the malware authors put out something that's really sophisticated we are going to have a whole population that is really vulnerable."
The flaw allows the hacker to gain access to nearly all access of the phone, meaning the camera, browser and phone functions can be remotely used.
Charlie Miller, the security researcher who uncovered the flaw (along with fellow researcher Collin Mulliner) says he has notified Apple to the problem, and the company hasn't (yet) responded with a patch.
The hack works by sending 512 text messages to a phone (although only one is visible) and then using an exploit in software to let the code from the text overrun into other parts of the phone.
Unknown attacker
The symbol on the one message could actually be changed to anything, so the person wouldn't know they've been the victim of an attack.
The hack will then use the phone to send texts to other users, meaning if left unchecked it could easily spread around the world.
The duo both say they've given Apple more time than ever to respond to the attack, yet it hasn't released a patch, so will be going ahead and revealing the exploit.
They've also found a similar problem with Windows Mobile, but admit they only found that last week and haven't notified Microsoft as yet.
Attendees at the Fortune Brainstorm: TECH conference heard Stone reveal that he has concrete plans to monetise Twitter and that he won't be selling out to Google.
"The key takeaway there is that we're thinking big and we're in it for the long haul," he said.
After the education phase, he plans to move on to add new services to Twitter, including account authentication to avoid identity theft and a possible use for data mined from the user records.
"We started out by creating this very simple status updating system. And that's not what Twitter is. It evolved into something else," he said.
On The Windows Blog communications manager Brandon LeBlanc (funky name) has detailed when the partners and OEMs (and by virtue of bittorent, everyone else) will be able to get it.
"ISV (Independent software vendor) and IHV (Independent hardware vendor) Partners will be able to download Windows 7 RTM from Microsoft Connect or MSDN on August 6th," said Blanc. "Microsoft Partner Program Gold/Certified Members will be able to download Windows 7 RTM in English through the Microsoft Partner Network (MPN) Portal on August 16th. By October 1st, the remaining languages will become available to download. Microsoft Action Pack Subscribers will be about to download Windows 7 RTM in English starting August 23rd. By October 1st, the remaining languages will become available to download."
Blanc goes into even more detail about OEMS ("two days after we officially RTM"), Volume Licence (VL) customers (7 August), TechNet subscribers (6 August) and developers with MSDN subscriptions (1 October) but I thought it wise to cut the quote off there for your sanity. It seems public beta and RC testers won't be getting the version so the aforementioned bittorrent will come into play.
Interestingly, LeBlanc also confirms that there will be a Windows 7 Family Pack that offers three licences but doesn't detail where it will be available ("select markets") or how much it will cost at this stage.
Everyone else remember 22 October is the global launch date for Windows 7 (or Windows 7 E as we'll have it in Europe) so not that long to go now...

The updated eight-core Mac Pro looks similar to previous models on the outside, but makes a number of internal changes that improve its digital-media and multitasking performance. Design professionals will welcome this new tool in their arsenal, although gamers might be slightly disappointed
What is it?
Professional-level desktop PC
What i think:
Great desktop, offering noticeable performance improvements and best-in-class design
I like:
Strong performance with high-definition video and 3D rendering, thanks to new Intel CPU and faster RAM
I don't like:
I wish it had eSATA ports for external hard-drive connections
The Mac Pro features four easy-to-remove hard-drive brackets
Apple has added few external features to the new Mac Pro. The only major difference is a pair of new video ports on the Nvidia GeForce GT 120 graphics card. Instead of a pair of standard DVI ports, as in the past, the new card now includes dual-link DVI and mini DisplayPort outputs. As before, you can add up to three more graphics cards to the Mac Pro for additional display support. Keep in mind that adding those cards will not get you increased 3D graphics performance via Nvidia's SLI or ATI's CrossFireX multi-GPU technologies.
The Mac Pro's interior is segmented into distinct zones for the various hardware components. The optical drives and power supply are concealed behind pull-out metal drawers, and, below, sits the familiar row of four removable hard-drive trays. Apple has preserved the cable-free hard-drive interface we came to love in the older Mac Pro in the new model. We've seen numerous Windows vendors imitate this design in the two years since its debut.
In addition, the expansion-card slots, CPUs and memory have also received improved design elements. Rather than relying on the various annoying retainer tabs common to PCI Express graphics slots on PC motherboards, Apple uses a single metal rod that spans across all four expansion slots to hold its cards in place. It's a simple solution to a problem you will only encounter when you add or remove an expansion card, but, given the price of the Mac Pro, we appreciate that the rod mechanism makes card upgrades that much easier.
You can slide the CPUs and memory out of the Mac Pro completely, thanks to its clever tray design.
As for the CPUs and memory, if you recall the older Mac Pro, you'll remember its memory attached to a unique removable tray that fitted into the motherboard like one large expansion card. Apple has taken that concept a step further in this new system, and now you can remove the entire CPU and memory portion of the motherboard via a simple tray design.
As with the expansion-card rod, this removable tray will really only benefit those who will make frequent upgrades or repairs to the Mac Pro. But I can't fault Apple for flexing its design muscle and providing its customers with the sense that the Mac Pro is as much a unique design object as a productivity tool. With Windows PC makers largely reliant on industry standards for motherboards and other components, few, if any, of Apple's competitors are as well-positioned to make such dramatic innovations to their own desktops.
Features
Apple has updated the Mac Pro's CPU, memory and graphics card. As with the older Mac Pro, the new model comes in either single-chip quad-core or dual-chip eight-core configurations, but Apple has now upgraded to Intel's Xeon 5500 chips, based on the Nehalem core shared by Intel's Core i7 consumer desktop chips.
With Nehalem come a few technology upgrades, specifically support for DDR3 memory and the return of Hyper-Threading Technology from the days of Intel's Pentium 4 chips. Hyper-Threading Technology can simulate more processing threads on the CPU, for up to 16 threads in total on our eight-core Mac Pro.
Aside from the processor and memory, Apple has also added a 512MB Nvidia GeForce GT 120 graphics card to the new Mac Pro's baseline spec, which amounts to a faster GPU and twice the graphics memory as the older ATI Radeon HD 2600 XT default card. You also get a 640GB hard drive this time around -- double the previous model's standard option.
Performance
Before I get into our performance tests, I should point out that my primary comparison for our eight-core default spec Mac Pro is the eight-core model from the previous generation. Because the new model's triple-channel memory needs to work in groups of three to take advantage of its full 1,066MHz bandwidth, I kept my review unit with its default 6GB of DDR3 RAM.
The older model, on the other hand, uses dual-channel DDR2 memory, and so it works fastest in multiples of two. Thus, I tested the older system with 4GB and 8GB to account for both higher and lower memory allotments in relation to the new 6GB system. Interestingly, I saw little difference between my 4GB and 8GB test results, but, since I have the scores, I might as well share what I found.

Firstly, it's important to note that the new CPUs' core 2.26GHz clock speed is significantly slower than the pair of 2.8GHz chips in the older model. This does not mean that the new Mac Pro is slow across the board, because it still has faster memory and a whole new CPU architecture with a more efficient cache structure.
But what it does mean is that, with applications that rely heavily on single-core processing speed, such as Photoshop, my review unit actually lagged behind both the 4GB and 8GB configurations of the older model. I should add that the less-expensive four-core version of the new Mac Pro has a single 2.66GHz quad-core chip, which could close the performance gap on these kinds of tests.

I found a much better outlook for the new eight-core Mac Pro with programs that rely on the strength of the system as a whole, such as Apple's Final Cut Studio 2, and in our multitasking and Cinebench tests, which split the work between multiple processing cores. Keep in mind that my comparison Mac Pros also have eight CPU cores, and a faster clock speed than the new model, but the new Mac Pro was able to overtake them on all of the above tests.

The gaming prospects of my Mac Pro review unit are less exciting. Yes, the 512MB GeForce GT 120 card provides a marked improvement in 3D performance compared with the older Mac Pros. But our Call of Duty 4 time-demo tests ran at a 1,680x1,050-pixel resolution and 4x anti-aliasing -- both relatively forgiving settings -- and the new Mac Pro was unable to hit an even 30 frames per second.
You can purchase a faster 3D card from Apple, but you'd have to pay a minimum of around £2,060 to upgrade even the less-expensive four-core Mac Pro. If gaming on a Mac is your goal, you still have to pay a disproportionate amount compared to a Windows desktop with the same level of 3D performance. The default graphics card will certainly let you dabble in 3D games, although you're better off with lower resolutions and image-quality settings, as well as less-demanding titles.
As I've said, my performance results apply only to the new eight-core Mac Pro in its default configuration. Apple offers various CPU, memory, hard-drive and other upgrades for both the four- and eight-core model.
As with Apple's new iMac, you can also buy the Mac Pro with a keyboard that has no numeric keypad, although the default configuration gets you the standard full-sized model. The Mac Pro also has no default wireless networking -- not a must-have in a traditional desktop -- but you can add an AirPort Extreme card for an extra £40. Other options include various mini DisplayPort adaptors, as well as different Fibre Channel PCI Express cards and professional software packages.
In addition to the video ports mentioned earlier, the new Mac Pro also gives you a handful of digital and analogue audio jacks, as well as USB 2.0 and FireWire 800 ports on the front and back. We'd still rather see Apple adopt the external eSATA standard for even faster external-hard-drive transfers than FireWire 800.
Conclusion
Design professionals should find the new eight-core Mac Pro a worthwhile purchase, thanks to multitasking and digital-media performance that's a marked improvement on that of previous models, as well as a number of useful design tweaks.
