Apple Confirms iOS Backdoors, But Calls Them “Diagnostic Capabilities”

Apple acknowledged that its iOS operating system for iPhones and iPads contains several previously undisclosed “diagnostic capabilities”—services that an iOS forensics expert recently described as “backdoors” that could allow broad access to a user’s personal data on those devices under certain circumstances.

The issue involves problematic iOS services identified several months ago by Jonathan Zdziarski, the forensics expert who is also a one-time iOS jailbreaker and the author of several books on iPhone development. Zdziarski gave a presentation on his findings last weekend and published the slide deck to his talk, which drew wider attention to his findings. (See our FAQ about Zdziarski’s backdoor findings here.)

Through The Backdoor

The three backdoors Zdziarski highlighted in his talk are present in 600 million iPhones and iPads, and are capable of accessing a great deal of personal information and then dumping it off the phone to a “trusted” device, such as the desktop computers many iPhone users plug their devices into. The backdoors can only be accessed via such trusted devices, limiting the danger of exploit—although that trust mechanism itself could also be spoofed by a determined attacker.

Until last night, Apple had apparently never described these iOS services publicly. Zdziarski reported the services do not notify users when they begin accessing personal data; do not require the consent of users if they access personal data; and cannot be turned off by users.

In a support document released Tuesday night, Apple described the three backdoors as “diagnostic capabilities to help enterprise IT departments, developers, and AppleCare troubleshoot issues” and offered a few details about each:

1. com.apple.mobile.pcapd

pcapd supports diagnostic packet capture from an iOS device to a trusted computer. This is useful for troubleshooting and diagnosing issues with apps on the device as well as enterprise VPN connections. You can find more information at developer.apple.com/library/ios/qa/qa1176.

2. com.apple.mobile.file_relay

file_relay supports limited copying of diagnostic data from a device. This service is separate from user-generated backups, does not have access to all data on the device, and respects iOS Data Protection. Apple engineering uses file_relay on internal devices to qualify customer configurations. AppleCare, with user consent, can also use this tool to gather relevant diagnostic data from users’ devices.

3. com.apple.mobile.house_arrest

house_arrest is used by iTunes to transfer documents to and from an iOS device for apps that support this functionality. This is also used by Xcode to assist in the transfer of test data to a device while an app is in development.

Apple’s support document acknowledges that a third party can access these services wirelessly via Wi-Fi from a trusted device, as Zdziarski had previously reported. It neither confirms nor denies Zdziarski’s finding that these three services operate without the knowledge or explicit consent of the user.

Apple also claims a much more limited role for the file_relay service than Zdziarski found, saying it is used only for “limited copying  of diagnostic data from a device.” Zdziarski, by contrast, reported that file_relay has access to 44 data sources within an iPhone, including highly personal information as call records, SMS text messages, voicemail, GPS logs and more. Such personal information has little in common with diagnostic data in most cases.

In a blog post reply, Zdziarski criticized Apple for being “completely misleading” in some of its descriptions and for failing to address his other concerns such as user consent and notification. But he also acknowledged that Apple will probably begin fixing those issues behind the scenes:

All the while that Apple is downplaying it, I suspect they’ll also quietly fix many of the issues I’ve raised in future versions. At least I hope so. It would be wildly irresponsible for Apple not to address these issues, especially now that the public knows about them.

(Zdziarski’s blog is having server problems; here’s a cached version of his reply to Apple should you need it.)

I’ve asked Apple for further clarification, and will update if and when I hear back from the company.

Netflix Calls Out Verizon For Charging For Crappy Streaming, Part Deux

Netflix knows sure knows how to get a rise out of Internet service providers: Since mid-May, the streaming video service has been posting an error notice to Verizon subscribers blaming the network for slow delivery of its online videos. Verizon issued a cease-and-desist order and demanded lists of Netflix customers who might have seen this message.

The streaming provider’s response? Don’t blame us for your crappy network.

The letter from Netflix General Counsel David Hyman (.PDF) starts out cordially enough:

Your interpretation mischaracterizes our messaging. The message you cite to in your letter merely lets our consumers know that the Verizon network is crowded.… The message is part of our ongoing transparency efforts.

Basically, Netflix said that the error message was merely part of a transparency test, which is set to end June 16. Whether that was always the plan or merely a last-minute decision to (somewhat) appease the ISP isn’t clear, though it’s very likely the latter.

Still, Netflix couldn’t resist throwing in a few barbs:

In fact, it is my understanding that Verizon actually upsells customers to higher speed packages based on improved access to video services, including Netflix…. To ensure that these customers get the level of service they pay you for, it is your responsibility to make sure your network, including your interconnection points, have sufficient capacity to accommodate the data requests made by those customers.

Translation: You’re charging people for service you aren’t providing, and somehow calling Netflix on that? That’s just not cool.

Then things took a turn for the hilarious.

To try to shift blame to us for performance issues arising from interconnection congestion is like blaming drivers on a bridge for traffic jams when you’re the one who decided to leave three lanes closed during rush hour.

In addition, the streaming company criticized Verizon’s refusal to join Open Connect, the peering and caching program Netflix established to allow ISPs to connect right to the service directly instead of going through third-party content delivery networks. Participants include Frontier, British Telecom, TDC, Clearwire, Telus, Bell Canada, Virgin, Cablevision, Google Fiber and others. Notably Verizon and Comcast are both missing from the list. 

You have chosen not to participate in the Open Connect Program, but instead have allowed your network connection to Netflix to degrade until we agreed to pay for augmented interconnection. We brought the data right to your doorstep…all you had to do was open your door. 

Meanwhile, Netflix flatly ignored Verizon’s demand for the subscriber list. No word yet on the broadband provider’s next course of action, but we’re getting the popcorn ready for the next act in this little play. Because it’s quite likely that Verizon’s rebuttal will be swift and fierce. Unfortunately, as the drama continues on, viewers are the ones who are losing.

With OS X Yosemite, You Can Send And Receive Texts And Phone Calls From Your Mac


 

Today Apple announced OS X Yosemite, the latest version of its Mac software. The developer preview is available today, and it will be released free to everyone in the fall.  

One of the biggest changes affects how iPhone users send and receive text messages from users who don’t have iMessage, as well as changing how users can make and receive phone calls.

With OS X Yosemite, users will be able to send and receive text messages and phone calls directly from their Macs.

Historically, iPhone users have only been able to make and receive text messages and phone calls direct from their iPhones—text messages from Android or Windows devices are shown in green text bubbles, whereas iMessages from iPhones, iPads and Macs appear as blue text bubbles. iMessages travel to Macs, while ordinary SMS text messages haven’t to date. This update changes that, bringing all text messages to Apple’s desktop systems.

“Green bubble friends, they have inferior devices,” senior vice president of Software Engineering Craig Federighi said on stage at WWDC when he announced the new text and phone call features. The audience—largely composed of Apple developers inclined to think well of the company’s products—broke out in applause and laughter.

Not laughing: Users who have switched from iPhones to Android smartphones, only to find their text messages have gone missing. It’s not clear if Apple’s latest updates do anything for people in that situation.

Meet VoLTE, The Future Of Phone Calls

If you haven’t already, soon you’re going to be hearing a lot about a new standard for making mobile phone calls: VoLTE. It stands for “voice over LTE,” but what it really means is that before long, your voice calls are going to be transmitted across the airwaves using the same technology the Internet pioneered for data. 

VoLTE, an acronym sure to be coming soon to a mobile-phone advertisement near you, promises two immediate potential benefits to consumers: clearer calls with fewer dropouts and the ability to use voice and data services simultaneously (which some, but not all, carriers offer already). For the carriers, it means more efficient use of their allocated radio spectrum, meaning they can serve more customers without additional network investments.

(What VoLTE almost certainly won’t do is lower your phone bill, as carriers have a habit of charging more for network improvements that actually save them money.)

To understand how VoLTE is supposed to manage all these improvements, you have to understand why traditional LTE couldn’t carry voice.

Circuit Switched Vs. Packet Switched

LTE is the current gold standard for mobile data (it stands for “long term evolution”), although you may know it better as “4G.” LTE makes it possible to download or stream Internet video far faster than its predecessor 3G networks—but as it stands, LTE doesn’t carry voice calls. Instead, carriers with LTE fall back to older 2G and 3G networks for calls.

Voice over LTE will change that.

LTE’s speed advantage stems from the way it handles data. 3G network standards like UMTS and CDMA basically open a dedicated channel between nodes to handle voice, text and data, a technique called “circuit switching.” This is a simple, but fairly expensive practice in network terms; it’s as if you got a dedicated lane for your morning commute that no one else could use. Great for you; terrible for everyone else.

LTE, by contrast, is based on an Internet technology called packet switching. In such networks, a sender divides up any sort of data—email, Web pages, a Netflix stream—into small packets of equal size, each of which carries an “address label” bearing its ultimate destination. The sender tosses these packets onto the network, where they’re directed toward their destination at every juncture, or “node.” They ultimately all meet up at their destination, where they’re reassembled and delivered to the recipient.

This is a lot more like your actual morning commute, in which you have to share the road with everyone else heading somewhere. Like your commute, packet switching sounds a bit haphazard, and it can be—but it’s also a fantastically efficient, flexible and robust way of transmitting information. Until now, though, it wasn’t any use for mobile voice calls, which still require circuits (and circuit switching).

When LTE debuted in the U.S., carriers had to figure out how to make voice calls work while pushing out 4G smartphones to customers. Most carriers adopted a stopgap measure called “circuit-switch fallback” in which LTE handles all data connections, but phones call back to the 3G network when you make a call. VoLTE effectively obsoletes this hybrid technology.

VoIP vs. VoLTE

You might look at your smartphone and say, “Hey, I can already make voice calls over my data connection! I have Skype and Google Hangouts!” It is true, you can indeed make voice calls using your data connection with these apps, which are referred in the cellular industry as “over-the-top” (OTT) services because they supersede a carrier’s own voice and messaging services.

You may be using LTE to make voice calls with these apps, but you’re not using VoLTE. Services like Skype, Hangouts, WebEx or Fuze are what is called Voice Over Internet Protocol—VoIP. These services work on your 3G or 4G LTE devices because they use your data connection through the Internet, not the traditional voice network from the carriers.

As U.S. cellular carriers networks evolve, VoLTE will compete with more directly with OTT services like Skype.

Benefits Of VoLTE

T-Mobile is one of the first cellular carriers in the United States to institute VoLTE phone calls on a limited range of smartphones, starting in Seattle. In an announcement last week, T-Mobile chief technology officer Neville Ray described the technology behind the company’s VoLTE offering:

If you’re like me and love digging into the underlying science, here’s how it works. (If this doesn’t interest you, feel free to skip this bit.) VoLTE calls will be carried over IP [Internet protocol, or packet switching] on our LTE network instead of a circuit-switched path on our 4G HSPA+ network. This is advantageous because your phone stays on our wicked fast LTE network to make a call. The tricky bit in all this is the smooth mobility between our various radio layers. Enhanced Single Radio Voice Call Continuity (eSRVCC) is a new LTE Advanced function and we’re excited to be the first to deploy it in the U.S. All of this basically helps ensure that your capable phone won’t drop a call if you leave an LTE area and it switches to 4G HSPA+ or 2G coverage.

Technologies like Enhanced Single Radio Voice Call Continuity are fancy terms used to described the central tenet of VoLTE. For the first time, voice and data will be living together in harmony on the same radio layer, meaning that smartphones won’t need to displace back to 3G or a different spectrum frequency to handle both capabilities.

What this means is that, as LTE is expanded in the U.S., old 3G networks like CDMA or HSPA+ will wither away. Verizon said last year that it will begin phasing out its 3G network at the start of 2014 and other U.S. carriers are planning similar rollbacks. The future of voice and data in the U.S. is LTE (and future advancements, like LTE Advanced), and carriers see no need to maintain costly old infrastructure.

The cellular operators are just starting their marketing campaigns around the evolution of LTE. T-Mobile claims what it calls “HD Voice” (clear voice calls over cellular) and Verizon claims to be rolling out what it calls XLTE, which is basically just extra spectrum for its existing LTE network to operate. Sprint’s Spark network isn’t an advance of LTE either, just a new mode of how it aggregates its various spectrum and varieties of LTE (TD-LTE and FD-LTE) into a more efficient package than its previous 4G offerings. 

Smartphone manufacturers will benefit by the ability to trim how many radio receivers they place in smartphones. Instead of needing to support disparate networks with a variety of chipsets, they can just rollout phones with chipsets directed at specific carrier spectrum requirements. 

For consumers, the benefit is harder to see. VoLTE will fix the unwelcome problem of not being able to use voice and data on a phone at the same time for some carriers, and calls may be clearer and less prone to be dropped going forward. VoLTE is an important evolutionary step in mobile computing, but it’s still possible that many consumers will hardly notice the change.

Hey Google Hangouts, Skype Now Offers Free Screen Sharing And Group Calls, Too

Skype is liberating group calls and screen sharing for all users, which are two powerful additions that should please businesspeople and enterprises everywhere.

Group calls had long been available to Skype Premium customers on Mac, Windows and even Xbox One, but now it’s rolling out to anyone using those systems—free of charge.

Microsoft GM of consumer marketing Phillip Snalune said free group calls will eventually roll out to people using mobile devices and other systems, but for now, it’s just available for Windows, Mac and Xbox One users. It’s a solid start, however, especially when you consider Microsoft was likely feeling pressure from Google Hangouts, which is also free, but doesn’t need to be downloaded like Skype. Of course, Google Hangouts also works on mobile devices, which Skype is still working on.

Skype also made screen sharing free for all group video calls, which is a key for businesses that collaborate remotely. So even as it looks to compete against popular consumer-oriented tools like Google Hangouts, Skype’s focus on appeasing the enterprise shows that Microsoft still knows where its bread is buttered.
