Talking SIM cards, spooks and hacks on The World Today

ABC logoOn Friday, The Intercept published some astounding claims under the headline The Great SIM Heist: How spies stole the keys to the encryption castle. The story claims that Five Eyes spooks had achieved a major breakthrough in their ability to monitor mobile communications.

American and British spies hacked into the internal computer network of the largest manufacturer of SIM cards in the world, stealing encryption keys used to protect the privacy of cellphone communications across the globe, according to top-secret documents provided to The Intercept by National Security Agency whistleblower Edward Snowden…

With these stolen encryption keys, intelligence agencies can monitor mobile communications without seeking or receiving approval from telecom companies and foreign governments. Possessing the keys also sidesteps the need to get a warrant or a wiretap, while leaving no trace on the wireless provider’s network that the communications were intercepted. Bulk key theft additionally enables the intelligence agencies to unlock any previously encrypted communications they had already intercepted, but did not yet have the ability to decrypt.

The company in question is Gemalto. With headquarters in Amsterdam, and 28 “personalisation facilities” around the world that burn the encryption keys into SIM cards, it has nearly 30% of the market — making it an obvious target for spooks.

The story started to filter through to the mainstream media on Monday in the US, or Tuesday Australian time, and I’ve already done two radio spots on the topic — and doubtless there’ll be more to come.

The first spot was an interview for ABC Radio, and parts of it ended up in this report on The World Today.

[The three Australian mobile network operators] Telstra, Vodafone and Optus have all confirmed that Gemalto has supplied their SIM cards. Sarah Sedghi reports.

This is the full five-minute report.

Talking Telstra wholesale pricing on 1395 FIVEaa

FIVEaa logoTelstra is Australia’s biggest telco, and owner of the vast majority of the copper customer access network (CAN), the so called “last mile” — and it wants to raise its wholesale prices, charging other telcos 7.2% more.

“The move would affect almost every Australian with a phone line or an internet connection, because Telstra owns most of the copper phone lines that other telcos depend on to service their customers,” reported ABC News.

“The company leases about 4 million line services to rivals and has not raised wholesale prices since 2011.”

On Wednesday I spoke about the distinction between retail and wholesale telecommunications providers, and whether a 7.2% rise is reasonable, with Will Goodings on 1395 FIVEaa — after independent Senator Nick Xenophon has given his views.

Xenophon thought the rise was unreasonable, because Telstra had “gotten $11 billion” from NBN Co. I disagreed on both counts.

For reference, here’s the current Telstra Wholesale rate card (PDF).

Weekly Wrap 185: A post-productivity period, primarily

Poster for iloveshopping24hrs.com: click to embiggenHere’s the key stuff that happened in my week of Monday 16 to Sunday 22 December 2013. Like last week, it wasn’t nearly as productive as I wanted it to be.

Articles

Media Appearances

None.

Corporate Largesse

None. I’m guessing that all the corporate types had stopped worrying about the clients and started worrying about their own end-of-year parties.

The Week Ahead

Well Monday has already happened, and it wasn’t very productive. Tuesday is just beginning, and it’s full of errands in and around the Sydney CBD. It’s also Christmas Eve, so once those errands are done I’ll be turning down the productivity dial even further for the rest of the week.

I may write a couple things over the remainder of the week, or I may not. It’ll all depend upon how I feel at the time.

Why are corporations so paranoid, Telstra?

Telstra screenshot: click to embiggenWith all their constant worrying about whether people would recommend them or not, like this example from Telstra, I’m starting to think that most big corporations are paranoid psychotics — and not in a good way.

The other day I conducted a perfectly routine transaction at a Telstra Shop. I cancelled a mobile broadband service and replaced it with a different one. As with many businesses, my visit was followed up with a brief survey, “Please tell us how you feel.”

There were four questions, but none of them actually asked me how I felt:

Is your new Telstra service working? If you answer ‘no’ to this question, we will present you with options to get in contact with Telstra to resolve your issue on the next page.

OK, that’s fair enough. You need to know that the customer has a working broadband service. But the other three?

When you consider all aspects of buying and connecting your service — how likely are you to recommend Telstra to a friend or colleague?

Thinking about your in-store experience, how likely would you be to recommend the store to a friend or colleague?

What are the most important reasons why you gave us this score?

Guys, this goes way beyond “Does my bum look fat in this?” This is self-obsession. “What are you going to tell people about us? Why, what did I do?”

These constant questions about likelihood of being recommended are a sign of paranoia. I don’t care how you feel, I gave you money. Recommending you or not just isn’t a KPI for me.

How about you ask questions that reflect the customer’s needs and aspirations? Or even just concrete questions about how long I had to wait, whether staff were polite, or whether the service meets my needs?

Weekly Wrap 165: Distractions and decisions, of a sort

HMAS Advance (P83): click to embiggenIf there was a unifying theme for my week Monday 29 July to Sunday 4 August 2013, it was Distraction.

I distracted myself with the Nokia Lumia 925 / Windows Phone 8 trial. While I’m getting some useful real-world experience of the two products, it’s probably not going to generate any revenue, and it soaked up a lot of my time. I distracted myself even further by fiddling around with video editing.

I was distracted by delayed trains on Thursday night, sadly due to a death on the railway line at Mt Druitt, which meant I didn’t get back to Wentworth Falls until 0100 the following day.

I was distracted by Telstra’s changes to mobile broadband allowances — apparently they’ve now dropped the maximum data allowance they’ll provision to a mobile phone to a mere 9GB a month, so I was living the scenario I wrote about recently — and I had to trek to Penrith on Saturday to buy another device or risk being sodomised by their 10c/megabyte over-run charges.

And finally, today I was distracted by Prime Minister Kevin Rudd finally deciding to call the election for 7 September — which means I’m distracting myself even more.

The Week Ahead

[Update Monday 5 August 2013, 2155 AEST: This section has been changed to reflect the unfolding reality.]

On Monday I’ll write a ZDNet Australia column, making up for the one I’d intended to write on Friday, and then rum some errands to Katoomba.

On Tuesday I’ll write for Technology Spectator, work on revenue-generation for The 9pm Election, and complete episode 3 of the Corrupted Nerds: Conversations podcast, amongst other things.

On Wednesday I’ll head to Sydney for some of the Check Point Experience, an event hosted by security vendor Check Point. Thursday will be another Sydney trip for a medical appointment and a few other bits and pieces. And Friday will be a day of podcast production,I hope.

The weekend is currently unplanned.

Vodafone Australia’s new 4G network ain’t bad

Vodafone logoFor the last few week’s I’ve been using Vodafone Australia’s new 4G network, and I must say it ain’t bad at all. Here’s quite a long post about what I’ve experienced.

Since Saturday 8 June 2013 — that is, since about a week before the network was launched to the public — I’ve used Vodafone’s network as my primary data link to the internet, via a Samsung Galaxy S IV 4G handset that Vodafone loaned me, along with a SIM that gave me uncapped data. Generally I used that smartphone as a Wi-Fi hotspot for my everyday internet use.

Normally I use Telstra’s Next G 4G network — or their 3G network outside 4G coverage areas. The hardware is either a Sierra Wireless pocket Wi-Fi hotspot, or sometimes my Samsung Galaxy S III 4G handset configured as a Wi-Fi hotspot. So what you’re about to read is, I think, a reasonable comparison.

That said, I’d call this a “trial”, not a “test”. I was not rigorous at all about this, and the results only reflect what I experienced on the days in question. Your mileage may vary.

Key Observations

  1. I often work on the train between Sydney and the Blue Mountains. So, on Saturday 8 June, I did a side-by-side comparison. With all other data usage removed from the handsets, I did speed tests as speedtest.net as they sat on my lap. On the train. The detailed results are over the fold. As you’ll see, Vodafone’s network was often faster than Telstra’s, especially where Telstra was likely to suffer congestion. This is unsurprising: there weren’t any customers on Vodafone’s network yet.
  2. Over the three weeks of the trial, my general impression was that where both Vodafone and Telstra had 4G coverage, they offered similar speeds. In highly congested locations, such as the Sydney CBD, North Sydney or Newtown, Vodafone often pulled ahead. But Vodafone obviously has far less geographic coverage for now. See below for the maps.
  3. Up at my Blue Mountains base near Wentworth Falls, neither Vodafone nor Telstra had 4G coverage, only 3G. While I didn’t do speed tests there, as a user I found no noticeable difference between the two networks. That is, there were no occasions when I felt the urge to whinge that Vodafone’s network was causing me more problems that Telstra’s usually did. Both seemed to have the same difficulty punching a signal through a eucalypt forest that’s waving in the wind. That’s not Science, obviously, but it says… something. Probably that there’s not much to choose between the two networks in that location, given the sort of things I do.
  4. On my regular train runs up and down the mountains, there was no real experiential difference between Vodafone’s network and Telstra’s — except, of course, where Vodafone has no 4G. Apart from one factor, that is. My impression was that the Telstra handset was better at noticing when 4G became available and switching to that, whereas the one on Vodafone would stay on 3G all the way into Central even though there’s plenty of 4G areas — but I didn’t test this properly.
  5. Using mobile broadband is a very different experience when you’re not worried about how many gigabytes of data you’re sucking down. As I wrote the other week, the promise of mobile broadband is years away.

Overall, it would appear that Vodafone is rolling out a 4G network that will match Telstra’s in terms of performance, at least once the coverage is in place. Assuming there’s coverage where you need it, the choice will come down to the pricing and support, as always. Whether this will be enough for Vodafone to win back the customers they’ve lost is another question.
