Start up: fooling image algorithms, Xiaomi’s big year, how AMOLED screens degrade, and more


A thing of beauty – and an endangered species? Image by bozontee on Flickr.

A selection of 9 links for you. I’m not at CES, but if anything amazing happens there I might link to it through the week. (This doesn’t feel like an “amazing” year though. The last one to fit that description was probably 2011, when the Motorola Xoom and BlackBerry PlayBook made their first appearances. Ah, memories.)

Optical illusions that fool Google-style image recognition algorithms >> MIT Technology Review

A technique called deep learning has enabled Google and other companies to make breakthroughs  in getting computers to understand the content of photos. Now researchers at Cornell University and the University of Wyoming have shown how to make images that fool such software into seeing things that aren’t there.

The researchers can create images that appear to a human as scrambled nonsense or simple geometric patterns, but are identified by the software as an everyday object such as a school bus. The trick images offer new insight into the differences between how real brains and the simple simulated neurons used in deep learning process images.

In other words, this sort of thing:


How my mom got hacked >> NYTimes.com

Alina Simone’s mother had her computer encrypted by Cryptowall (essentially uncrackable), ransomed to $500 payable in Bitcoin – which wasn’t easy to sort:

it appeared her payment had arrived too late as well: By the time I got home from Greenpoint, her CryptoWall ransom had been raised to $1,000, and the $500 in Bitcoins she had deposited had vanished. In a panic, she wrote to Mike Hoats asking for advice. What he told her sounded crazy to me. Use the CryptoWall message interface to tell the criminals exactly what happened. Be honest, in other words.

So she did. She explained that the virus had struck the same week that a major snowstorm hit Massachusetts and the Thanksgiving holiday shut down the banks. She told them about the unexpected Bitcoin shortfall and about dispatching her daughter to the Coin Cafe A.T.M. at the 11th hour. She swore she had really, really tried not to miss their deadline. And then a weird thing happened: Her decryption key arrived.

When I shared the news with Mr. Hoats, he was jubilant. “That is great news, truly!” he wrote. “Whoever these yahoos are, they have some little shred of humanity.”

But Mr. Wisniewski had a more pragmatic take. “From what we can tell, they almost always honor what they say because they want word to get around that they’re trustworthy criminals who’ll give you your files back.”


Netflix cracks down on VPN and proxy “pirates” >> TorrentFreak

Netflix is starting to block subscribers who access its service using VPN services and other tools that bypass geolocation restrictions. The changes, which may also affect legitimate users, have been requested by the movie studios who want full control over what people can see in their respective countries.


Do AMOLED phone screens degrade over time? Yes, proof time, but… >> All About Windows Phone

Steve Litchfield wanted to find out whether the colour in AMOLED screens “washes out”:

I happen to have ended up with two Lumia 1020s – one is the workhorse that I’ve used almost every day for eighteen months, while the other is an AT&T model that doesn’t work on UK frequencies and so had hardly been used at all – just the odd test here and there. So, why not try looking at the same screens of content on both the ‘old’ 1020 and the ‘as new’ 1020? Would I be able to tell any difference?

Helping me were my family, who each voted on which screen looked clearer and crisper, without being told of the reason for the test or what they should be looking for. Each phone was set up with the same app, the same content and the same ‘Automatic’ brightness setting. Minor concerns were that the ‘old’ 1020 was on the Developer Preview programme and thus had a slightly newer version of the OS.

He took pictures and everything:

the very pentile nature of the 1020’s screen (and remember the same will be true for devices like the 925) means that a lot of the detail is being handled by the alternating red and blue sub-pixels, effectively edging the smartphone screen down from 768p to a very humble 384p.

18 months doesn’t seem like a long time.


Xiaomi confirms it sold 61m phones in 2014, has plans to expand to more countries >> TechCrunch

Xiaomi, the Chinese smartphone maker that raised $1.1bn last month, has confirmed that it sold 61.12m phones last year, bringing in an apparent revenues of 74.3bn CNY (US$12bn) in the process.

The new figures were released by CEO Lei Jun on Weibo and are right in line with the company’s expectation for the year. Xiaomi sold 18.7m devices in 2013, and 7.2m in 2012, so the four-year-old company is continuing to grow its business at a rapid rate — its recent funding round valued it at $45bn and it is now the world’s third largest smartphone maker.

Great! Although note that those numbers mean it sold fewer in calendar Q4 than Q3 (Ben Bajarin charted it here – from 18.1m to 17.1m. Why? No explanation given, but (you’d hope) the venture capitalist investors must have known when they piled in. Bajarin reckons (and it seems very likely) that they fell out of the world’s top five smartphone makers in Q4.

So where’s Xiaomi going? Into multiple smart devices – phones will quickly get played out – but I don’t see any chance of them coming to the US or Europe with a phone in 2015. They’d get fried over the intellectual property issues relating to smartphone patents, where they’ve already been burnt in India.


Mourn the death of the wallet – it holds memories as well as money >> The Guardian

Jess Carter-Morley (who is The Guardian’s fashion editor):

the wallet, that great talisman of adult life, is heading for extinction. As a day-to-day essential, it will die off with the generation who read print newspapers. Most of us, as children, played shops with Fisher Price tills, counting out the plastic coins and swapping them for plastic tomatoes. And we have grown up, and continued to do real shopping, in almost exactly the same way. But that kind of shopping – where you hand over notes and count out change in return – now happens only in the most minor of our retail encounters. Buying a bar of chocolate or a pint of milk, from a cornershop or a train station kiosk. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher up the scale you go. At the most cutting-edge retail flagships – Victoria Beckham on Dover Street, say, or Burberry on Regent Street – you don’t go and stand at any kind of till, when you decide to pay. The staff are equipped with iPads which they can whip out and use to take your payment while you relax on a sofa.

She has a very good point. Also, what will kids do shop-play with in a generation’s time? Will they wave their plastic phones over their plastic readers to say they’ve bought something?


46 times Vox totally fucked up a story >> Deadspin

The Gawker site takes the “we’ll explain the news to you and make it fun!” site to task, pointing out that it’s pretty hard to have people who are really experts in every field they write about. These ones particularly caught my eye (but there are 44 others):

9. Article Headline: Ignore age—define generations by the tech they use

Correction: This post originally gave incorrect dates for the introduction of radio and television technology and the invention of the cell phone. It also mis-labeled the web as the internet. We regret these errors.

10. Headline: The man who escaped both doomed Malaysian Airlines flights

Correction: Many of the key elements of Maarten de Jonge’s story have been disproven by subsequent reporting (particularly by Slate). There is no evidence that De Jonge actually booked a ticket on either flight. We’re sorry for repeating unverified claims.

Getting hoaxed is so dangerously easy for journalists online now. But some bring it on themselves. Now read on..

Peeling an onion: Phony iPhone 6 doom starts a chain reaction >> Macworld

2014 is over, but the Macalope is still cleaning up the mess from the crappiest New Year’s Eve party ever. Because as 2014 wound down, tech sites got wound up about some survey results.

“Here’s Proof That Samsung Owners Are Happier With Their Phones Than iPhone Owners” (indirect link and tip o’ the antlers to mylestaylor)

Business Insider‘s Julie Bort knows the score: It’s Samsung a billion and Apple zero. Or, well, 81 to 79, according to the American Customer Satisfaction Index.

The Macalope is great at this sort of riffing, but there’s a serious point here. As gets pointed out, Business Insider sourced this from Engadget, which sourced it from BGR, and yet none of them looked to see quite when the survey was carried out by ACSI. Turns out it was in May (you can see the unchanged scores – Samsung 81, Apple 79 – that are quoted).

There’s huge amounts of guesswork rolled into the BI piece and another at Hot Hardware (“#bendgate may have affected the scores”). All based on a survey from seven months ago.

And people wonder why “tech sites” didn’t get the Snowden leaks.


Two ‘Lizard Squad’ hackers arrested after Christmas DDoS attacks >> Hacker News

Vinnie Omari, an alleged member of Lizard Squad, arrested by the police investigating PayPal thefts and cyber-fraud offences occurred in 2013-14 while raiding his London home. Law enforcement officials reportedly seized phones, laptops and an Xbox from his home.

“The arrest is in connection with an ongoing investigation into cyber-fraud offences which took place between 2013 and August 2014 during which victims reported funds being stolen from their PayPal accounts,” Thames Valley police said in a press release.
Omari, who is a student of network security and ethical hacking, provided a copy of the search warrant to the Daily Dot, but the details have not been confirmed with local police yet. The press release from the Thames Valley Police Department confirms that Omari was arrested “on suspicion of fraud by false representation and Computer Misuse Act offences [sic].”

“They took everything… Xbox One, phones, laptops, computer USBs, etc.,” Omari said in an email to the Daily Dot, who broke the story.

The Federal Bureau of Investigation (FBI) is also reportedly investigating another Lizard Squad member named Julius “Ryan” Kivimaki a 17-year-old teenager, for his connection to the alleged DDoS attacks against Xbox Live and PlayStation Network. He was arrested by Finnish authorities later this week.

Tick, tock…


Start up: botnets worsen, who really hacked Sony?, mobile PCs in 2015, LizardSquad in detail

Botnet summary 2014 >> Spamhaus

To nobody’s surprise, botnet activity appears to be increasing. The majority of detected botnets are targeted at obtaining and exploiting banking and financial information. Botnet controllers (C&Cs) are hosted disproportionately on ISPs with understaffed abuse departments, inadequate abuse policies, or inefficient abuse detection and shutdown processes. Botnet C&C domains are registered disproportionately with registrars in locations that have lax laws or inadequate enforcement against cybercrime.

In 2014, Spamhaus detected 7,182 distinct IP addresses that hosted a botnet controller (Command & Control server – C&C). That is an increase of 525 (or 7.88%) botnet controllers over the number we detected in 2013. Those C&Cs were hosted on 1,183 different networks.

Depressing.


New York Times bets on native ads to drive mobile-ad revenue >> Media – Advertising Age

The New York Times is looking at native advertising, sponsorships and video to wring more money from readers coming to the Times on their mobile phones, according to Mark Thompson, president and CEO of The New York Times Co.

Just 10% of the Times’ digital advertising revenue was from mobile ads in the third quarter, but more than half its digital traffic came through mobile devices. Although mobile ad revenue is “growing rapidly,” this gap represents a “significant delta,” Mr. Thompson said at the UBS Global Media and Communications Conference in New York on Tuesday.

“It’s a challenge to overcome, but we will overcome it,” he said.

This seems like a natural and necessary evolution, given the low rates of mobile. They won’t make up for desktop, which in turn didn’t make up for print. Advertising rates are falling to zero.


What is going to happen >> AVC

Venture capitalist Fred Wilson with his list of predictions, from which we’ll pick these two:

4/ After a big year in 2014 with the Facebook acquisition of Oculus Rift, virtual reality will hit some headwinds. Oculus will struggle to ship their consumer version and competitive products will underwhelm. The virtual reality will eventually catch up to the virtual hype, but not in 2015.

5/ Another market where the reality will not live up to the hype is wearables. The Apple Watch will not be the homerun product that iPod, iPhone, and iPad have been. Not everyone will want to wear a computer on their wrist. Eventually, this market will be realized as the personal mesh/personal cloud, but the focus on wearables will be a bit of a headfake and take up a lot of time, energy, and money in 2015 with not a lot of results.

I’m very interested in trying Oculus Rift. Wearables are a tough sell anyway. However, Apple isn’t positioning its Watch as any part of what has gone before.


FBI briefed on alternate Sony hack theory >> Politico

Tal Kopan:

Researchers from the cyber intelligence company Norse have said their own investigation into the data on the Sony attack doesn’t point to North Korea at all and instead indicates some combination of a disgruntled employee and hackers for piracy groups is at fault.

The FBI says it is standing by its conclusions, but the security community says the agency has been open and receptive to help from the private sector throughout the Sony investigation.

Norse, one of the world’s leading cyber intelligence firms, has been researching the hack since it was made public just before Thanksgiving.

Norse’s senior vice president of market development said the quickness of the FBI’s conclusion that North Korea was responsible was a red flag.

1) a riled insider or insiders is a far, far more likely path to this hack
2) there’s no way in the world, now that the FBI has said that North Korea did it, and President Obama has echoed that, that the FBI or US government will ever admit to being wrong unless it is part of some gigantic diplomatic deal with North Korea. One has to wonder what NK would give the US in return for making the US eat humble pie in public.


Competition to intensify in flagging mobile PC market in 2015 >> TrendForce

Google’s low-cost Chromebook notebook computer performed well this year, benefiting from its cloud storage capacity and strong data security capabilities. But Chromebook sales were affected by Microsoft’s subsidized low-cost Windows notebooks. In 2014, Google sold about 6.5m Chromebooks and the device’s market penetration [of the mobile market] reached 4%. But if Chromebook uses the 2-in-1 PC concept, it will be difficult for Google to keep the device’s price low, Chen said. TrendForce forecasts Chomebook sales will increase slightly to 8m units in 2015. 

This year, Microsoft and Intel both launched subsidy plans for their notebooks and tablets, which had reduced their revenues. “Because they lower manufacturers’ costs, subsidies indirectly benefit consumers, but it will be better if Microsoft and Intel can find more substantial ways to develop the market, such as by utilizing the 2-in-1 concept or cloud computing,” [Caroline] Chen [Trendforce notebook analyst] said. 

Notably, this group describes the expected 12.9in iPad as a “2-in-1” device, not a tablet. There’s a certain amount of disagreement between analyst companies on what is a PC, what’s mobile, what’s a 2-in-1, and what’s a tablet; it can make decoding what they say really tricky.


May 2014: Samsung says new Galaxy S5 smartphone is off to a strong start >> WSJ

Noted here for its hindsight value, from an interview in May 2014:

J.K. Shin, who also heads Samsung’s mobile business, said in an interview at company headquarters that sales of the new smartphone reached more than 11m units since its launch in early April, outpacing the Galaxy S4, which sold about 10m in the first month after it was unveiled last year.

Speaking halfway into Samsung’s second quarter, Mr. Shin also said he thinks strong Galaxy S5 sales will lead to higher mobile profit margins and market share in the quarter. He declined to provide specific figures.

“It’s been a month since we began selling the S5, and out of the gate, sales are much stronger than the Galaxy S4,” Mr. Shin said, noting sales were especially good in developed markets such as the U.S., Australia and Germany.

The comments from the top executive at the world’s biggest smartphone maker paint a rosier picture of Samsung’s mobile business than many analysts and investors had been expecting.

What then happened is that Samsung made 20% more S5s than it had S4s, but sold 10% fewer. This meant oversupply in the channel (wholesalers/carriers) and forced price cuts, and so lower profits and slower sales.

Worth considering when you next see a chief executive interviewed, and weigh up what analysts are expecting.

Samsung Electronics should announce its preliminary 4Q results some time next week.


Here’s why The Hunt’s app developer hearts Android >> VentureBeat | Dev | by Barry Levine

While “the conventional wisdom is build first for iOS,” he said, “if we had to do it all over again, I would launch on Android first,” or at the same time as iOS. More than half of The Hunt’s downloads are to Android devices.

The Hunt’s Android version launched last month, and its iOS version came out last year.

The Hunt allows its three million, mostly female users to post a picture of some product they’ve seen online — such as a photo of a dress in a news story — and get feedback from the community of retailers and fellow shoppers about where that item or something similar is sold.

Weingarten noted that his company has “a very successful iPhone app, [with] thousands of daily downloads.”

“I’m not being negative about Apple.”

But, he pointed out, his company is “seeing much stronger engagement rates on Android.”

As one example, more than a third of Android users who have downloaded the app have started Hunts, while only 20% of iOS users have. Additionally, 40% of iOS weekly users are following to see if their Hunt queries have found the product in question, while half of Android users are.

Be good to know some more of the demographics of the users showing these behaviours. An interesting data point though.


Inadvertent algorithmic cruelty >> Eric Meyer

Yes, my year looked like that.  True enough.  My year looked like the now-absent face of my little girl.  It was still unkind to remind me so forcefully.

And I know, of course, that this is not a deliberate assault.  This inadvertent algorithmic cruelty is the result of code that works in the overwhelming majority of cases, reminding people of the awesomeness of their years, showing them selfies at a party or whale spouts from sailing boats or the marina outside their vacation house.

But for those of us who lived through the death of loved ones, or spent extended time in the hospital, or were hit by divorce or losing a job or any one of a hundred crises, we might not want another look at this past year.

To show me Rebecca’s face and say “Here’s what your year looked like!” is jarring.  It feels wrong, and coming from an actual person, it would be wrong.  Coming from code, it’s just unfortunate.  These are hard, hard problems.  It isn’t easy to programmatically figure out if a picture has a ton of Likes because it’s hilarious, astounding, or heartbreaking.

This post has been widely shared, but it is worth reflecting on from a distance. Algorithms have dangerous power because once we start them off, it’s really hard to stop them.


Lizard Squad kids: a long trail of fail >> Krebs on Security

In a show of just how little this group knows about actual hacking and coding, the source code for the service appears to have been lifted in its entirety from titaniumstresser, another, more established DDoS-for-hire booter service. In fact, these Lizard geniuses are so inexperienced at coding that they inadvertently exposed information about all of their 1,700+ registered users (more on this in a moment).

These two services, like most booters, are hidden behind CloudFlare, a content distribution service that lets sites obscure their true Internet address. In case anyone cares, Lizardstresser’s real Internet address currently is 217.71.50.57, at a hosting facility in Bosnia.

In any database of leaked forum or service usernames, it is usually safe to say that the usernames which show up first in the list are the administrators and/or creators of the site. The usernames exposed by the coding and authentication weaknesses in LizardStresser show that the first few registered users are “anti” and “antichrist.” As far as I can tell, these two users are the same guy: A ne’er-do-well who has previously sold access to his personal DDoS-for-hire service on Darkode — a notorious English-language cybercrime forum that I have profiled extensively on this blog.

One of the duo alleged to make up Lizard Squad is a 22-year-old Briton who has been arrested and bailed by Thames Valley Police. He’s on Twitter, has been interviewed by Sky News, and denies having taken part in any hack (or DDOS?) of Sony or Microsoft; he claims just to be the group’s spokesman, if his Twitter feed reflects his views.

Let’s see how that works out. He also says the alleged offences for which he has been bailed include some from 2013.
