In today’s Metro I investigate whether the CIA really can ‘hackcess all areas’. Plus, I ask if wearable tech has fallen from fashion. Hold on tight, it’s time to Connect…
Last week’s WikiLeaks document dump professes to reveal how the CIA has – with help from agencies including MI5 – been collecting and developing an arsenal of hacking tools, exploits and cyber skeleton keys to pick its way into the devices we use every day.
We shouldn’t be surprised. Covert surveillance is a tool widely used by intelligence agencies to maintain national security and counter terrorism.
But if the good guys can find a backdoor into our connected kit, surely the bad guys can too? Read on in the Metro e-edition…
The Apple Watch launched less than two years ago. I know this because on the day of the launch I confidently declared that ‘wearable tech is the next big thing’ on stage at the Gadget Show Live, enthusing about the upcoming Pebble Time smartwatch and the latest Jawbone and Fitbit gear.
How times change.
Less than two years on and the wearables phenomenon has failed to catch on, leading analysts to rein in their optimism.
Back to the Apple Watch.
Many – myself included – saw the launch of Apple’s highly-anticipated wearable as a watershed moment. Indeed it was, but rather than sparking a wearables revolution it had the opposite effect. ‘Oh, is that it?’, was the consensus.
However, as Bill Gates once quipped, we tend to over-estimate the impact of a technology in its first two years but underestimate its impact in ten. It might be in the depths of the trough of disillusionment but I can’t see anything other than wearable tech to playing a huge part in our future.
My feature on how to secure your Amazon Echo was published in TechRadar last week. Here is my take on why securing these intelligent home hubs is of vital importance.
Buttons are obsolete. Simply by conversing with my Alexa I can control my central heating and the lighting around my house and garden; I can buy products with my voice, check my personal calendar, set alarms or reminders, update my things to do list, read my favourite book or play any song, album or playlist on Spotify. With my voice.
Hear no Evil
The convenience this offers is staggering and, in a little over three months since I plugged it in and powered it on, my Amazon Echo has already changed many behaviours in our household. For the better? I think so. However…
With convenience comes compromise, especially when it comes to security. We should never be blinded by the utility of any new piece of technology.
I made one mistake in extolling the virtues of our Amazon Echo above. You see, all of these amazing things and more can be commanded not only with my voice, they can be asked by anybody’s voice.
Voice Recognition versus Speech Recognition
While Alexa has enviable speech recognition – the ability to understand and interpret natural language input by speech – she has yet to learn the skill of voice recognition. Often confused, voice recognition is the ability to uniquely distinguish between different people’s voices by analysing physical and behavioural characteristics.
With voice recognition Alexa would know whether it was me (ie authorised) ordering that Nintendo Switch console from Amazon Prime, or if it was my Mario Kart-loving daughter trying her luck (sorry, denied). Did I just ask Alexa for a 2am alarm call or was somebody outside my living room window attempting to play a prank?
Amazon has no plans to introduce voice recognition into the Amazon Echo just yet. Nevertheless, there are steps that Echo owners can take to make sure they enjoy the convenience of a virtual assistant without the worry of being woken up by a 2am prank alarm call.

On BBC Watchdog tonight I appear in an item highlighting gaping holes in home food delivery service Deliveroo’s security and fraud prevention systems.
Victims of so-called ‘Deliveroo fraud’ report having their credit and debit cards emptied of many hundreds of pounds on food and drink orders they never placed, to addresses many hundreds of miles from where they live.
Deliveroo’s standard response to claims of a security breach has left those affected with a bitter taste in their mouths, suggesting victims look to their own security failings instead.
The first a victim knows of the fraud is when they receive an email from Deliveroo confirming an order has been placed.
Deliveroo insists that its own systems have not been the subject of a hack or data breach; instead the firm advises that customers should not reuse passwords and usernames across multiple online accounts.
Sound advice on its own, but a critical mass of Deliveroo victims all suffering the same fraud might suggest that Deliveroo should look again at its own security measures.
- Smart fraud prevention mechanisms, if present at all, appear to be ineffectual here. Purchases that are so out of character – such as those highlighted in the show – should easily be picked up by automated systems and subjected to additional verification.
- Similarly, a change of delivery address should also trigger additional verification – a PIN sent to the account holder’s smartphone, for example.
- Deliveroo chooses not to authenticate customer card payments with a CVV2 code.
The Card Verification Value is one of the names given for the additional security numbers printed on the signature strip or from of the card. Deliveroo is far from the only retailer to forego ‘card not present’ security – Amazon, with its 1-click purchase is another. However, this lack of verification allows fraudsters to place orders on credit cards that are not theirs with no challenge at all.
Deliveroo’s light touch on security can be put down to one thing: sales. Here’s how skimping on security benefits Deliveroo’s bottom line:
- When we buy something, the more hoops we have to jump through to make that purchase, the more likely we’ll drop out and go somewhere else.
- Understandably Deliveroo wants to make placing an order with them as simple a process as possible by cutting out as many hoops as it can.
- However, some of those hoops are there for reasons of security; in removing those, Deliveroo is not only making it easier for its customers to place an order, it’s making it easier for them to be defrauded.
Watchdog airs on BBC1 tonight at 8pm.
The new series of Rip Off Britain begins this Monday on BBC1 resuming its mission to expose shams, scams and poor customer service.
In this series I look at how failures in Vodafone’s billing systems and customer services have left subscribers out of pocket and with costly black marks on their credit history; also I investigate how freely available information might be used by identity thieves to build up detailed profiles of their victims.
One item that I hope to be covering more of is the future of passwords.
Like a stuck record, over the last four or so seasons on Rip Off Britain I’ve made the point again and again about the importance of good password hygiene to minimise the risk of hacks.
But recent developments in voice biometrics technology might be part of a move to make our live online much safer. In fact, customers of some major UK banks and service providers are already using just their voices to securely log-in to their online accounts.
The software claims to analyse around one hundred different behavioural and physical characteristics of our voices (for example accent or length of vocal folds) and is being used by customers of TalkTalk and HSBC among others. Its developer, Nuance, says the technology is so sophisticated that it can even distinguish between identical twins.
We took a special version of the voice recognition app to the BBC pop up shop at the Trafford Centre in Manchester to discover whether shoppers there felt secure using their voice as their password.
Rip Off Britain airs on BBC1 Monday to Friday from 12th September at 9.15am.
A lot of my work right now is around cyber crime and cyber safety. My Hackageddon feature this week’s Connect section in The Metro illustrates some ways in which our online data might be vulnerable.
While there are precautions we can all heed and best practices we can each adopt when online – good password hygiene among the most important – we are still at the mercy of the organisations we trust to safeguard our data. Sadly, too many of these have been found wanting, with poor security contributing to the estimated 500,000,000 personal records that were leaked or lost in 2015 alone (source: Symantec).
In the Metro feature I look at passwords and password managers, the rise of ransomware, and how to check if your data has already been leaked. We also see how Facebook boss Mark Zuckerberg may take care to keep his details safe now, but how his previous poor security choices recently came back to bite him.
Read the full feature in the Metro e-edition here.
As a side note, the feature coincides with season two of Golden Globe-winning cybercrime drama Mr Robot airing on Amazon Prime Video. I enjoyed the first series – it’s a good drama with plenty of technical authenticity – and can’t wait now to get stuck into the second.
Watchdog Wednesdays continues on BBC Three and in this week’s film I investigate how easily a criminal can hack a public Wi-Fi hotspot and compromise its users’ personal information.
Coffee shops, high streets and hotels increasingly offer free public Wi-Fi so visitors can sync up while they eat, shop or stay. However, as I’ve reported on before, Wi-Fi hotspots are easy to spoof, are frequently unsecured, and even when there is a password there is still no guarantee of safety.
Hacking the Hotspot
So, in a controlled experiment at a central London coffee shop, I set out to see what the hackers see. What I saw when the Watchdog cameras began rolling surprised even me:
— BBC Three (@bbcthree) April 20, 2016
With very little investment in time or equipment I learnt how to intercept traffic sent between users’ devices laptops, smartphones, tablets and the internet.
Just to be clear – I am not a hacker, I’m a journalist, but picking up the basics was worryingly easy.
The Man in the Middle
My attack (known as a ‘Man in the Middle‘ attack by ARP poisoning) targeted only a single device operated by a member of the BBC crew. It could equally have targeted a number of devices, perhaps all logged in to the Wi-Fi hotspot.
I found unencrypted traffic easily visible, plain text usernames and passwords flashed before my eyes in real time — gold dust for a hacker — and webpage images appeared on my hacktop just as they did on the victim’s machine. I was even able to work around some (but not all) websites’ attempts to enforce HTTPS security.
plain text usernames and passwords flashed before my eyes in real time — gold dust for a hacker
I was shocked that supposedly secure websites such as John Lewis, ebay and Amazon were vulnerable to this basic attack on an iPad, along with email accounts that didn’t have SSL security enabled. Facebook and Twitter didn’t fall for the hack.
Are we really aware of how easy it is for data we send over the airwaves to be intercepted by a silent criminal? I suspect not. This is a perfect crime where victims are unaware that their details have been compromised until the criminal executes his hack hours, days or weeks later when emails get intercepted, accounts get hijacked and funds go missing.
There’s nothing here that’s difficult to get hold of:
- Sony Vaio laptop
- External USB antenna
- Kali Linux operating system
- Tools including Wireshark, sslstrip, ettercap, driftnet
I should add that none of the software used here was illegal; Kali Linux and its bundled utilities are open source, promoted as ‘penetration testing and ethical hacking’ software and is used by security professionals to ensure their corporate networks and public websites remain secure to hackers. Of course, the very same software may also be used by hackers for malicious means. And then, of course, there is YouTube – there’s any number of tutorials here to help you get to grips with the tools and utilities mentioned above.
Stay Safe on Public Wi-Fi Hotspots
So there’s the scare story. But what can you do stay safe when on public WiFi?
- For light browsing I prefer to bring my own network and tether from my smartphone or Mi-Fi, but my data plan is generous (and yes, expensive) to allow for that; if cellular reception is poor it’s painfully slow or impossible.
- A VPN, or Virtual Private Network, is my next security measure – this creates a secure ‘tunnel’ between my laptop, tablet or smartphone and a server elsewhere on the internet into which a fraudster cannot eavesdrop. These can be free, fairly cheap or you can even build your own.
- If all else fails I make sure that websites I exchange data with support safe browsing, denoted by HTTPS and the green padlock (but beware that tools like ‘sslstrip’ can subvert this). I do not ignore errors from the web browser which talk about invalid certificates, even if I don’t understand exactly what they mean – I can visit those websites later when I’m on a secure connection.
How secure are apps? How do you know whether they’re secure if there’s no green padlock or HTTPS visible in an address bar? In my testing I found some apps that are blatantly not secure broadcasting personal details, but I’ll be exploring this in more detail very soon.
Watchdog Wednesdays, a spin-off from the popular BBC1 investigative consumer affairs show, has launched on BBC Three and I’m excited to be fronting its films about online hacks and scams.
My first film, a re-version of an item which aired in Watchdog in October, sees me and LBC’s James O’Brien shed light on a scam known to many as the ‘Microsoft Support Scam’, eventually catching the crooks red-handed.
A three-minute short can only tell so much of the story, so for the many who’ve gotten in touch here’s the technical bit:
On an Apple MacBook running virtual machine software I performed a fresh install of Microsoft Windows 7, loaded anti-malware software, and seeded files in my Users folder and desktop to make it look like a well-used PC. On the host Mac I ran screen recording software, an X server and the Wireshark packet sniffing software to help identify where the scammers were connecting from (alas, we didn’t get to cover the last bit in the film). My final tool was a web browser with some simple who.is tools, and an hour or so raking through some ‘who called me’ forums to find some leads.
The leak of personal details from the Ashley Madison extramarital dating website is one of the significant breaches of sensitive information in the web’s history.
High-profile data leaks have outed private customer data from internet service providers, online retailers and high-tech toy manufacturers in the last few months alone. As a result, cyberattacks have been elevated from trade-press niche news to stop-the-press nine o’clock news.
Yet the Ashley Madison data-breach is different: it wasn’t just email addresses and credit card details that were liberated this time, it was data of the most personal nature. Changing your passwords after a cyberhack is a hassle; salvaging your family relationships after being publicly outed on an adulterous dating website is something infinitely more profound.
While the story was still developing in August 2015 the team from Mentorn Media got in touch to ask if I could add some context to the story for a quick-turnaround documentary they were making for Discovery Networks. Beyond the hack itself, the show sought to explore the wider impact that internet and connected technology is having on 21st century sex and relationships – it’s not often I get to talk about teledildonics and virtual reality sex on television…
The documentary aired in September 2015 in the UK and in January 2016 in Australia. Here’s a trailer:
In whichever direction your moral compass points, Ashley Madison has for a long time been a hugely popular online destination. The Ashley Madison Agency Limited launched in 2001 and, until the events of July and August 2015, welcomed almost 125 million visitors every month from over 50 countries around the world.
