Visa using AI to combat AI-driven fraud in New Zeland
0
Launching its latest Security Roadmap for New Zealand, the bold three-year strategy aims to protect consumers and businesses from rapidly evolving cyber threats.
Scams and payment fraud in New Zealand are accelerating rapidly in both scale and sophistication, with AI-powered scams and digital fraud rising sharply across the country. In 2024 alone, scam and card fraud losses reached NZ$194 million[1], with small and medium sized businesses (SMBs) increasingly in the firing line. Unauthorised card fraud surged by 32% over the past 12 months[2], and online shopping scams have overtaken identity theft as the most reported scam type[3]. Despite this, 68% of New Zealanders chose not to report scam incidents[4], citing uncertainty around reporting channels.
'Visa used AI to stop more than NZ$273 million in fraud affecting New Zealanders in 2023 alone. And yet, as AI-enabled fraudsters evolve, we must move faster,' said Anthony Watson, Visa Country Manager for New Zealand and the Pacific Islands. 'That requires relentless innovation and continued investment in next-gen security tools and partnering across the ecosystem to stay ahead of criminals.'
The increasing use of artificial intelligence by criminals is helping them mimic legitimate consumer behaviour, bypass traditional security checks such as SMS passcodes, and manipulate human psychology with alarming precision. Social engineering tactics such as phishing, ransomware, billing scams and card-not-present fraud are now commonplace, with SMBs particularly vulnerable.
To combat this growing threat, Visa's Security Roadmap establishes the key areas for the investment of banks and financial institutions over the coming three years to: prevent enumeration attacks; modernise authentication; adopt a data-driven, risk-based approach to managing risks; strengthen resilience against AI-driven scams; enhance cybersecurity across the ecosystem; and secure digital payments with advanced protocols.
Supporting New Zealand SMBs with fraud prevention tips
To help SMBs protect themselves and their customers, Visa has also launched the SMB Fraud Prevention Toolkit - a suite of practical tips and resources to support small business owners. The toolkit provides step-by-step guidance on identifying, preventing, and responding to threats such as phishing, ransomware, billing scams, card-not-present fraud, and enumeration attacks.
With a 95% increase in scam reports in 2023 and NZ$1.9 million lost to scams targeting businesses[5], the toolkit offers clear checklists, real-world case studies, employee training tips, and incident response plans. 'SMBs are the engine of New Zealand's economy and, increasingly, cyber criminals exploit the most vulnerable point in the payments' ecosystem: humans,' said Watson. 'This toolkit gives business owners in New Zealand, commonly a target for cybercrime, the knowledge and confidence to take control of their security.'
The toolkit also promotes best practices including multi-factor authentication, employee awareness training, secure online transaction protocols, and real-time payment monitoring. It is designed to suit businesses of varying sizes and industries, and encourages a proactive approach to cybersecurity.
Funding innovation through sustainable infrastructure investment
Visa's Roadmap also highlights the importance of sustainable funding mechanisms, such as interchange, to maintain and improve fraud prevention capabilities. These mechanisms support the essential infrastructure behind secure payments, including AI systems, biometric authentication, 24/7 fraud monitoring, and tokenisation.
'Fraud prevention doesn't just happen - it's powered by sustained investment in technology,' said Watson. 'If we want to stay ahead of scammers, we need to ensure the ecosystem remains commercially viable for innovation to thrive. In markets where interchange fees have been significantly reduced, we've observed increased friction and higher fraud rates, leading to poorer customer experiences.'
Visa continues to work closely with banks, acquirers, merchants, and government agencies to implement its security roadmap across the country and ensure New Zealanders are protected in an increasingly digital economy.

Silicon Valley's AI-fuelled madness has echoes of the dotcom crash
I returned to work last week after a brief sabbatical and Silicon Valley, in my absence, has gone and truly lost its mind. Tales of $100 million — even $200 million — pay packages for software developers ricochet through the Valley as AI-induced mania scales new heights. The value of chip giant Nvidia has just crossed the $4 trillion threshold, a 12-fold increase in just 30 months that has turned an estimated 80 per cent of its workforce into millionaires. And then, of course, there are the start-ups. Thinking Machines Lab, a company started by OpenAI co-founder Mira Murati a mere five months ago, has raised $2 billion in funding at a valuation of $10 billion (£7.5 billion). This company has neither product nor revenue. What it does have is a collection of big brains who once worked at OpenAI. And that, apparently, is enough. • OpenAI's former tech boss Mira Murati launches own start-up Ilya Stuskever, another OpenAI refugee, also reeled in $2 billion for his company, Safe Superintelligence — but at a, checks notes, $32 billion valuation! It has yet to trouble the world with a product. History does not repeat itself, as the trope goes, but it rhymes. Which is why the madness to which I have returned takes me back to December 1999. I had just graduated with a liberal arts degree and a surfeit of energetic naivety. The internet boom was in full bloom and so I hatched a cunning, three-stage scheme: move to San Francisco, get a job at a dotcom (any dotcom would do), and then watch my share options explode in value, turning me into a millionaire by the age of 25. You'll be surprised to learn that my watertight plan sprung a few leaks. I did move to San Francisco, and I did land a job at a buzzy dotcom that was so desperate for warm bodies, it looked past the rather underwhelming skills implied by my degree in international relations and Spanish. I lasted four months. The dotcom bubble burst, my employer quickly realised it had no chance of ever raising money again, and deemed me — and much of the company — surplus to requirements. It went under not long after, amid thousands of others. The experience was, in retrospect, a fabulous internship for the business reporter I would become. Seasoned business leaders, top bankers, the world's savviest investors … they had all drunk the Kool-Aid. Otherwise intelligent and canny operators had been swept up in a type of group hysteria, fuelled by a powerful cocktail of optimism, magical thinking and greed. Who needs profits when we are about to change the world? Sound familiar? So is this time 'different', as anyone with a PowerPoint deck and an AI idea to sell would have you believe? I think two things are true. AI will, indeed, change just about every industry and how we live life, in ways large and small. Yet it is also true that we are caught in the midst of a gigantic bubble that, when it pops, will lead to the disappearance of most AI companies and wipe out trillions of dollars of wealth in private and public markets. The latter, after all, is not a big leap. Since the start of 2023 through last month, the 'Magnificent 7' tech stocks — Apple, Microsoft, Alphabet, Meta, Nvidia, Amazon and Tesla — have gained $9.7 trillion in market value. This bears repeating: that figure is the combined value increase, not the overall sum. Put another way, the rise in value of those seven companies over these past two and a half years is equivalent to recreating the entire listed universe of 2,000 companies on the London Stock Exchange — twice. Downstream of those astronomical figures is the bubbling cauldron of Silicon Valley start-ups, which are taking advantage of the mania to raise eye-watering amounts of money at valuations that most have no hope of earning their way into. Indeed, last year alone, Californian start-ups raised nearly $50 billion across more than 850 financing deals, according to data from PitchBook. The upshot is that money is sloshing around to a degree not seen since the internet turned the world upside down. And amid the madness, the biggest beneficiaries are, without question, software nerds. What a time to be a coder! The top keyboard jockeys are being courted with pay packages to rival Premier League footballers. OpenAI's Sam Altman made headlines recently when he said Meta's Mark Zuckerberg was offering $100 million bonuses to lure away his top talent. Andrew Bosworth, Meta's chief technology officer, poured cold water on the claim — sort of. 'Sam is just being dishonest here,' he reportedly told an internal meeting. 'He's suggesting that we're doing this for every single person … Look, you guys, the market's hot. It's not that hot.' So, not every single person, but some? Indeed, just look at what Meta has done in the past month. It paid $14.3 billion for 49 per cent of Scale AI, effectively 'acqu-hiring' the engineers at a start-up that labels training data for AI model developers. Under the deal, 28-year-old founder Alexandr Wang joined Meta's 'SuperIntelligence Labs'. Zuck's bags of cash have lured a handful of senior OpenAI coders to the new unit. He also poached Daniel Gross, the 34-year-old chief executive of SSI, Sutskever's start-up, as well as Nat Friedman, the 47-year-old former chief of Github. Gross and Friedman ran an investment fund together, and it is understood that Meta bought out their stake for about $1 billion to bring them into the fold. Just days after Bosworth's luke-warm denial, reports emerged of an even richer deal. Ruoming Pang, Apple's former head of AI models, was said to have joined after Zuckerberg offered him a multi-year deal worth $200 million. One can understand why so many engineers are happily taking Zuck's money. The Silicon Valley machine is, by design, messy and unpredictable. OpenAI, for example, has jumped from a $1 billion valuation in 2019 to $300 billion today. Anthropic, maker of the Claude chatbot, was founded just four years ago and has already seen its valuation soar to $60 billion. Sales, meanwhile, are on track to top $4 billion over the 12 months — from a standing start in 2022. OpenAI has forecast $13 billion in revenue for 2025, all from a suite of products that did not exist three years ago. The mind boggles. And yet, soaring growth today does not guarantee success tomorrow. Remember when Yahoo was the master of all it surveyed? Remember when MySpace dominated social media? For every ten companies that get venture capital backing, roughly five will die, four will limp on, merge or get bought for a modest sum, and one, if its investors are lucky, will turn into a properly successful company. Perhaps it becomes a unicorn – until it is disrupted by the next white-hit startup. The sands are always shifting, so when offered life-changing, generational wealth, many are taking it. And yes, Zuck has spent $15bn-plus in a matter of weeks for a battalion of sun-starved coders, but old hands see his moves as utterly logical. Because if indeed AI is the generational technology that Silicon Valley believes it is, those who grab control of it stand to make hundreds of billions, even trillions, as it replaces humans and takes over more and more of the economically valuable work. Reid Hoffman, the billionaire LinkedIn founder and early Meta investor, said last week: 'The talent race, to your average American, looks crazy — the amount of money you're paying individuals in order to do this.' But he added: 'If you invent the thing that essentially — for example, my own start-up, Manas AI, is trying to cure cancer — transforms industries, and if you think this individual is the one to do it, then it begins to get more economically rational.' • Don't fear AI: used well, it can empower us all There is, of course, another option — that AI sets off a more gradual and messy transformation, much like the internet just before the dotcom blowout, when most companies crashed and burned but a few generational start-ups emerged from the chaos. That appears to be the view of Peter Thiel, another billionaire techie. 'My place holder is that it's roughly on the scale of the internet in the late '90s,' he said recently. 'It might be enough to create some great companies. And the internet added maybe a few percentage points to gross domestic product, maybe 1 per cent to GDP growth every year for 10, 15 years. It added some to productivity. That's roughly my place holder for AI.' So, no revenue. No product. No problem. Until, of course, it is.

James McMurdock took bank salary while ‘claiming Covid loans'
A former Reform MP who allegedly borrowed tens of thousands of pounds in Covid loans received a salary from an international bank throughout the pandemic. James McMurdock suspended himself from Reform UK last week after The Sunday Times posed questions about £70,000 he borrowed through two firms in 2020: one previously dormant, the other with negligible assets. The South Basildon & East Thurrock MP later said he had quit Nigel Farage's party after taking 'specialist advice' which 'is privileged and which I choose to keep private at this time'. He remains under investigation by the parliamentary commissioner for standards and was separately referred to the Public Sector Fraud Authority by the Covid corruption commissioner last week. Reform has called for him to resign so a by-election can take place.

No limit to ChatGPT searches ‘remarkable' given environmental impact
Astronaut Tim Peake says it is 'remarkable' that there is no limit on ChatGPT searches, and that space holds 'many answers' to the climate crisis, at Goodwood Festival of Speed. Shielded from the midday blazing heat and the roar of motor cars in a darkened tent, Future Lab displayed technologies, robotics and virtual realities to excite the imaginations of festival goers in Chichester on Saturday. Among the displays was a humanoid robot, with moving, re-active facial features powered by ChatGPT responses, creators call it Ameca. Major Peake, the first British man to visit the International Space Station, has worked with Future Lab since its first iteration in 2017. Despite his excitement about the new technologies and possible uses of artificial intelligence (AI), he acknowledged the environmental impact of data centres used to run them. He told the PA news agency: 'There is no limit to how much they can use ChatGPT, they can be streaming cat videos and making avatars and doing what they want with no – no concern of how much energy that is using and how much water is using to cool. 'It's limitless, and it shouldn't be. Every single google search is having an impact, and an AI google search is a 30% increase in energy to function than a standard Google search and you don't even get the choice now.' Tech companies have hugely increased their water consumption needs for cooling data centres in recent years, according to The Times, writing one 100 word email using the (GP-4) version of the chatbot is equivalent to a 500ml water bottle. 'Maybe that's what we need next to the google search box – 'please search responsibly',' the former astronaut added. Business Energy UK has estimated that ChatGPT may presently use around 39.98 Million kWh per day — enough to charge eight million phones. Major Peake was quick to argue that the answers lie in space, using 'orbital data centres', he added that he was working with a company, Axium Space, who were set to launch two nodes later this year. He explained: 'The idea being that by the mid-2030s you have cost-parity between choosing an Orbital data centre vs a cloud server – you know, a database that would be here on earth. 'Because in space you've got clean, free limitless energy and you've got limitless ability to have thermal rejection into the vacuum of space with no impact on the environment.' Critics of this approach, such as Dr Domenico Vicinanza – associate professor of intelligent systems and data science at Anglia Ruskin University in the UK, say it may not be that simple. 'Space-based data centres would require not only the data equipment but also the infrastructure to protect, power, and cool them. All of which add up in weight and complexity,' Dr Vicinanza told the BBC. Asked about space and the environment, Major Peake said: 'It might not hold all the answers but it holds many answers and it forms a large percentage of the solution I think. 'In terms of right now, more than 50% of our climate data is coming from space so it's the finger on the pulse of the planet.' The displays at Future Lab presented a window into the cutting edge of science, mapping deep space, exploring the depths of the ocean, and the latest AI and robotics. The CEO of the National Robotarium, Stuart Miller, said the event 'helped people understand what's coming' and added that they wanted to ask how robots and humans can 'live in harmony together'. Ameca, the humanoid robot created by Cornwall-based company Engineered Arts, was the star attraction for many – able to hold and double back to parts of a conversation and answer questions quickly. Major Peake said: 'Her non-verbal responses really surprised me, and then you realise that's AI's interpretation of human interaction as well so it's not just the verbal responses you're getting, you're getting the AI response in terms of non-verbal skills.' Surrounded by cars, in a corner of a field in Chichester, some of the UK's newest scientific innovations piqued the interest of the crowds, but Major Peake acknowledged there has to be 'a balance' in how much AI should do, and considered whether it erodes human curiosity. 'There is absolutely a balance and that's why it's important to educate people that AI's just a tool – a tool for humans to use.' he said. Later asking: 'Does ChatGPT, does AI just make it too easy for us? Does it just give it to us rather than making us work for it? And how much pleasure is there in actually finding something out rather than just reading and learning something?'
