Visa's 24/7 war room takes on global cybercriminals
The numbers that the payments giant grapples with are enormous. Every year, US$15 trillion flows through Visa's networks, representing roughly 15 per cent of the world's economy. And bad actors constantly try to syphon off some of that money.
Modern fraudsters vary dramatically in sophistication.
To stay ahead, Visa has invested US$12 billion over the past five years building AI-powered cyber fraud detection capabilities, knowing that criminals are also spending big.
'You have everybody from a single individual threat actor looking to make a quick buck all the way to really corporatized criminal organisations that generate tens or hundreds of millions of dollars annually from fraud and scam activities,' Michael Jabbara, Visa's global head of fraud solutions, told AFP during a tour of the company's security campus.
'These organisations are very structured in how they operate.'

The best-resourced criminal syndicates now focus on scams that directly target consumers, enticing them into purchases or transactions by manipulating their emotions.
'Consumers are continuously vulnerable. They can be exploited, and that's where we've seen a much higher incidence of attacks recently,' Jabbara said.
Scam centers
The warning signs are clear: anything that seems too good to be true online is suspicious, and romance opportunities with strangers from distant countries are especially dangerous.
'What you don't realise is that the person you're chatting with is more likely than not in a place like Myanmar,' Jabbara warned.
He said human-trafficking victims are forced to work in multi-billion-dollar cyber scam centers built by Asian crime networks in Myanmar's lawless border regions.
The most up-to-date fraud techniques are systematic and quietly devastating.
Once criminals obtain your card information, they automatically distribute it across numerous merchant websites that generate small recurring charges - amounts low enough that victims may not notice for months.
Some of these operations increasingly resemble legitimate tech companies, offering services and digital products to fraudsters much like Google or Microsoft cater to businesses.
On the dark web, criminals can purchase comprehensive fraud toolkits.
'You can buy the software. You can buy a tutorial on how to use the software. You can get access to a mule network on the ground or you can get access to a bot network' to carry out denial-of-service attacks that overwhelm servers with traffic, effectively shutting them down.
Just as cloud computing lowered barriers for startups by eliminating the need to build servers, 'the same type of trend has happened in the cyber crime and fraud space,' Jabbara explained.
These off-the-shelf services can also enable bad actors to launch brute force attacks on an industrial scale -- using repeated payment attempts to crack a card's number, expiry date, and security code.
The sophistication extends to corporate-style management, Jabbara said.
Some criminal organizations now employ chief risk officers who determine operational risk appetite.
They might decide that targeting government infrastructure and hospitals generates an excessive amount of attention from law enforcement and is too risky to pursue.
'Millions of attacks'
To combat these unprecedented threats, Jabbara leads a payment scam disruption team focused on understanding criminal methodologies.
From a small room called the Risk Operations Centre in Virginia, employees analyze data streams on multiple screens, searching for patterns that distinguish fraudulent activity from legitimate credit card use.
In the larger Cyber Fusion Centre, staff monitor potential cyberattacks targeting Visa's own infrastructure around the clock.
'We deal with millions of attacks across different parts of our network,' Jabbara noted, emphasizing that most are handled automatically without human intervention.
Visa maintains identical facilities in London and Singapore, ensuring 24-hour global vigilance. AFP

Under attack by Trump's tariffs, Asian countries seek out better friends
US President Donald Trump is erecting new trade barriers and demanding deep concessions from US trading partners by Aug 1. SEOUL, South Korea – For most countries that received US President Donald Trump's letters last week threatening steep tariffs, especially the Asian nations with economies focused on supplying the United States, there are no obvious substitutes as a destination for their goods. But they are doing their best to find them. Business and political leaders around the world have been roundly baffled by the White House's imposition of new duties , even as governments shuttled envoys back and forth to Washington offering new purchases and pledges of reform. Mr Trump is erecting new trade barriers and demanding deep concessions by Aug 1, claiming years of grievance because America buys more than it sells. 'Across the world, tools once used to generate growth are now wielded to pressure, isolate and contain,' Malaysian Prime Minister Anwar Ibrahim said at a gathering of South-east Asian leaders on July 9. 'As we navigate external pressures, we need to fortify our foundations. Trade among ourselves. Invest more in one another.' There are already a few signs of such efforts. South Korea's new president, Lee Jae Myung, sent special envoys to Australia and Germany to discuss defence and trade issues, and plans on dispatching delegations to several others. Brazil and India announced plans to increase their bilateral trade by 70 per cent, to US$20 billion (S$26 billion). Indonesia says it is nearing a treaty with the European Union that would drop most tariffs on both sides to zero. And in Vietnam, which Mr Trump said had accepted 20 per cent tariffs on its goods headed to the United States before last week's letters, the deputy trade minister emphasised efforts to reduce her country's reliance on American consumers by leveraging other trade agreements. 'As more and more countries are feeling that it's more difficult to satisfy US demands, then their interest in working with others is going to intensify,' said Ms Wendy Cutler, vice-president at the Asia Society Policy Institute.

During Mr Trump's first term, China retaliated against US tariffs by buying smaller amounts of US soybeans. Brazil filled the hole and now supplies most of China's soybean demand, leaving American farmers with too much product and not enough buyers. In 2017, China boycotted goods from South Korea in retaliation for its willingness to host an American antiballistic missile system, seriously damaging South Korea's China-dependent consumer and tourism industries. In response, South Korea expanded trade and investment with Indonesia, Malaysia and Vietnam. Since Asian nations had already been working to diversify their customer bases, the current drive is not entirely new. But the region is still far from seamlessly integrated. South Korea, for example, has resisted joining the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, a trade pact that rose from the ashes of negotiations with the United States that foundered in 2016. Mr Byung-il Choi, a South Korean economist and former trade negotiator, has been urging his country to join that agreement, which its neighbour Japan has signed. New hostility from Washington may finally make it possible, and South Korea's president, Mr Lee, has been more amenable to Japan than many expected during his campaign. 'Japan and Korea believed that we are a staunch, ironclad ally of the US, but Donald Trump doesn't believe in allies,' Mr Choi said. 'So Japan is anxious to get more significant members, and Korea's incoming government is saying, 'In the name of national interest, we could do anything.'' The latest tariff barrage has arrived as China has also been flooding the world with cheap goods to sustain its export-based growth. That oversupply of cars, appliances, electronics and textiles makes it harder for China's neighbours to find their own niches. Some of them could benefit from the Trump administration's determination to prevent Chinese goods from filtering through other countries to American ports. Chinese businesses have already been setting up factories in South-east Asia in search of lower labour costs, and the new agreements may encourage them to locate more of their supply chain outside China as well. Companies in the region, squeezed by competition from China and now by tariffs, could work to improve their productivity and maintain market share. 'They can do more efficiencies, maybe investing in new technology, digitalising some of their factories, in order to reduce costs,' said Mr Dionisius Narjoko, a senior economist at the Economic Research Institute for Asean and East Asia. 'It could be cheaper to export, and therefore they can become more competitive in new markets or even in the US.' To increase their citizens' incomes, developing nations in South-east Asia still need to create more homegrown enterprises. It's not enough to remain the workshop for major powers. That requires steady leadership and focused investment, of the sort that allowed South Korea and Japan to grow into manufacturing powerhouses. For example, while mostly Japanese companies now produce more than 1 million cars a year in Thailand, and South Korean giant Samsung makes many of its cellphones in Vietnam, those South-east Asian countries remain relatively poor. 'They need to internalise some industrial technology from the foreign direct investment,' said Dr Kim Dongsoo, a senior research fellow with the Korea Institute for Industrial Economics and Trade. 'Everybody knows that's kind of a problem, but not all governments can escape from that trap.' Ultimately, it could be advantageous for the countries that have become the targets of Mr Trump's tariff campaign to come up with a more collective response. So far, that hasn't happened, as world leaders have continued to try to secure more favourable treatment for their own countries. Even the growing Brics alliance, which drew Mr Trump's ire as it met in Rio de Janeiro and welcomed Indonesia as an official member, stopped short of taking any action to resist US tariffs. 'I haven't seen indications that South-east Asian nations are trying to join together and present a united front,' said Dr Alexander Hynd, an assistant professor at the University of Melbourne's Asia Institute. But that could change if the current pace of upheaval continues. 'The US is fairly rapidly attempting to dismantle the system that it set up, which is surprising a lot of people,' Dr Hynd said.

Indonesia foils attempt to smuggle 1,200 endangered birds
Sign up now: Get ST's newsletters delivered to your inbox KUPANG, Indonesia - Indonesian authorities have foiled a smuggling attempt of more than 1,200 endangered Javan white-eye birds after discovering them stuffed into cages, they said on July 13. The popular cage-bird is listed as endangered by the International Union for the Conservation of Nature and a protected species by the Indonesian environment and forestry ministry. Officials found the huge cache of birds in eight cages on July 11, including 140 that died, at a port on Flores island in eastern Indonesia, Mr Joko Waluyo, an official at a provincial conservation agency, told reporters Sunday. The birds were due to be taken by ferry to Surabaya, a city in the east of Indonesia's main island Java. 'The alleged perpetrator, who has not yet been found, brought Javan white-eye birds in 8 bird cages. The number of birds that were attempted to be transported was 1,260, 140 of which were found dead,' said Mr Joko. The surviving white-eye birds were released back into the wild. 'The release aims to save all secured (birds), increase the population in nature, and raise public awareness,' he said. Under Indonesian law, poaching or trading of protected species is punishable up to 15 years in prison. Indonesia's illegal trade in wildlife along with habitat loss has driven numerous endangered species, from the Sumatran elephant to the orangutan, to the brink of extinction. AFP

SpaceX to invest US$2 billion in Musk's xAI startup
[NEW YORK] SpaceX has committed US$2 billion to xAI as part of a US$5 billion equity round, deepening the ties between tech billionaire Elon Musk's ventures as his artificial intelligence startup races to compete with rival OpenAI, the Wall Street Journal reported on Saturday. The investment follows xAI's merger with X and values the combined company at US$113 billion, with the Grok chatbot now powering Starlink support and eyed for future integration into Tesla's Optimus robots, the report added. In response to a post on X about whether Tesla, could also invest in xAI, Elon Musk said on Sunday (Jul 13), 'It would be great, but subject to board and shareholder approval,' without confirming or denying the Journal report on SpaceX's investment plans in xAI. SpaceX, xAI and Tesla did not immediately respond to requests for comment. Reuters could not immediately confirm the WSJ report. Despite recent controversies involving Grok's responses, Musk has called it 'the smartest AI in the world,' and xAI continues to spend heavily on model training and infrastructure. REUTERS
