OpenAI's Sam Altman warns of AI voice fraud crisis in banking
Altman spoke at a Federal Reserve conference Tuesday in Washington.
'A thing that terrifies me is apparently there are still some financial institutions that will accept the voiceprint as authentication,' Altman said. 'That is a crazy thing to still be doing. AI has fully defeated that.'

Voiceprinting as an identification for wealthy bank clients grew popular more than a decade ago, with customers typically asked to utter a challenge phrase into the phone to access their accounts.

But now AI voice clones, and eventually video clones, can impersonate people in a way that Altman said is increasingly 'indistinguishable from reality' and will require new methods for verification.
'That might be something we can think about partnering on,' said Fed Vice Chair for Supervision Michelle Bowman, the central bank's top financial regulator, who was hosting the discussion with Altman.

Asian markets gain, with Japan's Nikkei up 3.5%, lifted by deal on Trump's tariffs
A person walks in front of an electronic stock board showing Japan's Nikkei index at a securities firm Wednesday, July 23, 2025, in Tokyo. (Kyodo News via AP) TOKYO — Asian shares rallied on Wednesday, with Tokyo's benchmark Nikkei 225 index up 3.5 per cent after Japan and the U.S. announced a deal on U.S. President Donald Trump's tariffs. The agreement as announced calls for a 15 per cent import duty on goods imported from Japan, apart from certain products such as steel and aluminum that are subject to much higher tariffs. That's down from the 25 per cent Trump had said would kick in on Aug. 1 if a deal was not reached. 'This Deal will create Hundreds of Thousands of Jobs — There has never been anything like it,' Trump posted on Truth Social, noting that Japan was also investing 'at my direction' US$550 billion into the U.S. He said Japan would 'open' its economy to American autos and rice. Japan's benchmark Nikkei 225 gained 3.5 per cent in afternoon trading to 41,171.32. Hong Kong's Hang Seng jumped 1.4 per cent to 25,470.25, while the Shanghai Composite index was little changed, gaining less than 0.1 per cent to 3,582.30. Australia's S&P/ASX 200 edged up 0.7 per cent to 8,737.20 and the Kospi in South Korea edged 0.4 per cent higher to 3,183.77. 'President Trump has signed two trade deals this week with the Philippines and Japan which is likely to keep market sentiment propped up despite deals with the likes of the EU and South Korea remaining elusive, for now at least,' Tim Waterer, chief market analyst at Kohle Capital Markets, said in a report. There was a chorus of no comments from the Japanese automakers, despite the latest announcement, including Toyota Motor Corp., Honda Motor Co and Nissan Motor Corp. Japanese companies tend to be cautious about their public reactions, and some business officials have privately remarked in off-record comments that they hesitate to say anything because Trump keeps changing his mind. The Japan Automobile Manufacturers' Association also said it had no comment, noting there was no official statement yet. Japan's Prime Minister Shigeru Ishiba welcomed the agreement as beneficial to both sides. Toyota stock jumped 14 per cent in Tokyo trading, while Honda was up nearly 11 per cent and Nissan added eight per cent. In other sectors, Nippon Steel, which is acquiring U.S. Steel, rose 2.4 per cent while video game maker and significant exporter Nintendo Co. added 0.7 per cent. Sony Group surged 4.6 per cent. Wall Street inched to another record on Tuesday following some mixed profit reports, as General Motors and other big U.S. companies gave updates on how much Trump's tariffs are hurting or helping them. The S&P 500 added 0.1 per cent to the all-time high it had set the day before, closing at 6,309.62. The Dow Jones Industrial Average rose 0.4 per cent to 44,502.44. The Nasdaq composite slipped 0.4 per cent from its own record, to 20,892.68. So far, the U.S. economy seems to be powering through the uncertainty created by Trump's on-and-off tariffs. Many of Trump's proposed taxes on imports are currently on pause, and the next big deadline is Aug. 1. Talks are underway on possible trade deals with other countries that could lower the stiff proposals before they kick in. Trump said he reached a trade agreement with the Philippines following a meeting Tuesday at the White House, that will see the U.S. slightly drop its tariff rate for the Philippines without paying import taxes for what it sells there. In the bond market, Treasury yields sank as traders continue to expect the U.S. Federal Reserve to wait until September at the earliest to resume cutting interest rates. The yield on the 10-year Treasury eased to 4.34 per cent from 4.38 per cent late Monday. In other dealings early Wednesday, U.S. benchmark crude oil gained 15 cents to $65.46 a barrel. Brent crude, the international standard added 16 cents to $68.74 a barrel. In currency trading, the U.S. dollar rose to 146.78 Japanese yen from 146.64 yen. The euro cost $1.1740, down from $1.1754.

Canadian researchers create tool to remove anti-deepfake watermarks from AI content
OpenAI CEO Sam Altman participates in a panel discussion during the annual meeting of the World Economic Forum in Davos, Switzerland, Thursday, Jan. 18, 2024. OpenAI was one of the major tech firms that promised to pursue watermarking technology. (AP Photo/Markus Schreiber) OTTAWA — University of Waterloo researchers have built a tool that can quickly remove watermarks identifying content as artificially generated — and they say it proves that global efforts to combat deepfakes are most likely on the wrong track. Academia and industry have focused on watermarking as the best way to fight deepfakes and 'basically abandoned all other approaches,' said Andre Kassis, a PhD candidate in computer science who led the research. At a White House event in 2023, the leading AI companies — including OpenAI, Meta, Google and Amazon — pledged to implement mechanisms such as watermarking to clearly identify AI-generated content. AI companies' systems embed a watermark, which is a hidden signature or pattern that isn't visible to a person but can be identified by another system, Kassis explained. He said the research shows the use of watermarks is most likely not a viable shield against the hazards posed by AI content. 'It tells us that the danger of deepfakes is something that we don't even have the tools to start tackling at this point,' he said. The tool developed at the University of Waterloo, called UnMarker, follows other academic research on removing watermarks. That includes work at the University of Maryland, a collaboration between researchers at the University of California and Carnegie Mellon, and work at ETH Zürich. Kassis said his research goes further than earlier efforts and is the 'first to expose a systemic vulnerability that undermines the very premise of watermarking as a defence against deepfakes.' In a follow-up email statement, he said that 'what sets UnMarker apart is that it requires no knowledge of the watermarking algorithm, no access to internal parameters, and no interaction with the detector at all.' When tested, the tool worked more than 50 per cent of the time on different AI models, a university press release said. AI systems can be misused to create deepfakes, spread misinformation and perpetrate scams — creating a need for a reliable way to identify content as AI-generated, Kassis said. After AI tools became too advanced for AI detectors to work well, attention turned to watermarking. The idea is that if we cannot 'post facto understand or detect what's real and what's not,' it's possible to inject 'some kind of hidden signature or some kind of hidden pattern' earlier on, when the content is created, Kassis said. The European Union's AI Act requires providers of systems that put out large quantities of synthetic content to implement techniques and methods to make AI-generated or manipulated content identifiable, such as watermarks. In Canada, a voluntary code of conduct launched by the federal government in 2023 requires those behind AI systems to develop and implement 'a reliable and freely available method to detect content generated by the system, with a near-term focus on audio-visual content (e.g., watermarking).' Kassis said UnMarker can remove watermarks without knowing anything about the system that generated it, or anything about the watermark itself. 'We can just apply this tool and within two minutes max, it will output an image that is visually identical to the watermark image' which can then be distributed, he said. 'It kind of is ironic that there's billions that are being poured into this technology and then, just with two buttons that you press, you can just get an image that is watermark-free.' Kassis said that while the major AI players are racing to implement watermarking technology, more effort should be put into finding alternative solutions. Watermarks have 'been declared as the de facto standard for future defence against these systems,' he said. 'I guess it's a call for everyone to take a step back and then try to think about this problem again.' This report by The Canadian Press was first published July 23, 2025.

Turkey and Britain sign preliminary deal for Eurofighter Typhoon jets
ANKARA, Turkey (AP) — Turkey and Britain on Wednesday signed a preliminary agreement for the sale of Eurofighter Typhoon fighter jets to Turkey, a significant step in Ankara's efforts to modernize its air fleet. Turkish Defense Minister Yasar Guler and his British counterpart, John Healey, inked a memorandum of understanding during a defense industry fair in Istanbul, Turkey's Ministry of National Defense said. NATO member Turkey has long aimed to buy 40 Eurofighter jets, which are built by a consortium of British, German and Italian companies. Germany reportedly initially opposed the sale but later reversed its position. Britain led negotiations on behalf of the consortium. A Turkish defense ministry statement said the memorandum takes the two countries 'one step closer to a full agreement on the Typhoon.' 'Both Ministers welcome signature as a positive step towards bringing Turkey into the Typhoon club and share a mutual ambition to conclude the necessary arrangements as soon as possible,' it added. Turkish officials have said that they are still negotiating over pricing and technical terms, saying that they have received an initial offer and expect to submit a counter-proposal. Monday Mornings The latest local business news and a lookahead to the coming week. Turkey is also seeking to return to the U.S.-led F-35 fighter jet program, from which the country was ousted in 2019, following its purchase of Russian-made S-400 missile defense systems. The U.S. said the systems posed a risk to the F-35s. Turkey is also developing a domestic fifth-generation fighter jet, the KAAN, which is slated to be operational in 2028.
