Fraud and scams driven by generative AI are now among the biggest cyber threats in the financial sector
SINGAPORE: Fraud and scams driven by generative artificial intelligence (AI) are among the biggest cyber threats facing today's financial sector. While Singapore businesses saw the lowest number of ransomware attacks in Southeast Asia last year, the city-state became the main source of cyberattacks in the region, with 21.9 million attacks coming from compromised servers in the country in 2024.
According to the not-for-profit organisation FS-ISAC's latest Navigating Cyber 2025 report, released on Tuesday (May 20), these cyber threats create more chances for attackers to exploit geopolitical and economic conflicts, along with the growing sophistication of long-established attacks like distributed denial of service (DDoS) and ransomware.
Steve Silberstein, CEO of FS-ISAC, said, 'The global financial sector's interconnectedness with the supply chain and its ongoing incorporation of emerging technologies add to the challenges. Cross-border collaboration and proactive intelligence sharing are essential to safeguarding the global financial system.'
To stay ahead of nimble cybercriminals, financial firms are expected to: Increase investment in fraud prevention
The report noted that financial institutions should heighten their focus on fraud and scam prevention and detection, as cybercriminals are using real-time payments and cryptocurrencies, making it almost impossible to recover stolen money.
Firms are also expected to adopt 'smart friction' strategies to slow payment authorisations and increase security measures. In addition, sharing fraud intelligence among fraud and cyber teams will be essential to effectively combat fraud. Leverage AI in cyber defence while keeping up the basics
With cybercriminals using generative AI for impersonation scams like deepfakes targeting C-suite executives and fake IT workers, firms are expected to prioritise foundational cyber hygiene practices and robust employee training. Strengthen focus on third-party risk management
In 2024, major third-party breaches shook the sector, with Telegram scams jumping 137.5% and over 100 public officials in Singapore falling victim to AI-powered malicious campaigns.
As many financial institutions rely on the same service providers, a single breach could have a wider impact, the report said.
To minimise the chances of system access in the event of third-party attacks, firms are expected to prioritise application programming interface (API) security and be more proactive in monitoring their supplier security in line with new resilience regulations. Shorten timelines for post-quantum readiness
Recent advancements in quantum computing mean financial firms must start moving their most vulnerable assets to crypto-agile encryption algorithms that can quickly adapt to the quantum era.
Teresa Walsh, FS-ISAC's Chief Intelligence Officer and Managing Director for EMEA, said, 'To ensure operational resilience, firms must adopt a forward-looking cyber posture that incorporates proactive threat modelling, agile defence capabilities, and cross-border collaboration.' /TISG

Gerald Giam draws attention to a petition calling for free-flow tap water at dine-in eateries
SINGAPORE: Workers' Party (WP) Member of Parliament (MP) Gerald Giam (Aljunied Group Representation Constituency [GRC]) pointed out in a Facebook post on Thursday (Jun 12) that there are food and beverage establishments in Singapore where water costs as much as sugary drinks do. He added that this could lead diners in the direction of less healthy options, which in turn could increase the risk of people suffering from diabetes and obesity. A few months ago, Mr Giam called on the Ministry of Sustainability and the Environment (MSE) to encourage eateries, even those in coffee shops and malls, to offer low-cost drinking water as a best practice. He also highlighted a petition recently shared on the platform, calling for free-flowing tap water in dine-in eateries, which a member of the public had launched. 'In a country where tap water is clean, safe, and abundantly available, it is unjustified to restrict access to tap water, especially in establishments that already impose a 10% service charge. We urge the Singapore Government to mandate that dine-in F&B establishments provide free-flow tap water to all customers at no additional cost,' the petition by Yucai Yee reads. It points out the advantages of such a move from public health, environmental, and economic perspectives. Mr Giam, who was re-elected to Parliament for a second term, added that he recognises that from a business standpoint, there is a cost for eateries to offer tap water. He added, however, that this can be recovered when water is offered at cost, and underlined that it should be cheaper than sugary drinks, which would support healthier choices and sustainability goals. In his March speech, Mr Giam said that a culture of taking a reusable water bottle everywhere should be encouraged as part of the city-state's sustainability initiatives. This would reduce Singaporeans' reliance on single-use bottles. This point was also made by the author of the petition, who noted that Singapore ranks number one in the world in terms of per capita bottled water consumption, at 1,129 litres per person per year. According to the petition, 'Reducing bottled water sales by offering tap water can significantly lower single-use plastic waste and environmental harm.' In March 2023, similarly, former WP MP Leon Perera also noted that Singapore is the world's largest user of bottled water. He called on Parliament to distribute more water coolers and dispensers around the island to reduce bottled water use and encourage people to hydrate. /TISG Read also: Leon Perera: Since Singapore is the biggest user of bottled water in the world, why can't we have more water coolers & water dispensers?

Taiwan imposes technology export controls on Huawei, SMIC
Taiwan has blacklisted Huawei Technologies and Semiconductor Manufacturing International Corp (SMIC), dealing another major blow to the two companies spearheading China's efforts to develop cutting-edge AI chip technologies. Taiwan's International Trade Administration has included Huawei, SMIC and several of their subsidiaries in an update of its so-called strategic high-tech commodities entity list, according to the latest version that was made available on its website on Saturday (Jun 14). It didn't publicly announce the change. According to Taiwan's existing regulations, local companies will require approval from the island's government before they can ship anything to users on the entity list. In 2023, Bloomberg News reported that several Taiwanese companies were helping Huawei build infrastructure for an under-the-radar network of chip plants across southern China. The new restrictions imposed by Taipei are likely to at least partially cut off Huawei and SMIC's access to Taiwan's plant construction technologies, materials and equipment essential to build AI semiconductors, such as those made by Taiwan Semiconductor Manufacturing Co (TSMC) for the likes of Nvidia Corp. In Huawei's case, several of its overseas units including in Japan, Russia and Germany were also captured in the update to Taiwan's entity list. Both Huawei and SMIC – and some of their subsidiaries – are also on the US entity list, which has significantly limited the companies' ability to acquire foreign technology.

Sign Up Sign Up Huawei and SMIC didn't immediately respond to requests for comment outside of regular office hours. While Taiwan has for years imposed certain blanket bans on the shipments of critical chipmaking equipment including lithography machines to China, it hasn't included leading Chinese tech companies or chipmakers on its entity list previously. TSMC, the go-to chipmaker for Apple and Nvidia, cut off its supplies to Huawei in 2020 because of US export controls. Huawei, together with SMIC, shocked American politicians in 2023 by releasing an advanced, made-in-China 7-nanometre chip. While the two are struggling to improve their technologies due to various curbs, they are still China's best hope to help fill in the AI chip gap left by a lack of Nvidia's most sophisticated semiconductors. Tensions between Taiwan and China also stepped up a notch earlier this year after Taiwan President Lai Ching-te labelled China a 'foreign hostile force' for the first time and unveiled wide-ranging measures to counter infiltration efforts. China claims the self-governing democracy as its territory and has vowed to unify with Taiwan, using force if necessary. BLOOMBERG

BT boss Kirkby expects AI to deepen job cuts, FT reports
(Corrects typographical error in headline) BT Group Chief Executive Allison Kirkby said advances in artificial intelligence could deepen significant job cuts under way at the British telecoms company, the Financial Times reported on Sunday. Kirkby told the newspaper that BT's plans to cull more than 40,000 jobs and strip out 3 billion pounds ($4 billion) of costs by the end of the decade "did not reflect the full potential of AI". "Depending on what we learn from AI . . . there may be an opportunity for BT to be even smaller by the end of the decade," the FT quoted her as saying. Britain's biggest broadband and mobile provider had said in 2023 that it would cut as many as 55,000 jobs, including contractors, by 2030. Its CEO at the time, Philip Jansen, said the company would rely on a much smaller workforce and significantly reduced cost base by the end of the 2020s. Kirkby, who took over from Jansen a year ago, has also opened the door to a possible future spin-off of Openreach, the company's network infrastructure business, the FT said. She said she did not feel the value of Openreach was reflected in the company's share price and if that persisted, BT "would absolutely have to look at options". In an emailed response to Reuters, BT said that Openreach is not something the company is actively looking at right now. It did not provide further comment on Kirkby's FT interview. BT said last month that strong demand for fibre broadband and more than 900 million pounds of cost savings had helped to shore up its full-year earnings and boost cash flow. Resilience at Openreach offset declines in revenue and profit at its business and consumer units, where legacy voice services continued to wane and handset sales fell. ($1 = 0.7372 pounds)
