Think like criminals, anticipate cyber attack tactics: Experts
Sign up now: Get ST's newsletters delivered to your inbox SINGAPORE - Organisations need to think like cyber criminals and proactively run simulated real-world attacks internally to better prepare their cyber defenders in the age of artificial intelligence (AI), speakers at a cybersecurity conference said. 'Globally, we are seeing growing interest, and increasingly brazen activity, against critical infrastructure: ports, utilities, telecommunications, transport networks,' said Singapore's Defence Cyber Chief on July 4. 'Not perhaps for immediate disruption or commercial gain, but to map dependencies, identify vulnerabilities and pre-position for possible future leverage,' Colonel (COL) Clarence Cai. 'Now add AI to the mix — and this threat landscape goes on steroids.' Urging organisations to use AI to anticipate attack tactics, he said: 'This mindset shift might be the most important variable in the fight to come.' COL Cai was one of several speakers at ST Engineering's Cybersecurity Summit 2025, which brought together industry leaders to discuss AI-powered cyber attacks, and plans to stay ahead in an increasingly complex threat landscape. Cyber attackers can run countless permutations on how to breach systems, considering factors such as credentials to unlock systems and potential points of exploitation, he said. In sharp contrast, defenders often think in a more checklist-oriented manner, he said during his keynote address at the event. He added that this fundamental difference gives attackers the upper hand - unless defenders learn to adopt the dynamism that attackers have, which would level the playing field. He said that the mindset shift has already taken place in the military, citing what is being done at Singapore's Cyber Defence Test and Evaluation Centre (CyTEC). CyTEC was established in 2015, and falls under the banner of the Defence Cyber Command (DCCOM). It provides a virtual sandbox environment that simulates cyber threat scenarios to test defenders' skills and responses. 'CyTEC is where our most promising cyber minds—including national servicemen—develop AI-native workflows for red teaming and defence,' he said. Red teaming is when ethical hackers simulate cyber attacks so organisations can test the effectiveness of their cybersecurity system. In his speech, COL Cai said defence is no longer just about where uniformed personnel meet, but also about where vulnerabilities exist. People and commercial organisations face non-kinetic, military-grade threats, said COL Cai, citing the cyber attack on Marks & Spencers earlier in the year which resulted in an estimated £300 million (S$522 million) loss in profit. 'The T-72 (battle tank) never rolled in - but the digital equivalent of a precision strike did,' he added. Military conflicts also no longer just target weapon platforms, but also the digital infrastructure that people rely on, said COL Cai. He said: 'During recent hostilities between Israel and Iran, the world watched hypersonic missiles light up the night sky. But in the shadows, cyber attacks disrupted air traffic, spoofed the global positioning system, and interfered with hospital and financial services. 'These attacks weren't just at the front line, they were levelled at the foundations of modern society.' Urging all organisations, including small and medium-sized enterprises (SMEs) to prepare early and systematically, the chief executive of Cyber Security Agency (CSA) of Singapore David Koh likened cybersecurity to brakes on a car. 'If you want to go fast, you need good brakes. If you want to digitalise, you need good cybersecurity,' said Mr Koh. He added that digital resilience is a basic requirement for everybody, to succeed in an increasingly digital economy. 'When the security posture of SMEs is strengthened, then there is a multiplicative effect. The protection extends beyond the SMEs themselves into the wider supply chain ecosystem, which all of us depend on.' During the summit, Senior Minister of State for Digital Development and Information Tan Kiat How said Singapore has built a strong cybersecurity foundation. He cited initiatives such as the Infocomm Media Development Authority's CTO-as-a-Service, which gives SMEs access to expert digital guidance, and CSA's CISO-as-a-Service, which helps SMEs overcome resource constraints and knowledge barriers they may face in implementing cybersecurity. However, he added that consistently building on this foundation is important to keep up with the evolving threat landscape. Eight in 10 Singapore organisations had experienced a cybersecurity incident in 2023, said Mr Tan, citing CSA's Singapore Cybersecurity Health Report 2023. Of these, 99 per cent reported suffering business impacts, with the top three being business disruption, data loss, and reputational damage. 'Some SMEs hold the view that they are too small or too unimportant to be targeted,' said Mr Tan, adding that he hears this feedback sometimes from SMEs. 'I often explain that threat actors may target small companies as a way to reach bigger targets,' he added. 'And when one firm is compromised, the impact may cascade through the broader industry sector - potentially disrupting services, leaking data, and even compromising national infrastructure,' he said, urging firms to up their game. 'Let us not be remembered for what we failed to protect, but for what we had the foresight to be prepare for.'

Fast Lane: Cupra's three models, customised Bentley SUV, OneMotoring stops accepting PayPal
Sign up now: Get ST's newsletters delivered to your inbox Incoming: Cupra Formentor (left) and Terramar (right) are among the new models to be introduced in Singapore on July 31. Petrol-powered Cupra ready Spanish car brand Cupra will be launching three petrol-powered models in Singapore: the Leon hatchback and two sport utility vehicles (SUVs) – the Formentor and Terramar – on July 31. These are the first non-electric models to be introduced since Volkswagen Group Singapore announced that it was taking over the distributorship of the brand here in 2023. The Leon is the most familiar nameplate among the three, having been available here before Cupra was spun off as an independent brand from Volkswagen-owned Spanish brand Seat in 2018. The latest model is powered by a 1.5-litre mild-hybrid engine. At 4,451mm long, the facelifted Cupra Formentor VZ is broadly a rival to the BMW X2. It has a 2-litre turbocharged engine rated at 328hp and 440Nm of torque, giving the SUV a 0-100kmh timing of 4.8 seconds. The Formentor is the first model to be developed as a Cupra-only model without a Seat-branded equivalent. It was offered in pre-facelift form between 2021 and 2023 by the brand's previous representative in Singapore. The updated version features the brand's more aggressive design, similar to the flamboyant Tavascan electric vehicle. The Terramar is slightly lower and longer overall than the Volkswagen Tiguan. The version to be offered in Singapore is powered by a 1.5-litre turbocharged engine with mild-hybrid technology. New car owners frustrated by large touchscreens: Survey Love and hate: Owners are attracted by the large screens in their new cars, but dread having to go through multiple steps to access basic controls. ST PHOTOS: CHONG JUN LIANG Enormous touchscreen infotainment systems are the leading source of complaints among US car owners in the first 90 days of ownership.

'By retaining dedicated physical controls for some of these interactions, automakers can alleviate pain points and simplify the overall customer experience,' he added. Premium vehicles were also found to have more quality issues than mass-market models, especially with the exterior. Among the variety of propulsion solutions, plug-in hybrids were more problematic than pure electric vehicles. The study also found that carmakers are struggling to provide cupholders that are able to accommodate the increasing variety of shapes and sizes of reusable containers that consumers are using. Into its 39th year, the latest study is based on responses from 92,694 car buyers and those who are leasing new model year 2025 cars. Besides surveying them after 90 days of ownership, it also factors in repair visit data based on real-world events reported to new car dealers. Black and pink customised Bentley took 132 hours to build Pretty in pink: The specially customised Bentley SUV took 132 hours to build. PHOTO: BENTLEY MOTORS Bentley has unveiled a customised candy pink-coloured Bentayga EWB Azure, complete with painted 22-inch wheels and an interior that is a mix of black and pink. The car was commissioned by a customer of Bentley Palmyra, a dealer in New Jersey, United States. The special SUV took 132 hours to build, of which 24 hours were spent on the exterior paint and 18 hours went towards producing the trim panels and wood set for the cabin. Being the extended wheelbase version of the SUV, the car features the Bentley Airline Seat option, which has 22-way adjustment, an auto climate sensing system and a massage function. Between the rear seats is an integrated cooler that can carry a 750ml bottle, along with two handcrafted Cumbria Crystal flutes, housed behind a frosted glass door. No more PayPal at OneMotoring from July 6 From July 6, OneMotoring, a website by the Land Transport Authority (LTA), will no longer accept payment by PayPal for its digital services, such as renewing road tax. Instead, payment can be done using credit cards, Google Pay or Apple Pay. From June 30, a limited access code instead of the last four characters of the owner's identification number will be used for some services, such as getting a vehicle's scrap value. In its memo sent to motor dealers, LTA said the move was to enhance the access security for such services. Ex-Ferrari boss joins McLaren Group Road race: New board director Luca di Montezemolo will be involved with the production car side of the McLaren business. PHOTO: MCLAREN AUTOMOTIVE Former Ferrari boss Luca di Montezemolo has joined the board of McLaren in a move that the Italian supercar company may not take too kindly to. Reuters reported that the 77-year-old Italian was registered as a director of Abu Dhabi-owned McLaren Group, which controls McLaren Automotive that is based in Woking, Britain, on June 27. Mr Montezemolo joined Ferrari in 1973 as founder Enzo Ferrari's assistant. He became team manager in 1974, a year before the late Austrian triple Formula One (F1) champion Niki Lauda secured his first title. He also headed the race team when racing ace Michael Schumacher won five of his career wins between 2000 and 2004. He stepped down as Ferrari's chairman in 2014. While British company McLaren is a relative newcomer in making road-going sports cars – the first model, the MP4-12C, was launched in 2010 – its rivalry with Italian team Ferrari in F1 goes back decades. Italian sports newspaper Tuttosport called the latest move 'a slap in the face of Ferrari'. In an interview with Italian news agency Ansa, Mr Montezemolo said his heart 'is and always will be red' and his new role was on the automotive side and did not involve F1.
