South Korea orders SK Telecom to boost data security after major leak
The directive comes after the country's largest mobile carrier disclosed in April that it had suffered a major data breach caused by a malware attack.
The Ministry of Science and ICT said it will impose a fine of up to 30 million won (US$21,970), and required SK Telecom to strengthen its security protocols. These include conducting security audits at least quarterly, placing data governance under the direct oversight of the CEO, and increasing investment and staffing in data security.
"This incident serves as a wake-up call for information protection not only in the domestic telecommunications industry but also across the entire network infrastructure," said Science Minister Yoo Sang-im in a statement, following a government investigation.
SK Group chairman Chey Tae-won apologised last month for the breach, and SK Telecom said it would take full responsibility for any harm caused. The breach has sparked alarm among its 23 million users over the possible theft of personal and financial data.
In response, the carrier said it would provide free Universal Subscriber Identity Module (USIM) replacements to all affected users at more than 2,600 retail outlets nationwide.
As of late June, around 9.39 million users had replaced their USIM cards, according to SK Telecom.

Vietnamese sex trafficking probe uncovers murder of young woman in remote forest
HAI PHONG, (Vietnam): A police investigation into an illegal sex trafficking ring has led to the discovery of a brutal murder, in which a young woman was beaten to death and her body dumped in a remote forest in northern Vietnam. The police on Friday (July 4) announced that they had completed their case file and handed it over to prosecutors, recommending charges against four suspects. The charges include murder, procuring prostitution, harbouring a criminal, and purchasing sex with a minor. The main suspect, Nguyen Thi Thuy, 43, is accused of both murder and running a prostitution operation. Her husband, Ta Dinh Phuc, 38, faces charges for procuring prostitution. Two others - H Ko Nie, also known as My, 30, and Ngo Xuan Canh, 48 - are accused of harbouring a criminal and purchasing sex with a person under 18, respectively. The case came to light during a broader investigation into a prostitution network allegedly run by Thuy and Phuc. But the investigation took a darker turn when Thuy's 12-year-old son and a 14-year-old girl named Linh came forward, revealing that Thuy had been involved in a murder committed in mid-2024. Under the direction of Bui Quang Binh, the then–Hai Duong's Police Chief (now Hai Phong's Police Chief), a special task force was assembled to investigate. The team faced major obstacles: witnesses had used fake names, many had left the area, and there was no clear information about the victim's identity. It wasn't until investigators interviewed Linh, My, and another witness - a 15-year-old girl from Thanh Hóa - that they located the site where the body had been dumped: a remote forest area in Ban Ngo Commune, Xin Man District, now part of Tuyen Quang Province. However, the victim's identity was still unknown. The only clues were that her name might be Ngoc and that she was from Phu Tho Province. Working with local authorities and comparing old photographs with residency records, police eventually identified her as N.T.K.K., a 30-year-old woman from Phu Tho. According to the investigation, Thuy was awaiting the enforcement of several previous criminal sentences when she opened an eatery called Minh Ngoc in Hai Duong (now part of Hai Phong City). Through online platforms, she recruited young women and girls, forced them into sex work, and housed them in a rented property on Kim Son Street. In April 2024, two girls - K. (the victim) and another teen - were brought in. Because K. was small and thin, Thuy assigned her to work at the restaurant instead of serving clients. Later, two other girls, including Linh and My, joined the operation. K. and another one were responsible for housekeeping duties at the restaurant and dormitory. Over time, K. became a frequent target of Thuy's violence. On the night of July 16, 2024, Thuy accused K. of stealing VNĐ11.5 million (about US$450) from her and My. She allegedly forced K. to undress, beat her with a metal pipe, then wrapped her in a towel and brought her to the restaurant to continue the assault. K. was left naked in the kitchen overnight. The next morning, Thuy reportedly ordered Linh to slap her and pour cleaning fluid over her body. Later, in a final act of brutality, Thuy cut off part of K.'s pinky finger with a knife in an attempt to force a confession. That night, K. died from her injuries. Around midnight, Thuy allegedly forced My, Linh, and another girl named L. to help dispose of the body, threatening to expose their involvement in prostitution if they refused. She packed the body and blood-stained clothes into a car and initially drove toward Quang Ninh. But upon seeing surveillance cameras along the route, she turned back. Early the next morning, the group took the Hanoi–Hai Phong expressway, searching for a more secluded location. Linh searched online and suggested Bac Ha District in Lao Cai Province, but they couldn't find a suitable spot. Eventually, they reached Xin Man District. Near the People's Committee office of Ban Ngo Commune, they dumped the body in a deep pit and began driving home. On the way back, their car broke down in Nam Dan Commune. Based on the investigation, authorities determined that Linh and L., who were both only 14 years old at the time, are not criminally liable under Vietnam's law for helping conceal the crime. The case is now with the People's Procuracy, pending prosecution. - Vietnam News/ANN

Trump Administration Moves To Curb AI Chip Exports To Malaysia, Thailand
The Trump administration is drafting new export controls that would restrict shipments of advanced artificial intelligence (AI) chips from companies like Nvidia Corp to Malaysia and Thailand, in a renewed effort to curb alleged smuggling of semiconductors into China, according to sources familiar with the matter. Bloomberg reported that the draft rule, still under review by the Commerce Department, is aimed at closing loopholes that US officials believe may be allowing restricted chips to reach China via intermediaries in Southeast Asia. The move builds on earlier Biden-era restrictions but reflects a broader push by the Trump administration to tighten control over the flow of critical technology. Under the proposed measure, US chipmakers would face new licensing requirements to export AI processors to the two countries. However, the rule is expected to include temporary exemptions and carveouts for companies based in the US and allied nations, as well as safeguards to avoid disrupting semiconductor supply chains, particularly in chip packaging and assembly, where Southeast Asia plays a vital role. The crackdown comes amid a sharp increase in AI chip shipments to Malaysia and growing US concerns over data centre projects in the region, including those backed by Oracle Corp. Prosecutors in neighbouring Singapore have also charged individuals over alleged misrepresentation of chip destinations, with AI servers possibly rerouted from Singapore to Malaysia. Nvidia, while not implicated, is at the centre of these efforts given its dominance in the AI chip market. Though US allies and tech firms have pushed back on some aspects of the previous AI diffusion rules, Washington appears determined to preserve and strengthen chip curbs targeting China. Commerce Secretary Howard Lutnick recently testified that AI chips could still be sold to allies but only if deployed via US-approved cloud and data centre operators. Malaysia and Thailand have not publicly responded to the draft rule. Nvidia declined to comment. If implemented, the regulation would mark the Trump administration's first formal step in reshaping US AI export policy, one that could have wide-ranging implications for Southeast Asia's growing role in the global semiconductor ecosystem.

‘Digital skills must grow alongside facilities'
KUALA LUMPUR: Malaysia must go beyond developing data centres and ramp up its digital capabilities to stay ahead in a fast-changing global economy, says MCA president Datuk Seri Dr Wee Ka Siong. While the country's data infrastructure is expanding rapidly, he said this growth must be matched with artificial intelligence (AI) development, content creation and the cultivation of local digital talent. 'Accelerating artificial intelligence and developing a skilled digital workforce are essential if Malaysia wants to stay relevant in a fast-evolving digital landscape,' Dr Wee said. He was speaking at the launch of Malaysia's promotion for the Fourth Global Digital Trade Expo (GDTE), to be held from Sept 25 to 29 in Hangzhou, Zhejiang Province, China. Dr Wee, who attended last year's edition of the GDTE, said Malaysian businesses must now embrace 'new retail' models, blending online and offline operations, and adopt digital tools to expand into regional markets. 'Our goal is to move beyond isolated participation and towards systemic engagement, from individual efforts to integrated platforms,' he said. Since its launch in 2022, the GDTE has drawn over 3,500 companies and international organisations from 123 countries, showcasing innovations across AI, e-commerce, digital health, smart logistics and semiconductor technologies. Dr Wee noted that Malaysian companies have already played active roles at the expo as exhibitors, buyers and online collaborators with Chinese firms, and urged more businesses to tap into the opportunities. He stressed that the global economy has fully entered the digital age, and Malaysian industries from manufacturing and exports to services and innovation must assess whether they are adequately prepared. 'This expo provides a national-level platform for Malaysian businesses to connect with the Chinese market, learn from its digital progress and find areas for complementary cooperation rather than becoming trapped in direct competition,' he said. 'It's about collaboration, learning and unlocking opportunities in a fast-evolving digital landscape.' Meanwhile, Chen Wen, chief representative of the Zhejiang Representative Office in Singapore and South-East Asia, described Malaysia as a digital economy pioneer within Asean, noting the country's progress in e-payments, smart logistics, and digital infrastructure. Chen said Zhejiang, home to tech giants like Alibaba and Hikvision, has led China's digital transformation, recording double-digit growth in its digital economy since it was named China's first National Digital Economy Innovation Development Pilot Zone in 2019. In 2024, Malaysia-Zhejiang bilateral trade reached US$16.89bil (RM79.38bil), up 14.9% from the previous year. As of March, Zhejiang companies had invested in 251 projects in Malaysia, with approved investments totalling US$3.03bil (RM14.24bil). Also speaking at the event was Li Sa, Counsellor for Economic and Commercial Affairs at the Chinese Embassy in Malaysia, who praised Malaysia's strong digital infrastructure, supported by the boom in data centre development and an innovative ecosystem that points to a promising market outlook. She expressed confidence about deeper China–Malaysia cooperation in the digital space and urged Malaysian firms to seize the opportunity to participate in the upcoming GDTE. 'China's development will not crowd out neighbouring markets. Instead, it will create an ever-expanding consumer base for them.' She also extended an invitation to Malaysia to attend the China International Import Expo in Shanghai this November. Also present at the event were Secretary-General of the Zhejiang Provincial Chamber of Foreign Contractors He Yun, Malaysia-China Chamber of Commerce president Loo Kok Seong, MCA vice-presidents Datuk Lawrence Low and Datuk Tan Teik Cheng, as well as MCA secretary-general Datuk Chong Sin Woon.
