[Key Issue Briefing]
■ As AI Agents Spread, So Do Hacking Vulnerabilities: Prompt injection attacks, which exploit a structural trait of AI agents that cannot distinguish user commands from external data, are becoming a real threat. South Korea's personal data regulatory friction score stands at 70.4 out of 100, higher than the 63 recorded by European Union member states, prompting warnings that it could hold back the country's AI industry.
■ Lunchflation Pushes Office Workers to Convenience Stores: Restaurants where a meal can be had for 10,000 won account for just 20.1% of all eateries. As dining-out costs mount, sales of convenience store ready meals and fast food are surging by double digits or more.
■ Preference for Jobs Deepens Shortage of Basic Science Talent: From the 2022 academic year through this year, 41.4% of graduate admissions units in the sciences and engineering at Seoul National University drew fewer applicants than available seats. As more students opt for quick employment and higher pay, concerns are growing that the foundation for training basic science researchers is being eroded.

Key points: Kim Byung-pil, a professor at KAIST, explained that prompt injection — in which hackers plant malicious instructions to manipulate an AI agent — is the single biggest security threat, because agents read user instructions and external content stitched together on a single work surface. In a survey of 34 AI companies, 78.8% said compliance with consent requirements for collecting and using personal data was a heavy burden, and 48.5% said they had given up on obtaining data they needed because it was unclear whether doing so was legally permitted. South Korea's personal data regulatory friction score of 70.4 out of 100 was the highest alongside China's and exceeded the 63 recorded by EU member states. Experts proposed spelling out the purpose of processing and the legal basis for it when linking to outside services, and designing regulatory obligations on a graduated scale according to the level of risk.
2. Even Kalguksu Tops 10,000 Won — Diners Head to Convenience Stores and Cafes for a Cheap Meal
Key points: According to a Ministry of Agriculture, Food and Rural Affairs survey of restaurant operations, the share of eateries with an average check of less than 10,000 won was 20.1% last year, down 3.3 percentage points from 23.4% in 2024. The average price of kalguksu in Seoul topped 10,000 won for the first time in March this year, and prices rose for all eight major dining-out items surveyed, including gimbap, samgyetang and naengmyeon. Sales of GS25 ready meals such as lunch boxes, gimbap and rice balls grew 24.1% in the first half of this year from a year earlier, while McDonald's Korea posted revenue of 1.4313 trillion won last year, up 14.5%. Even after raising prices, restaurants saw operating costs climb faster, pushing their operating margin down to 8.8% from 9.1%, and the industry expects upward pressure on dining-out prices to persist for some time.
3. Even Seoul National University Shuns Basic Science — Four in 10 Graduate Programs Fall Short
Key points: According to the office of Rep. Jung Sung-kook of the People Power Party, 376 of 909 graduate admissions units in the College of Natural Sciences and College of Engineering at Seoul National University, or 41.4%, drew fewer applicants than seats from the 2022 academic year through this year. Seventy-nine admissions units received no applicants at all. Shortfalls were most pronounced in basic science fields such as chemistry and earth and environmental sciences, while an AI program attracted 48 applicants for 11 seats, a ratio of more than four to one. As the belief spreads that two years of employment at Samsung Electronics or SK hynix pays more than a professor's salary, more students are dropping out of or abandoning doctoral programs. Experts stressed the need for practical measures, including more quality jobs for doctorate holders along with better scholarships and research conditions.

4. [Exclusive] 'ETF Trust Fees Twice Those of Brokerages' — Banks Must Now Tell Customers
Key points: The Financial Supervisory Service has distributed its 2026 plan to improve rules on non-deposit products at banks, requiring banks to inform customers of the fee gap between ETF trusts and buying directly through a brokerage. Bank trusts offer consultation and follow-up management services, but the added trust fee makes them more than twice as expensive as brokerages, and they also cannot offer real-time trading or limit orders. Regular notices at least once a month are now mandatory for products rated at investment risk levels 1 and 2, and banks must report valuations and returns as needed when prices swing sharply. The industry voiced concern that the mandatory fee comparison could weigh on bank sales of ETF trusts.
5. LH Declares 'AI Transformation,' Creating Dedicated AI Innovation Bureau
Key points: Korea Land & Housing Corporation has elevated AI to a core management agenda, holding a ceremony to declare the "LH AI Transformation" presided over by CEO Lee Sung-hoon, and formalizing plans to create a dedicated organization called the AI Innovation Bureau. The corporation has already used AI to cut the time needed to handle construction defects by 31%, to 12.5 days from 18, and expects an in-house AI knowledge system to save 10,833 working hours a year. The number of people covered by its AI care calls expanded more than sevenfold, to 9,400 this year from 1,200 last year. By building an operating framework in which the CEO directly drives and reviews AI transformation, the company has made clear a state-run institution's commitment to AI-driven management innovation.
6. Beyond Shipbuilding to AI Data Centers and Nuclear — HD Hyundai Broadens Its Growth Pillars
Key points: Chung Ki-sun, who marked his first anniversary as HD Hyundai chairman, has rapidly broadened the group's business footprint into future energy markets such as power infrastructure for AI data centers and next-generation nuclear reactors. The group posted revenue of 42.0113 trillion won and operating profit of 6.9594 trillion won in the first half of this year, its best results since its 2018 launch, while cumulative orders for its HiMSEN power generation engines for AI data centers topped 1.5 trillion won. In all, it has poured 1.4037 trillion won into new energy infrastructure businesses, including 238.6 billion won for small modular reactor facilities. Still, orders for special-purpose vessels in the first half came to just 12.1% of the annual target, and labor disputes and on-site safety management remain immediate challenges.
