According to the Arbitrum Security Committee report, in response to the increasingly complex risks of AI-assisted attacks, Arbitrum took emergency action around 23:30 Beijing time on October 2 to temporarily halt the activation of new Stylus contracts on the Arbitrum One and Nova networks.This restriction mainly targets programs and application updates that require new activation, while already activated Stylus applications can continue to operate, and the deployment and execution of regular Solidity contracts are not affected. Arbitrum officials stated that this preventive measure stems from threats of WebAssembly program attacks targeting non-standard Stylus compiler toolchains, and no risk of fund theft has been discovered so far. The main concerns are on-chain activity and denial-of-service (DoS) attacks. Developers can still extend the lifecycle of existing programs through a permissionless keep-alive renewal mechanism, but they cannot activate expired programs or new version applications.

According to a report by the Korean News Agency, South Korea's five major commercial banks have all been suspected of being attacked by hackers possibly driven by artificial intelligence, with three of them experiencing customer information leaks. This simultaneous attack on all five banks is unprecedented in South Korea's financial industry.It is reported that BNK Busan Bank suffered a hacker attack that led to the leakage of personal information of 11 outsourced employees; KB Kookmin Bank had information of 119 customers leaked due to the hacker attack, and Hana Bank also stated that information of 89 customers was leaked.

According to CCTV Finance, the global trade volume of AI-related products will reach 4.18 trillion USD by 2025, a year-on-year increase of 21.9%. With the rapid evolution of artificial intelligence and Agent capabilities, a batch of "portable" AI hardware is accelerating its entry into the consumer market.At the exhibition hall of the Yunqi Conference in Hangzhou, Zhejiang, many AI hardware products, from AI glasses to user-assembled AI DIY devices, no longer solely rely on smartphones. Instead, they synchronize voice, image, and other information around the user in real-time to the Agent, which autonomously breaks down tasks and completes execution. Global investment in AI infrastructure continues to increase, and Chinese technology companies are also making the latest arrangements around AI hardware, large models, and underlying computing power.

The AI wave is breaking the traditional asset diversification logic of pension and sovereign funds, with risks spreading from technology stocks to multiple areas such as private equity, corporate bonds, and infrastructure. Institutional investors are beginning to reassess the AI exposure of their entire portfolios.Goldman Sachs estimates that AI infrastructure-related companies account for about 40% of the total market capitalization of the S&P 500; Apollo data shows that this year, AI-related issuances have accounted for nearly half of the investment-grade bond issuance and 87% of venture capital funding. Monte Tarbox, Chief Investment Officer of the New York City Retirement System, recently rejected a fundraising request due to an overweight position in a private equity fund related to AI.Institutions currently face the challenge of lacking a unified standard for measuring AI exposure. The Los Angeles County Employees Retirement Association estimates that 8% to 19% of its holdings are related to AI; a survey by Invesco of 90 sovereign wealth funds shows that more than half list market concentration as the primary risk of AI investment. Some large institutions are beginning to adopt a holistic portfolio approach to track AI-related exposure and the correlations between assets, while some institutions are starting to use AI tools to monitor their own portfolios.

According to official news, Etherscan has officially released a new toolkit for AI, allowing developers and agents to directly access reliable on-chain data that is the same as that on the Etherscan website.The toolkit covers more than 60 EVM-compatible chains and provides structured, certified real-time data access capabilities for AI agents through three methods: MCP, CLI, and Skills.Among them, Etherscan MCP supports mainstream programming agents like Claude and Codex to query on-chain information in natural language; the CLI tool can output clean JSON, table, or CSV results in the terminal and is equipped with an interactive interface; the Skills module includes professional skills such as Orchestrator, contract review, transaction debugging, and workflow orchestration, helping agents efficiently complete complex tasks.Etherscan stated that these tools are designed to lower the barriers for AI to interact with blockchain data, allowing developers to quickly get started by directly pointing to the official documentation, while also welcoming user feedback on their experience or sharing innovative applications built using these tools.

Tencent Interactive Entertainment Group (IEG) is integrating ARC Lab and the Game AI Engine Department to establish a new AI gaming department (tentatively named ARC Lab), led by Chen Dong, the head of Tencent Games Public Technology. The aim is to explore AI-native games. The department currently has about 100 people, with plans to expand to 400 to 500, and is actively recruiting on a large scale for top multimodal generation teams, covering areas such as audio and video foundational models, video world models, Agents, etc.According to informed sources, the early formation model of the department references the talent and data supply chain paths of Seedance and Keling, focusing on exploring the possibility of directly generating games from video models. Tencent IEG has a cash flow of 130.1 billion yuan in game revenue for the first half of the year and approximately 10,000 H card computing power reserves, as well as exclusive game data that cannot be accessed by the mixed Yuan large model. Currently, Tencent's AI game development is showing a parallel multi-system situation: TEG provides basic capabilities, the IEG middle platform integrates tools, and the four major studios are advancing independently, with no unified standards yet. The specific organizational structure is still being refined, and the final plan will be subject to official announcement.
