Core Viewpoint - The recent cyber attack on Kuaishou highlights the urgent need for effective responses to cybersecurity threats, with cybersecurity insurance emerging as a potential solution to mitigate financial losses from such incidents [1][3]. Group 1: Cybersecurity Insurance Overview - Cybersecurity insurance can compensate for direct economic losses caused by cyber attacks, including those from black and gray market activities, although the specific coverage and conditions depend on the policy terms [3][4]. - This type of insurance serves as a risk management tool that combines insurance mechanisms with security technology, allowing companies to transfer some cybersecurity risks and reduce their security investment burden [4][10]. - The market for cybersecurity insurance is growing, with innovative products emerging that cover various areas such as network financial account security, virtual asset security, mobile payment security, and cloud service security [5][6]. Group 2: Types of Cybersecurity Insurance - Cybersecurity insurance in China primarily includes two categories: cybersecurity property insurance and cybersecurity liability insurance [5][6]. - Cybersecurity property insurance covers first-party direct losses from cyber incidents, including physical damage, business interruption losses, data asset reset costs, and related legal expenses [5][6]. - Cybersecurity liability insurance protects against third-party claims arising from cyber incidents, such as data breach liabilities and media infringement responsibilities [6]. Group 3: Challenges in Cybersecurity Insurance - The insurance industry faces challenges in underwriting and claims processes, including difficulties in risk assessment due to a lack of historical data and the rapid evolution of internet technologies [8][9]. - Defining insurance responsibilities is complicated, as terms like "cyber warfare" and "terrorist acts" often lack clear definitions, making it hard to determine liability in cyber incidents [8][9]. - The current contracts for cybersecurity insurance need to be more standardized, particularly regarding the coverage of consequential losses affecting supply chain partners [9]. Group 4: Future Directions for Cybersecurity Insurance - To enhance the reliability of cybersecurity insurance, collaboration across the industry is essential, including partnerships between insurance companies, cybersecurity firms, and research institutions to develop better risk assessment models [10]. - Insurance providers should ensure clarity in policy terms and definitions to avoid disputes and improve communication with policyholders [10][11]. - There is a need for data sharing among industry and government entities to support pricing and the development of external technical support for cybersecurity insurance [10].

Core Viewpoint - The incident involving Kuaishou's live streaming platform highlights vulnerabilities in internet security, particularly regarding automated attacks from black and gray market operations, leading to significant content violations and market concerns [1][2][3]. Group 1: Nature of Black and Gray Market Attacks - Black and gray market operations refer to illicit and borderline illegal activities that manipulate online ecosystems, particularly in live streaming and e-commerce [2]. - These attacks often involve automated tools for mass account registration and content manipulation, which can overwhelm traditional human review processes [3][5]. - The recent Kuaishou incident involved the use of 17,000 bot accounts, showcasing the scale and sophistication of such attacks [4].
