日本企业近期遭遇前所未见的大规模网路攻击浪潮，受害对象涵盖大和证券、软银旗下云端子公司、JR东日本、便利商店罗森以至餐饮娱乐业者。根据统计，日本今年前九个月公开通报的资安外泄事件已超越去年全年总额，且微软报告显示当地的勒索软体攻击逆势激增67%，恶名昭彰的俄语骇客组织Qilin更警告未来攻击还将持续攀升。

此波资安危机的关键在于新型人工智慧工具显著降低了发动攻击的成本与门槛，使攻击者能自动化且密集地大规模扫描并利用旧有系统漏洞。尽管日本政府紧急召集跨部会会议并提醒业界提高警觉，但现有应对指引仍停留在检视日志与打补丁等传统防御思维，而占日本企业达99%的中小企业普遍严重缺乏防护能量与专业人才，极易成为供应链攻击的薄弱破口。

这场结合AI技术的网路攻击风暴绝非日本独有，近期南韩主要银行、法国连锁超市冷藏系统及澳洲政府健康门户网站均相继遭殃。各国政府与民间必须加速跨国情报共享，而AI技术开发商亦应承担责任，协助防范产品被滥用并为防御方提供支援，唯有将网路韧性视同天然灾害防救般落实标准化，才能应对AI时代日益严峻的资安威胁。

Japan Inc. has been struck by an unprecedented wave of cyberattacks in recent weeks, impacting a wide array of organizations including Daiwa Securities, SoftBank's cloud unit, JR East, convenience store chain Lawson, and everyday consumer businesses. Publicly disclosed breaches in Japan through September have already surpassed the total for all of last year, with ransomware incidents surging by 67% according to Microsoft, while the notorious Russian-speaking group Qilin warned that assaults on the country are poised to escalate.

The severity of this crisis stems from new artificial intelligence tools that have lowered costs and technical barriers, allowing threat actors to automate relentless carpet-bombing campaigns targeting legacy vulnerabilities. Although Tokyo quickly convened cross-ministry meetings and issued alerts to industry bodies, existing government guidance remains largely superficial, leaving the nation's vast network of small and medium-sized enterprises—which comprise 99% of businesses and suffer severe talent shortages—vulnerable to widespread supply chain disruptions.

This surge in AI-supercharged threats is a global test rather than an isolated Japanese issue, underscored by concurrent attacks on South Korean financial institutions, French supermarket infrastructure, and Australian government portals. Governments and the private sector must urgently establish cross-border information-sharing frameworks, while AI providers must take responsibility for curbing tool abuse and empowering defenders to build systematic cyber resilience akin to natural disaster preparedness.
