An open-source AI agent designed for authorized penetration testing became the shared engine behind breach campaigns in Japan and South Korea within weeks. CrowdStrike linked the tool to a likely Chinese-speaking, financially motivated actor who primarily ran it on DeepSeek v4.1-flash against financial firms in South Korea. This incident highlights the risks of weaponizing open-source security tools and emerging supply chain vulnerabilities.
