AI 网络攻击成新趋势：2025 Q4 攻击样本预测试 2026 AI安全风险

Security reports show that in the fourth quarter of 2025 there were multiple cases of cyberattacks utilizing autonomous AI Agents, with attackers significantly expanding their attack surface by automating intelligence gathering, lateral movement, and elevation of privilege through the intelligences. Some analyses point out that some national-level threat actors have already used AI Agents to execute the steps of the 80%-90% attack chain in actual combat, with speed and covertness exceeding that of traditional human hacker teams. Experts predict that, as big models and automation frameworks sink further, "autonomous AI attacks" could evolve into a new mainstream threat in 2026 that is more destructive than traditional ransomware and spear phishing, especially targeting critical infrastructure and cloud environments.
