【#快手被黑灰产攻击原因# 】#黑灰产已迈入自动化攻击时代# 多家网络安全公司发文回应"快手被黑灰产攻击"一事。 360安全专家分析称，近年来，互联网黑灰产攻击态势持续演进，呈现出隐蔽性增强、智能化提升及产 业化程度加深的发展趋势。特别是伴随人工智能技术的快速发展，黑灰产攻击日益呈现AI化特征。一 方面借助AI手段显著提升其攻击效能，另一方面利用AI生成海量不实或有害内容以加剧信息泛滥，两 者往往协同作战，形成立体化威胁。 奇安信安全专家汪列军向智通财经记者表示，此次攻击之所以能造成大规模破坏，核心原因在于黑灰产 已全面迈入 "自动化攻击" 时代，而平台仍依赖传统人工防御模式。黑客借助自动化工具批量注册、操 控僵尸号，实现违规内容的秒级发布与扩散，这种规模化攻击完全超出人工审核的应对极限。 传统人工审核存在天然滞后性，面对每秒数十条的违规内容洪流，往往陷入 "封禁不及新增" 的被动局 面，即便增派人手也难以填补攻防效率差。黑灰产利用技术工具降低攻击门槛，形成 "攻击自动化" 与 "防御人工化" 的不对称对抗，传统防护体系在这种降维打击下形同虚设，这也是此次快手服务器瘫 痪、违规内容泛滥的关键症结。（智通财经） ...
