一句话：系统观察活跃 IoT 攻击者滥用各类系统资源的行为与恶意意图，为防护策略提供依据。
近年来，IoT 设备频繁遭受攻击并造成严重影响。已有研究多通过离线样本分析揭示特定恶意软件家族或攻击阶段的特征，但仍缺乏对活跃攻击者滥用各类系统资源的系统性观察，也缺乏对其恶意意图的理解，这阻碍了防护策略的设计。本文针对这一空白开展实证研究，以活跃 IoT 攻击者为观察对象，系统分析其滥用的系统资源类型、行为模式与潜在意图，并讨论发现对安全防护的启示。摘要未给出具体实验设置与量化结果，核心贡献在于从系统资源滥用视角提供系统性观察，帮助理解 IoT 攻击行为并设计更适配的保护机制。
IoT devices have been under frequent attacks in recent years, causing severe impacts. Previous research has shown the evolution and features of some specific IoT malware families or stages of IoT attacks through offline sample analysis. However, we still lack a systematic observation of various system resources abused by active attackers and the malicious intentions behind these behaviors. This makes it difficult to design appropriate protection strategies to defend against existing attacks and possible future variants.
