威胁情报分析将149.5.4.246与来自Amsterdam, Netherlands,运营在Solid Systems LLC的网络中的恶意活动相关联。该地址自首次检测以来一直处于观察状态。 在其4天的观察窗口期间,我们记录了来自此IP的266次敌对请求——平均每天约66.5次。 该地址被归类为住宅,意味着它可能属于终端用户ISP连接。来自住宅IP的恶意活动通常表明设备已被入侵或属于僵尸网络。 识别出两种攻击模式(Request Flooding和User-Agent Anomaly),表明这是一个针对多个漏洞的半自动化攻击活动。 威胁评分70/100将此IP置于高风险类别。建议在防火墙级别进行封锁。
This IP is classified as residential, suggesting it may belong to a compromised home device, IoT botnet member, or an infected personal computer. Residential IPs involved in attacks often indicate malware infection without the owner's knowledge.
Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.
Cross-Origin Resource Sharing misconfigurations can expose sensitive APIs to unauthorized origins. Wildcard policies, reflected origins, and null origin allowlisting create vulnerabilities that attackers exploit for data theft and unauthorized actions.
