172.71.148.21 has been assigned a threat score of 85/100 (Critical). 如此高的分数标志着一个关键威胁行为者。该地址在多个检测向量上表现出持续的、激进的恶意行为。
The following attack categories were identified:
地址172.71.148.21来源于Frankfurt, Germany,运营在Cloudflare, Inc.的网络中。它是通过对受监控端点的入站网络流量进行自动分析而被识别的。 该地址在我们的监控系统中活跃了4天,产生了859次标记请求,速率约为每天214.8次。 该地址作为VPN/代理出口节点运营。攻击者通过匿名化服务路由流量以隐藏真实位置。 识别出两种攻击模式(Path Enumeration和Request Flooding),表明这是一个针对多个漏洞的半自动化攻击活动。 我们的记录显示来自Germany的193个恶意IP,使其成为全球威胁活动的重要贡献者。 威胁评分85/100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 associated with a VPN or proxy service. Attackers frequently route their traffic through anonymizing services to obscure their true location. This makes attribution more challenging but the malicious behavior patterns remain detectable.
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.
Effective rate limiting must balance protection against abuse with allowing legitimate traffic bursts. Sliding window algorithms, token buckets, and adaptive thresholds based on client reputation provide layered defense against flooding attacks.
