威胁情报分析将216.73.216.21与来自Columbus, United States,运营在Amazon.com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。 该地址在我们的监控系统中活跃了54天,产生了7次标记请求,速率约为每天0.1次。 该IP被归类为托管/数据中心基础设施,通常与用于自动化攻击活动、僵尸网络命令控制或大规模漏洞扫描的租用服务器相关联。 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。 United States目前在我们的数据库中占180个被封锁IP,使其成为恶意流量的重要来源。 评分65/100需要主动监控和速率限制。建议对敏感系统进行完全封锁。
This IP belongs to a hosting or data center provider. Malicious traffic from hosting infrastructure often originates from compromised VPS instances, rented servers used for scanning campaigns, or abused free-tier cloud accounts. Hosting providers typically respond to abuse reports within 24-72 hours.
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.
DNS sinkholing redirects queries for known malicious domains to controlled IP addresses. This technique blocks malware communication, prevents data exfiltration, and identifies compromised internal hosts attempting to contact command-and-control servers.
