我们的监控基础设施已将51.158.37.21(地理位置为Paris, France,运营在SCALEWAY的网络中)识别为可疑网络活动的来源。 在29天的时间内,此IP产生了124次恶意请求,平均每天约4.3次请求。 此地址属于数据中心或云托管提供商。托管IP经常被专门租用廉价VPS实例来进行攻击的威胁行为者利用。 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。 我们的记录显示来自France的2,410个恶意IP,使其成为全球威胁活动的主要贡献者。 评分145/100将此地址置于最高严重性级别。应封锁并调查任何历史连接。
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.
Monitoring DNS queries reveals malicious activity including command-and-control communication, data exfiltration through DNS tunneling, and connections to known malicious domains. DNS is often the first indicator of compromise in network forensics.
