Timeline
Recommendations
Actions taken & recommended
- IP 91.92.43.152 is blocked at application level (HTTP 403)
- Consider blocking at firewall level (iptables/CSF) to reduce server load
- Other malicious IPs detected in the same /24 subnet — consider blocking 91.92.43.0/24
- Ensure sensitive files (.env, .git, backups) are not accessible from the web
🔎 Directory Scan Defense
IP 91.92.43.152 is enumerating directories. Configure fail2ban apache-404 jail after 10+ 404 errors. Disable directory listings. Normalize all 404 responses.
🌊 Flood / DDoS Mitigation
Implement limit_req_zone in nginx. Deploy CDN with DDoS protection. Configure SYN cookies and connection tracking to throttle 91.92.43.152.
🤖 Bot Detection
Address UA spoofing from 91.92.43.152: maintain blocklist of known malicious UA strings, require consistent UA across sessions, implement TLS fingerprinting.

📊 Threat Analysis
Our monitoring infrastructure has identified 91.92.43.152, geolocated to Amsterdam, Netherlands, operating on the network of Dedik Services Limited, as a source of suspicious network activity. During its 4-day observation window, we recorded 284 hostile requests from this IP — roughly 71 per day on average. The address operates as a VPN/proxy exit node. Attackers route traffic through anonymizing services to obscure their real location and evade IP-based security controls. The combination of 3 distinct attack vectors indicates a sophisticated, multi-pronged threat actor deploying automated tools that probe multiple attack surfaces simultaneously. Our records show 23 malicious IPs originating from Netherlands, positioning it as a notable contributor to global threat activity. At 358/100, this is an extremely high-risk address. All traffic should be considered hostile.
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.

💡 DDoS Mitigation Approaches
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.
💡 Satellite Internet Security
Satellite internet introduces unique security challenges including high latency that affects real-time threat detection, shared bandwidth that enables traffic sniffing, and coverage areas that cross multiple jurisdictions complicating legal response.
