Recommendations

Actions taken & recommended

  • IP 104.28.152.155 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 104.28.152.0/24
  • Report abuse to the network provider via their abuse contact
  • Ensure sensitive files (.env, .git, backups) are not accessible from the web

🔎 Path Enumeration Protection

Block scanning from 104.28.152.155: rate-limit 404 responses per IP, deploy a honeypot 404 page, ensure no backup files are web-accessible.

🌊 Flood / DDoS Mitigation

Implement limit_req_zone in nginx. Deploy CDN with DDoS protection. Configure SYN cookies and connection tracking to throttle 104.28.152.155.

🤖 Bot Detection

Address UA spoofing from 104.28.152.155: maintain blocklist of known malicious UA strings, require consistent UA across sessions, implement TLS fingerprinting.

Security Intelligence

💡 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.

💡 DNS Amplification Attack Mechanics

DNS amplification exploits open resolvers to reflect and amplify traffic toward victims. A small query triggers a large response directed at the spoofed source IP, achieving amplification factors of 50x or more, overwhelming target bandwidth.
