  • NTP amplification methods
• Protocol Attacks:
  • SYN flood variations
  • TCP state exhaustion
  • ICMP protocol exploitation
  • Fragment attacks targeting network resources
• Application Layer Attacks:
  • HTTP/HTTPS flood attacks
  • Slow POST/GET requests
  • API endpoint targeting
  • Resource exhaustion through complex queries
