Security Intelligence

💡 User-Agent Analysis Techniques

Analyzing User-Agent strings reveals automated tools masquerading as legitimate browsers. Inconsistencies between claimed browser capabilities and actual behavior, impossible version combinations, and known scanner signatures help identify malicious clients.

💡 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.
