Security Intelligence

💡 TLS Fingerprinting (JA3/JA4)

TLS fingerprinting creates unique identifiers based on how clients negotiate encrypted connections. The JA3 and JA4 methods generate hashes from TLS ClientHello parameters, enabling identification of specific tools and malware regardless of IP address changes.

💡 State-Sponsored Cyber Operations

Nation-state actors conduct sophisticated campaigns for espionage, sabotage, and influence operations. Their resources exceed typical criminal organizations, enabling zero-day exploitation, long-term persistent access, and attacks on critical infrastructure.
