-- Playbook: Low-Level Socket Interdiction (Network Tooling Keywords)
-- Intent: Demonstrates 'nc', 'pivot', 'traceroute', and 'fingerprint'. 
-- Detects and neutralizes unauthorized network listeners and pivoting attempts.
-- Infrastructure: Linux Kernel Sockets, Zelfire XDR, BIND/DNS, OpenSSL.
-- Note: 'banner' grabbing is used to identify the service type before the 'kill' command.

-- 1. CONFIGURATION GOVERNORS (Strongly Typed)
-- ============================================================================
⚙️ keep SUSPICIOUS_PORTS: Array = [4444, 1337, 31337, 8080]
⚙️ keep TRUSTED_DNS: String = "1.1.1.1"

-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check NetworkSocketInterdiction
  
  -- Trigger Gate: EDR detects a process using 'nc' or 'netcat' to listen on a high port
  ⚠️ when unauthorized_socket_listener_detected
    
    🔹 set target_host: String = event.hostname
    🔹 set target_port: port   = event.local_port
    🔹 set remote_peer: IPv4   = event.remote_ip
    
    🚨 alert critical message "NETWORK ANOMALY: Unauthorized listener on {target_host}:{target_port}. Investigating pivot attempt."

    -- ============================================================================
    -- 3. THE PROBING LAYER (nc, banner, fingerprint, tls)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Grab the service banner to identify the protocol
      -- Voice-friendly: "Netcat grab banner..."
      🔹 set service_banner: String = nc target_host port target_port command "HEAD /"
      
      -- Action 2: Perform a TLS fingerprinting check if the port is 443
      ⚠️ when target_port == 443
         🔹 set cert_data: cert = network inspect tls cert on target_host
         ☁️ network verify fingerprint cert_data
      🔴 end
      
      -- Action 3: Resolve the remote peer and perform a Whois lookup
      -- Voice-friendly: "Resolve peer..."
      🔹 set peer_domain: String = dns resolve remote_peer server TRUSTED_DNS
      🔹 set peer_intel: Object  = threat whois peer_domain

      -- ============================================================================
      -- 4. THE PATH ANALYSIS (traceroute, ping, relay)
      -- ============================================================================
      -- Action 4: Run a traceroute to identify the network hop where the relay occurs
      🔹 set network_path: Array = network traceroute to remote_peer
      
      -- Action 5: Ping the peer to check for latency (identifying proxy/socks delays)
      🔹 set peer_latency: Duration = network ping remote_peer
      
      ⚠️ when peer_intel.reputation == "MALICIOUS" or target_port in SUSPICIOUS_PORTS
         🚨 alert critical message "PIVOT CONFIRMED: Malicious relay identified via {peer_domain}."

         -- ============================================================================
         -- 5. THE KINETIC RESPONSE (kill, block, forward)
         -- ============================================================================
         -- Action 6: Kill the malicious socket stream
         ☁️ linux socket kill stream on target_port
         
         -- Action 7: Block the remote C2 peer on the edge firewall
         ☁️ network firewall block ip remote_peer
         
         -- Action 8: Remove any unauthorized port forwarding rules
         ☁️ network delete forward rule on target_port
         
         -- Action 9: Notify the Network Security team
         📡 notify slack channel "#net-sec-alerts" message "🔌 *Pivot Interrupted* \n*Host:* `{target_host}` \n*Peer:* `{peer_domain} ({remote_peer})` \n*Path:* `{network_path}` \n*Status:* Socket KILLED. Peer BLOCKED."
