A firewall blocks all outbound traffic except DNS, yet an infected server is still sending data out, hidden inside large numbers of unusual DNS queries for random-looking subdomains. What technique is this?
Un pare-feu bloque tout le trafic sortant sauf le DNS, et pourtant un serveur infecté continue d'envoyer des données vers l'extérieur, cachées dans un grand nombre de requêtes DNS inhabituelles pour des sous-domaines à l'apparence aléatoire. De quelle technique s'agit-il ?
