Residing within sensitive networks and lacking in security, these devices represent high-value targets that can theoretically be used not only to manipulate and exfiltrate the sensitive information such as network credentials and sensitive documents, but also as fully functional general-purpose bot-nodes which give attackers a stealthy, persistent foothold inside the victim network for further recognizance, exploitation and exfiltration. 28th Chaos Communication Congress, Berlin, Germany, December 27-30, 2011.
