Hack4: Attacks on VoIP Infrastructures

Communication using Voice over IP has been common practice for a long time and is found in many business divisions. In addition to traditional telephony, audio and video conferencing, chat functions, softphones, but also, for example, communication via browsers pose current challenges for this kind of communication. This combination of communication options is known as Unified Communication (UC). However, the resulting, partly highly complex UC scenarios are risky and can severely threaten the bordering company infrastructure.

The perspective of an attacker will be adopted during a two-day workshop. The participants will eavesdrop conversations, crack encryption processes, circumvent protection measures, gain access to devices and systems, as well as escalate their privileges. The workshop shall provide a deeper insight into the methods of attackers so that participants can subsequently identify, assess and minimize the risks in their own network. Theoretical concepts will be explained and learned attack vectors tested by means of practical "hands-on" exercises.
