On May 14 2014, the ISUS unit promoted a Workshop on the theme “Computer Networks Security” which intended to introduce and demonstrate the major vulnerabilities of current wireless encryption protocols (e.g. WEP and WPA) and secure communication protocols (e.g. HTTPS/SSL). These technologies are commonly used in private and public infrastructures and thus may compromise the entire infrastructure without proper usage. The workshop addressed a series of attacks carried out in a controlled environment by simulating a legitimate computer victim connected to a WiFi network infrastructure; the attacks were prepared to demonstrate, for example, how easy existing vulnerabilities can be exploited to access the protected WiFi network and hack https requests issued from the victim computers thus granting the attacker access to all the information exchanged by that computer (even when the misleading victim considers itself protected by secure protocols).
