Marco Santambrogio and Stefano Zanero. Federico's research interests revolve around collecting data from public sources to analyze and explain malicious activities. These include Android malware, botnets, and web service and social network abuses, on which he has published tenths of peer-reviewed articles at international venues. During his PhD, obtained in 2010 at Politecnico di Milano, he studied and made contributions in the field of anomaly-based intrusion detection, developing and evaluating machine-learning based approaches to detect unexpected network payload at the network and application (e.g., HTTP) layer, and on the Linux kernel (e.g., system calls).
