The latter have quickly become attractive to Internet users, who often consider pure P2P as more \"Secure\" than hybrid systems (i.e. with some central entity). In this paper, the authors concentrate on some relevant security threats and performance inefficiencies in the Gnutella P2P network, which is worldwide, the most popular fully decentralized sys-tem.
