Session hijacking relies, in part, on many of the prerequisites needed to successfully sniff a network. For instance, session hijacking attacks increase in complexity for external and switched networks. In other words, sitting on the local LAN (for example, as a disgruntled employee) is a much better strategic position for an attack than sitting outside … Read more
Network-level session hijacking is a hijacking method that focuses on exploiting a TCP/IP connection after initialization or authentication has occurred. There are some specific hijacking techniques that are in this category of attack. Some common ones we will discuss are TCP/IP hijacking, man-in-the-middle attacks, and UDP session hijacking. TCP/IP Session Hijacking TCP/IP session hijacking is … Read more
