Sapphire Ticket attacks exploit Kerberos authentication by leveraging S4U2Self and User-to-User (U2U) protocol extensions, enabling attackers to impersonate high-privilege users. These attacks involve obtaining a legitimate TGT, manipulating the PAC, and creating forged tickets. Detecting and preventing such attacks requires monitoring ticket behavior, securing KCD configurations, and minimizing NTLM usage.
