Preventing unauthorized access through session hijacking requires a a layered defense strategy and system-level protections. Session theft occurs when an malicious actor compromises a user’s access token to impersonate them and gain unauthorized access without credential knowledge. This exploit can be triggered via public Wi-Fi hotspots, XSS attacks, or insecurely handled session cookies.

To defend against this threat, web platforms and services must use secure, encrypted connections at all times. This guarantees that authentication credentials are protected from eavesdropping and cannot be easily intercepted on untrusted networks. Moreover, session tokens need to be reissued immediately post-authentication to block token reuse exploits.
