![]() Of course I am also presuming that you are in complete control of everything that is transmitted to the user's browser as part of "your" web-page. ("Peanut Gallery™, please chime in here" – Does it?) During session hijacking, you'll also be working on the same server at the same time as your attacker (until the program crashes or you're removed from it). Manipulating the token session executing the session hijacking attack. ![]() Explore common cybersecurity terms and definitions to help you uncover knowledge areas in which you excel and where you want to expand. In the example, as we can see, first the attacker uses a sniffer to capture a valid token session called Session ID, then they use the valid token session to gain unauthorized access to the Web Server. And, so far as I recall, the existing PHP session-handling logic already considers this. During a spoof, your hacker impersonates you and starts a new session without your knowledge. Man-in-the-middle attacks (MITM) are a type of cybersecurity attack in which the attacker eavesdrops on a communication between two other parties without being detected. The only credible "attack" would therefore be that a still-current ID would somehow be stolen by an evil-person who necessarily would be launching their legitimate attack from a different IP-address. The session-ID "nonce" is fundamentally a random value, within a numeric space so vast that "brute-force" would never actually work. If I decide to eat dinner before responding to a web-site, and especially if I have a nice glass of wine with that dinner, then there's a very(!) good chance. I would be of the opinion that, yes, "these attacks are so unlikely that such measures are not necessary." In fact, they probably aren't "attacks" at all.
