Session poisoning

Imagine you had a cookie and you were sharing it with your friend. But then, another person came along and wanted a piece of your cookie. You didn't know this person and they seemed suspicious. They might try to take your whole cookie or even poison it.

In a similar way, when you visit a website, the website gives you a cookie. This cookie is like a virtual ID card that lets the website remember who you are and what you’ve done on the website.

But sometimes, hackers can hack into the website and change this cookie to their own ID card. This is called session poisoning. Now, the website thinks that the hacker is you, and they can do anything that you could do on the website, like edit your account details or make purchases using your payment details.

That's why it's important to be careful when visiting websites and to make sure you don't click on suspicious links or enter personal information on untrusted websites.
