Part 1 : Hunting Vulnerabilities in Smart contracts
So first how smart contracts works ? 🤔
The best way to understand that is by imagining a vending machine. Each and every step that you take acts like a trigger for the next step to execute itself. So, let’s examine the steps that you will take while interacting with the vending machine:
Now look at all those…
Basic Cross Site Request Forgery
CSRF (Cross site request forgery) is the vulnerability that tricks the user to submit the malicious request if there is no implementation of the Anti-CSRF tokens in the forms or site. When implemented your website https://example.com will include a random generated number or token to every page which is impossible to guess by the attacker so https://example.com will include it when they serve it to you. It differs each time they serve any page to anybody so attacker won’t be able to generate a valid request because of the wrong token.

Hello, Guys, I m back with a new Story on bug bounty, I found this bug last year on AT&T bug bounty program (Now its H1 Program), thought of sharing it
So here I would like to share how I got 1000$ for reporting CSRF vulnerability in AT&T which Leads to user account takeover
here you will get to know the importance of Account Takeover 👊:v:) ,
So here’s how it went on, earlier during my engineering 3rdyear, I had too much free time, That time my daily schedule was like,

I’m going to talk about a common and strange password reset system that I have seen many times in Bug Hunting and in many VAPT projects. and in many cases this system opens the door to attacker to hack user’s accounts.
The story started when I was testing Change password function on this website but I found something interesting. After I changed my password successfully via Change Password Functionality, I noticed the following request:
