Business logic vulnerabilities are not code bugs. They are flaws in the design and implementation of an application that allow an attacker to elicit unintended behavior using the application's own legitimate functionality
No scanner finds them. No fuzzer catches them automatically. They require you to understand what the application is supposed to do before you can figure out how to break it
The root cause is almost always the same: developers made flawed assumptions about how users would interact with the application. The attack surface is every place where those assumptions can be broken

Cybersecurity isn’t just tools, it’s mindset, fundamentals, and depth.
⚠️These books may include advanced techniques, use them responsibly.
I don’t promote illegal activity; only test on systems you own or have explicit authorization.
Here are 24 best books across domains you should read 👇🧵
1. The Web Application Hacker’s Handbook:
The go-to manual for web app security, covers XSS, SQLi, auth bypass, and real exploitation techniques.
Critical vulnerabilities doesn't have to be complex or have a CVE - @deepseek_ai publicly exposed their internal ClickHouse database to the world, without any authentication at all, and leaked sensitive data.
No one is safe from security mistakes, follow along to learn more 🧵
A collection of bug bounty insights, from recon to client-side exploitation, along with mindset and efficiency strategies.
This thread is a collection of all the bug bounty articles I’ve shared so far 🧵👇
Just dropped Part 1 of my Recon series on Medium 🚀
I’ll be sharing my methodology + tips & tricks that helped me find real bugs and earn $$$$$

It's never too late to get started with bug bounties! 🤠
Still feeling stuck? These top hackers shared their roadmap on what it takes to become a skilled bug bounty hunter! 😎
A thread! 🧵👇
If you're still using gau or waybackurls, give waymore a try because it will honestly find you waymore endpoints!
It can also download archived responses &you can run xnLinkFinder over the response directory to find even more endpoints, potential params, wordlist + oos domains 🤘
Our bug bounty blog can help you:
> find your first bug (in 2026)
> master most web security vulnerability types (such as XXE, SSRF & XSS)
> learn how to perform deep recon
> develop a unique bug bounty methodology
> write better reports (that pay out more)

When you start on a target, do you just start scanning things or do you stop and think? What is this company? What do they sell/do? What is valuable to them? What would cost them money, negatively impact their business? You need this context, so you know what to look for.
