Web Hacking

Insecure deserialization has handed attackers RCE in some of the most hardened enterprise environments on the planet — Apache, Jenkins, JBoss, WebLogic, Oracle, and more. A single malformed object can bypass authentication, execute arbitrary code, or delete your entire database. This guide covers detection, exploitation, gadget chains, and WAF bypass for Java, PHP, Python, and .NET in 2026. What Is Deserialization? Serialization converts an object in memory into a format that can be stored or transmitted — bytes, JSON, XML, binary. Deserialization reverses it: takes the stored format and reconstructs the object. ...

Server-Side Template Injection (SSTI) is one of the most dangerous web vulnerabilities you’ll encounter. A simple {{7*7}} in the right field can hand you full remote code execution on a production server. This guide covers everything — detection, fingerprinting, exploitation, WAF bypass, and defense — for every major template engine in 2026. What Is SSTI? Web frameworks use template engines to render dynamic content — think Flask with Jinja2, PHP apps with Twig, Java apps with FreeMarker. When user input is concatenated directly into a template string rather than passed as a variable, the template engine evaluates it. That’s SSTI. ...

Web application pentesting is where most red teamers spend the majority of their billable hours. It’s also where a huge chunk of real-world breaches happen — not through exotic exploits, but through the same OWASP Top 10 vulnerabilities that have existed for decades. This guide covers the full methodology: reconnaissance, mapping the attack surface, exploiting common vulnerabilities, and reporting findings. Whether you’re doing your first web pentest or sharpening your methodology for bug bounty, this is the process. ...
