Fundamentals SQL Injection (SQLi) occurs when an attacker can influence the SQL statements that an application sends to its database. The vulnerability arises from the unsafe concatenation of untrusted input into a query string, allowing the attacker to break out of the intended data context and execute attacker-controlled SQL. SQLi has sat in the OWASP Top Ten since its inception and remains one of the highest-impact classes of web vulnerability despite decades of awareness. ...

Fundamentals Cross-Site Request Forgery (CSRF / XSRF / “sea-surf”) is an attack that tricks an authenticated user’s browser into submitting a state-changing request to a target application. The victim’s browser automatically attaches ambient credentials — cookies, HTTP Basic auth, client certificates, Kerberos tickets, IP-based authorization — so the target application cannot distinguish a forged request from a legitimate one. ...

Fundamentals Insecure deserialization occurs when an application reconstructs program objects from attacker-controlled data without sufficient validation. Serialization converts an in-memory object graph to a byte stream for storage or transit; deserialization reverses the process. The danger is that most native serialization formats are not just data — they are instructions for how to rebuild arbitrary objects, including which classes to instantiate and which methods (constructors, magic methods, callbacks) to run along the way. ...

Fundamentals & Threat Model Mobile application security differs from traditional web security in three material ways. First, the attacker has the binary on their device and can take it apart at leisure — the app runs in a fundamentally hostile environment. Second, the OS provides strong sandboxing, code signing, and hardware-backed keystores that raise the bar but can be bypassed by a motivated attacker on a rooted or jailbroken device. Third, the attack surface spans the binary, the device, the local IPC boundary, the network, and the backend APIs — any of which can be the weak link. ...

Fundamentals Recon is 80% of offensive security. The researchers who earn six figures aren’t running more tools than everyone else — they’re running them in smarter pipelines, feeding the output of one into the next, and manually reviewing the long tail that automation misses. Every hour spent deepening the asset inventory pays off when hunting begins: more subdomains means more parameters, more endpoints, more code paths, more chances for a bug nobody else has seen. ...
