#! Anatomy of a Bug
Autopsy of a Zero-Day. High-fidelity technical analyses of critical vulnerabilities, kernel exploits, and architectural failures.
📜 Manifesto
#! Anatomy of a Bug is a weekly research series dedicated to deconstructing the most sophisticated exploits in the wild. We move beyond the “what” and focus on the “how” and “why.”
Each report follows a strict forensic structure:
- The Patient: The target system and its architectural context.
- The Diagnosis: The precise root cause (e.g., Integer Overflow, Race Condition, Logic Flaw).
- The Kill-Chain: Step-by-step reconstruction of the exploit flow (from entry to root/kernel).
- The Fix: Code-level remediation and developer takeaways.

🔬 Methodology
This repository serves as a knowledge base for Exploit Developers, Security Researchers, and Reverse Engineers. The goal is not just to document the vulnerability, but to understand the mindset of the attacker and the design failures of the defender.
Tools and techniques often referenced:
- Static Analysis: Binary diffing, control flow graph reconstruction.
- Dynamic Analysis: Kernel debugging, heap spraying visualization.
- De-obfuscation: Unpacking custom malware layers and polyglott payloads.
