• Linux Forensics: Finding Attacker Traces After a Breach

    After a breach, every minute of attacker dwell time costs you. This post walks through two immediate Linux forensic checks — hunting rogue accounts and recovering shell history — with real commands and output so you know exactly what to look for.

  • AI-Generated Polymorphic Malware: How It Works

    AI-generated polymorphic malware uses local LLMs to rewrite its own code every few seconds, defeating signature-based detection entirely. Learn how the mutation engine works, what it looks like in EDR telemetry, and which behavioral indicators actually catch it.

  • Reverse Engineering CTF Challenges with Ghidra

    Ghidra cuts through CTF reverse engineering challenges by turning compiled binaries into readable pseudocode. This walkthrough shows you exactly how to find flag logic — including XOR-obfuscated variants — using real decompiler output and one-line Python decodes.

  • Hashcat GPU Cracking: Complete Setup & Usage Guide

    Hashcat turns a modern GPU into a password cracking engine capable of billions of hash comparisons per second. This guide walks through installation, device verification, dictionary attacks, and rule-based cracking with real commands and output you can follow step by step.

  • Rootkit Techniques & How to Detect Them

    Rootkits stay hidden by lying to the OS itself — but the kernel’s raw data structures don’t lie. Learn how to spot hidden processes via /proc, detect tampered binaries with rkhunter, and expose LD_PRELOAD hijacking in minutes.

  • XXE Injection: XML External Entity Attack Techniques

    XXE injection abuses XML parsers that resolve external entities, letting attackers read local files and exfiltrate data out-of-band. This post walks through a direct file-read attack and a blind OOB exfiltration technique with real payloads and tool output.
