Lazarus Group shipped payloads that beat five AV engines in 2025 — not through novel exploits, but through layered obfuscation. This post walks through Base64 decoding, XOR brute-forcing, and unpacking PE files with real commands so defenders can dismantle these techniques on the spot.
Most defenders have the CVE number but no idea what the exploit actually looks like. This guide breaks down CVE analysis step by step — fingerprinting targets, reproducing vulnerabilities, and mapping the real blast radius with real commands and tool output.
Pass-the-Hash and Pass-the-Ticket attacks let adversaries move through Active Directory without ever cracking a password. This post walks through real Mimikatz and Impacket output, explains what it means, and shows exactly what defenders should do first.
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 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.
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 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.
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 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.
BloodHound maps Active Directory attack paths that attackers exploit and defenders miss. This guide walks through real SharpHound collection, Cypher queries, and ACL remediation with actual command output at every step.
Attackers used a single cron entry to maintain access to a fintech build server for 47 days. Learn how to find malicious cron jobs across all seven persistence locations on Linux, and lock down cron before the next attacker does the same to you.
AI copilots are running with secrets in their environment and no injection defenses — a combination attackers are actively exploiting. Here’s how to enumerate your agent’s real access, test for prompt injection with Garak, and enforce runtime tool policies before something goes wrong.
