Cryptography CTF challenges recycle the same attack surfaces — Caesar shifts, XOR key reuse, and weak RSA — across nearly every competition. Learn to recognize them fast with real Python commands, tool output, and a clear path from ciphertext to flag.
DNS beaconing, C2 check-ins, and payload delivery all leave traces in packet captures. This guide shows you how to use Wireshark and tshark to find them — with real display filters, output examples, and concrete next steps for every finding.
Device code phishing, managed identity abuse, and cross-tenant B2B pivoting are the defining Entra ID attack paths in 2026. This post walks through each technique with real commands so defenders know exactly what to look for.
CVE-2024-1086 showed that a single kernel bug can hand attackers full root — fast. Before you can defend or research Linux kernel vulnerabilities, you need to map exactly what the kernel exposes to user-space. This post walks through real commands to enumerate syscall interfaces, eBPF exposure, and io_uring attack surface on a live system.
A $25 million deepfake wire fraud in 2025 exposed how few enterprises have any detection layer between a synthetic video call and a bank transfer. This guide walks through voice similarity scoring, SIEM correlation queries, and four prevention controls you can implement this week.
Slow enumeration beats fast fuzzing every time in binary exploitation CTF challenges. This guide walks from checksec recon to a working pwntools exploit — with real commands and real output at every step.
Metasploit is the exploitation framework behind real-world penetration tests — not just a beginner sandbox. Walk through a complete workflow: finding modules, landing a Meterpreter session, and escalating privileges with post-exploitation modules.
Analysts who loaded AsyncRAT payloads into Ghidra found the C2 address and persistence logic in under 20 minutes — without running a single line of malware. This beginner guide walks you through real decompiler output, from unpacking a UPX binary to identifying beacon functions and registry persistence.
A Fortune 500 breach in early 2026 started with a single exposed .env file and a weak JWT secret. This guide walks through the exact recon, exploitation, and chaining techniques modern pentesters use — complete with real commands and tool output.
Kerberoasting lets any domain user crack service account passwords offline — no special privileges needed. Walk through the full attack chain from SPN enumeration to Domain Admin with real commands and output, then lock it down before someone else runs these same steps against your environment.
SSH misconfigurations, unmonitored privilege escalation, and permissive kernel defaults put Linux servers at risk every day. This 2026 checklist gives you real commands and actual output to lock them down — starting in the next five minutes.
Prompt injection is the SQL injection of AI apps — and most teams are shipping it unmitigated. Walk through two real attack scenarios with tool output, understand what attackers do with a successful injection, and learn the layered defenses that actually hold.
