When a Linux host is compromised, attackers leave traces in processes, auth logs, and persistence mechanisms. This guide walks through real forensic commands to find reverse shells, suspicious logins, and backdoors — fast.
AI-generated polymorphic malware rewrites its own code on every execution cycle, burning through binary hashes faster than signature databases can keep up. Learn how the mutation engine works, what it leaves behind in memory, and how to build detection rules that survive it.
ROT13, XOR, and weak RSA show up in nearly every CTF crypto track. Learn to identify the cipher, pick the right attack, and recover the flag fast — with real commands you can run right now.
GPU-accelerated cracking is how real-world password audits work. This guide walks through Hashcat setup, NTLM dictionary attacks, and rule-based cracking with real commands and output — everything you need to run a credential audit today.
Rootkits hide processes, files, and network connections by hooking the very syscalls your detection tools rely on. Learn how kernel-level hiding works and how to catch it using /proc cross-referencing and rkhunter — with real commands and output.
BloodHound maps Active Directory attack paths the same way attackers do — automatically and brutally efficiently. This guide walks through real SharpHound collection, Cypher queries, and a live GenericWrite-to-DA exploit chain with concrete remediation steps.
Cron is quiet, trusted, and runs as root — exactly why attackers use it to survive reimaging and incident response. Learn how to audit every cron location on a Linux host, detect malicious entries with auditd, and harden cron before an attacker gets the chance.
AI copilots can autocomplete secrets, execute injected instructions, and exfiltrate data — all without a single CVE. Here’s how to audit permissions, test for prompt injection, and add runtime monitoring before an attacker finds the gaps first.
Scattered Spider breached financial targets in 2025 without dropping a single file to disk. Learn how living-off-the-land attacks abuse PowerShell and WMI — with real commands and detection techniques you can run right now.
SSRF lets attackers turn your server into a proxy against internal systems — and the Capital One breach proved how far that pivot can go. This post walks through finding blind SSRF with interactsh, exploiting the AWS metadata service for live credentials, and bypassing common filters with real commands.
AMSI patching, PE stomping, and LOLBin loader chains are still bypassing Windows Defender in 2026 — including in nation-state campaigns. Walk through real commands, see what the output looks like, and learn exactly where to add detection coverage.
eBPF lets you hook directly into the Linux kernel to catch attacks — privilege escalation, reverse shells, suspicious syscalls — as they happen. Here is how to use bpftrace and BCC tools to see exactly what an attacker does the moment they do it.
