Penetration Testing

This article is written from 14+ years of offensive security practice. Some links are affiliate links that help keep this site running — I only recommend tools and services I’d use myself. Kali Linux comes loaded with over 600 security tools. If you’re new to penetration testing, that’s not empowering — that’s paralyzing. Here’s the honest truth: working pentesters don’t use most of what’s installed. They use a tight core of tools extremely well, and add specialized ones when a specific engagement calls for it. The practitioners who get hired aren’t the ones who can name every tool — they’re the ones who can actually use ten of them. ...

Metasploit is the exploitation framework everyone knows and half the people actually understand. This cheat sheet covers everything from first-time msfconsole navigation to post-exploitation pivoting — organized by how you actually use it on an engagement, not alphabetically by command. Updated for 2026. Bookmark it. Starting Metasploit # Start msfconsole msfconsole # Start with quiet mode (skip banner) msfconsole -q # Start with a resource script msfconsole -r setup.rc # Start with a specific database msfconsole -y /path/to/database.yml # Update Metasploit msfupdate Database Setup Metasploit’s database stores hosts, services, credentials, and loot. Worth setting up. ...

There’s a specific moment in a red teamer’s career when OSCP stops feeling like the ceiling and starts feeling like the floor. You’ve got your shells. You can pivot. You understand the methodology. But real engagements don’t look like OSCP machines. They look like hardened Active Directory environments with EDR, segmented networks, and defenders who are actually watching. That’s exactly the gap the CRTO fills. The Certified Red Team Operator from Zero-Point Security is the most practical red team certification I’ve seen in the mid-level space. It’s taught by Daniel Duggan (known in the community as RastaMouse), covers Cobalt Strike end-to-end, and teaches you how to operate inside a defended environment — not just pop boxes. ...

You don’t memorize Nmap. Nobody does. You keep a cheat sheet, you use it constantly, and eventually the important stuff sticks. This is that cheat sheet — updated for 2026, organized by what you actually do on engagements, not alphabetically by flag name. Covers everything from basic discovery to NSE scripting to firewall evasion. If it’s not here, you probably don’t need it in the field. Target Specification These go at the end of any Nmap command. Mix and match as needed. ...

Every week someone asks me what certification to start with. Not what to get after two years of HTB and home lab practice. Not what comes after OSCP. The first one — the one for people who know they want to break into offensive security but don’t know where to start. My answer in 2026 is still the eJPT. Not because it’s prestigious. Not because it’ll make a hiring manager’s eyes light up. Because it does something more important than that: it teaches you what a penetration test actually feels like, before you’re in over your head. ...

If you’ve spent any time in offensive security communities, you’ve seen the debate: build a home lab vs spin up a VPS and call it a day. Both camps have loud advocates, and both camps are partially right. I’ve run dedicated home labs for years, and I’ve also done engagements and personal research entirely on cloud infrastructure. Neither is universally better. The right answer depends on what you’re trying to learn, your budget, your living situation, and — critically — your threat model for legal exposure. ...

This list comes from 14+ years in offensive security — OSCP, CISSP, hundreds of engagements. Affiliate links help keep this site running. Every book here I’ve personally read and would hand to someone joining my team. There are two kinds of “best hacking books” lists. The first kind is a roundup of books someone found on Amazon and ranked by star rating. The second kind is a list from someone who’s actually used these resources on real engagements, in real prep for real certifications, with real clients waiting on the other end. ...

Written by a certified security professional (CISSP, OSCP) with 14+ years in offensive security and security leadership. Affiliate links help keep this site running — we only recommend resources we’d use ourselves. Every month there’s a new “best hacking books” list that looks like it was written by someone who Googled “cybersecurity books” for 20 minutes. This isn’t that. This is the list I’d hand to someone joining my red team. Books I’ve read cover to cover. Tools I reach for on real engagements. Gear that’s been through lab abuse and field use. If it’s here, it earns its place. ...

The OSCP used to be the only certification that mattered for penetration testers. Then TCM Security released the PNPT and changed the conversation. In 2026, the PNPT has become one of the most respected entry-to-mid-level certifications in offensive security — not because of brand recognition, but because of what the exam actually tests. This is a full review of whether it belongs in your certification roadmap. What Is the PNPT? The Practical Network Penetration Tester (PNPT) is a certification from TCM Security , created by Heath Adams (The Cyber Mentor). It’s a fully practical exam — no multiple choice, no CTF flags, no memorization. ...

Claude just found 500 zero-days in production software. Kali Linux now has a native AI integration. Every security vendor is slapping “AI-powered” on their marketing page. And you’re sitting there thinking: okay, but where do I actually start? This guide is for you — the practicing pentester who knows their craft, understands the methodology, but hasn’t figured out how to meaningfully integrate AI into real engagements. We’ll cover the full kill chain, with concrete prompts, real tools, and honest assessments of where AI helps versus where it still fails. ...
