Hi! I'm Don.

The winter solstice is our annual reminder that just when it seems the darkness is too much, the light will return. Regardless of season, may your hearts forever stay warm. ♥️

SF here we come! Join us in the @IoTvillage at both @BSidesSF & @OneRSAC. Try our 2 new hands-on mini-workshops, get some swag and be sure to say hi to John & Don. Forget the noise. Get to JustHacking.com! Both also available free rn at JHT. 😁

Day 4 of #ClaudeForBlueTeam We'll keep with the Obsidian & ATT&CK theme. Yesterday we loaded all of ATT&CK into Obsidian. But what if you want to get more surgical ? You can prompt Claude to make you a slash command: /attack-note. This command takes in an ATT&CK ID and uses the Obsidian CLI to build a note for you using the ATT&CK JSON data. Token efficient & flexible!

There’s an old security saying: If an attacker has physical access, it’s game over. At the hardware level, protections are limited. Dumping RAM and inspecting memory becomes very real. This is exactly what we explore in Hardware Hacking 101. Shoutout @_t1v0_ for the hardware platform 👏 justhacking.com/course/hardwar… 💥 20% Launch Discount ends March 31.

It's 3:14 on 3-14. Happy #PiDay!

Feed the mind. Enjoy #piday!

We built a hardware target to teach exploitation. @_t1v0_ designed the PCB. Then built the bootloader + OS. We intentionally included vulnerabilities. It’s meant to be broken! Hardware Hacking 101 👉️ justhacking.com/course/hardwar… 💥 20% Launch Discount ends March 31

This hits hard

This is amazing, LLMs can sometimes hack sites just because it's the most direct way to answer a user's question

Level up your IR skills by mastering Linux data analysis. Parse artifacts. Pull logs from the host. Apply it in real forensic workflows. That’s real defensive depth. Appreciate @Antonlovesdnb’s perspective. Learn more: justhacking.com/course/constru… #CyberSecurity #DFIR #LinuxSecurity #BlueTeam

Do we live in a computer simulation? So far this question has been pursued mostly by philosophers because it was just too vague to make scientific sense of it. But this situation has changed now. youtube.com/watch?v=UbInSC…

Learn Basics of Hardware Hacking! 🛠️ justhacking.com/course/hardwar… Only $280 for Trevor Stevado's hands-on course with included custom kit. 20% Launch Discount ends March 31. This is Hardware Hacking 101! Learn from the best... Trevor AKA @_t1v0_ is a DEF CON Black Badge Winner, Co-Founder of the Embedded Systems Village, almost 20-year professional turned... homebrew supply store owner?!?! Passion project and pentesting. He's amazing! With included custom kit, hours of video, step-by-step instructions, hands-on labs, instructor walk-throughs and quizzes, this intro course is designed to give you the foundational skills needed to analyze, interact with, and exploit embedded systems at the hardware level. Whether you’re a penetration tester looking to expand into IoT security, a developer wanting to understand how attackers target your devices, or simply curious about what’s happening beneath the surface of the electronics around you, this course will provide you with practical, hands-on experience. The skills you’ll learn here are directly applicable to real-world job tasks. The same techniques used in this course have been used to find vulnerabilities in everything from consumer routers and smart home devices to industrial control systems and automotive electronics. HH101 is built around hands-on labs. To complete them with as few stumbling blocks as possible, we include a hardware kit made exclusively for this course: - Custom T113-S3 Target Board - Custom FT2232H Interface Board - Jumper Wires - Custom Linux VM **And the kit is yours to keep!** Any IoT devices laying around your home? Use the kit to continue honing your craft long after the course is done! Ethically, of course. Forget the noise.

Cookie theft isn’t stealthy. A stolen session creates host telemetry, network signal, and cloud session anomalies. The advantage comes from correlating those layers instead of treating them separately. Appreciate @Antonlovesdnb’s perspective on this.

New Free Upskill Challenge! justhacking.com/uc/uc-nessus/ "Pentesting for the Masses" series on common hacking tools used on the job. This time... Nessus. This Free UC by @G1zm0_infosec is part of JHT’s new series on Pentesting for the Masses, where we will explore numerous tools used throughout an actual engagement. This UC offers a ground-up introduction to vulnerability assessment with Nessus. You’ll learn not just what Nessus does, but why vulnerability scanning matters, how misconfigurations and outdated software create measurable risk, how authenticated vs. unauthenticated scans change results, and how vulnerability data translates into actionable remediation. We’ll unpack Nessus’ core functionality and its major components such as scan configuration, plugin architecture, credentialed scanning, severity classification, and reporting workflows. Rather than simply running a scan and reviewing a list of findings, we will implement a practical workflow you can immediately apply: scope definition → scan configuration → credential selection → vulnerability analysis → validation and prioritization. Along the way, you’ll get examples, interpretation strategies, alternatives to Nessus and practical insights drawn from real-world assessment experience. You might even take a peak tesla dot com :-O #nessus #pentest #pentesting #penetrationtest #va #vulnerability #assessment #vulnerabilityassessment #hacking #ethicalhacking #methodology #justhacking #justhackingtraining #tenable #scanning --- Just Hacking Training is a platform providing "Focused Technical Training for All Levels" in 80+ affordable, hands-on options in 4 categories: Courses, Free Upskill Challenges, Hack-Alongs and CTFs.
