Naomi Brockwell Joins JHT All-Stars! New Free Upskill Challenge: Create your own encrypted USB drives. justhacking.com/uc/uc-encrypte… Storing sensitive files on a normal USB drive is like writing your diary on a sticky note and leaving it in a taxi. If someone gets the drive, they get the files. No hacking required! Naomi shows three ways to create encrypted USB drives: The Apricorn Aegis Secure Key, the Kingston IronKey Vault Privacy 50C, and VeraCrypt. Find out how they compare, which best fits your threat model, and step-by-step setup tutorials for each. #cybersecurity #hacking #privacy #encryption @naomibrockwell

🚨 Workshop Spotlight # 5👉 "Instant API Hacker" by Corey J. Ball (@hAPI_hacker), author of "Hacking APIs" and founder of APIsec University (@apisecu) & hAPI Labs 📝 Description "Instant API Hacker" demonstrates how quickly someone can learn to identify and exploit API vulnerabilities. You'll witness the exploitation of critical vulnerabilities from the OWASP API Security Top 10, including broken authentication, authorization flaws (BOLA), and excessive data exposure. Through live demos using the "One Request to Rule Them All," you'll see firsthand how APIs can be compromised, and gain actionable insights you can apply immediately. The session walks through finding APIs, analyzing endpoints in Postman, going deep with Burp Suite, and exploiting the most common vulnerabilities. You leave with free resources for continued learning, including vulnerable labs and APIsec University courses. Beginner-friendly. By the end, you're an API hacker. 🎟️ Only at ContinuumCon 2026 Work through it live, or revisit the lab on your own time. Own it forever. The workshop doesn't end when the conference does. Got your ticket yet? 👉 continuumcon.com Hosted by @_JohnHammond, @JustHackingHQ, @AnthonyBendas, and @Level_Effect!

🚨 Workshop Spotlight 👉 "Prompt Injection Fundamentals & Hack-Along" by Eva Benn & Andrew Bellini (@d1gitalandrew) 📝 Description Prompt injection continues to be # 1 on the OWASP Top 10 for LLM Applications for the second edition running, and there's a reason it isn't moving. LLMs read instructions, data, and policy through the same channel. The attack surface is the entire space of human language, with infinite ways to phrase an input and infinite ways the model can respond. A single successful prompt injection can bypass every other security control you put in place, even if you've done everything else right. Model makers like OpenAI, Anthropic, and Google continue to invest in instruction hierarchy training and built-in safety controls, but models still can't reliably tell the difference between what the app builder told it to do and what an attacker hid inside a document, an email, a webpage, or a tool response. And the people building AI apps aren't just engineers anymore... This session is a practical, beginner-friendly walkthrough of prompt injection fundamentals. It's a solid on-ramp if you want to get into AI pentesting, or if you're building with AI and want to know what you're actually up against. 🎟️ Only at ContinuumCon 2026 - June 12-14 Work through it live, or revisit the lab on your own time. Own it forever. The workshop doesn't end when the conference does. Got your ticket yet? 👉 continuumcon.com Hosted by @_JohnHammond, @JustHackingHQ, @AnthonyBendas , and @Level_Effect !

Many aspiring pentesters never start because web app security feels too advanced. Mike Lisi explains why hands-on exposure matters more than worrying about prerequisites early on. That’s what Crosswind Systems is built for. A free place to practice web app hacking concepts and start building real experience. 🛠️ JHT’s gift to the community.

One of the biggest gaps in cybersecurity education right now is practical pentesting experience. Mike Lisi explains why theory alone isn’t enough and why more practitioners need to help bridge the gap with real-world skills, mentorship, and hands-on exposure. That’s how junior pentesters become job-ready faster. 🔗 Start learning: justhacking.com/course/web-app…

A junior pentester went from beginner to finding real vulnerabilities in a few months. According to Mike Lisi, it came down to: • Real-world tool output • Context • Repetition That’s what actually builds skill. 🔗Start learning: justhacking.com/course/web-app…

The RF world is insane. Researchers recovered AES-128 keys from a Bluetooth chip by listening to its own antenna from 10 meters away. Crypto-engine switching noise couples into the RF chain, rides the 2.4 GHz carrier, and leaks out as radio.

Much of the effort in purple teaming happens before execution. Reviewing threat intel, mapping TTPs, and planning what to emulate can take significant time. @Antonlovesdnb shows how AI can assist with that process so teams can spend more time on testing and communicating results. 👉️ Learn more: justhacking.com/course/ai-cybe… 20% launch discount ends April 30 at Midnight ET⏳️
