Have you taken the new Securing AI Applications course yet? This course clocks in at just about 5 hours. It tackles the other side of the AI security coin: ensuring AI & LLM-based apps are secure from the start.

The course dives into the following concepts:

✔️ Secure Model Configuration
✔️ System prompt hardening
✔️ Input validation and prompt injection filtering
✔️ Using AI classifiers and AI as a judge moderator
✔️ Rate limiting and resource abuse prevention for AI endpoints
✔️ Output moderation and content filtering
✔️ PII Detection and sensitive data handling in AI responses

This course is one of our several AI-centric offerings.

Have you tried our CTF yet? 👀⌛

Operation Breadcrumbs is closing June 2nd, so you have a few days left to give it your best shot.

Try it this weekend! Let us know what you think (but don't spoil it for others!) https://hubs.la/Q04jhpXL0

Today we're celebrating Hamza Shah, a longstanding member of the TCM Security community, on landing his new pentesting role!

Hamza has put in serious work to get here, earning an impressive lineup of TCM Security certifications along the way:

🔹 PNPT (Practical Network Pe*******on Tester)
🔹 PWPA (Practical Web Pentest Associate)
🔹 PWPP (Practical Web Pentest Professional)
🔹 PHDA (Practical Help Desk Associate)

And he's not slowing down: the PAPA (Practical AI Pentest Associate) exam is up next on his horizon.

Beyond the certs, Hamza has been a genuinely loyal and helpful presence in our community, the kind of person who lifts others up as he climbs. That mindset, paired with his technical skills and persistence, is exactly what makes him such a great fit for this next chapter.

Hamza, we're rooting for you. Go show them what TCM-trained pentesters are made of! 💪

How do CTFs compare when it comes to realistically measuring your cybersecurity skills?

Andrew Prince sees it as a "give and take," and he explains why in this livestream clip, breaking down what they successfully do and where they can fall short.

Ultimately, CTFs can be very useful exercises - which is why we're running one right now! Operation Breadcrumbs will end June 2nd: https://hubs.la/Q04j6NR50

Operation Breadcrumb has officially begun. Will you be joining us?

For this CTF, you'll embark on a decoding adventure. Some web app, some OSINT, and some cryptography are all involved. And if you solve it, you'll be entered for the chance to win some considerable cash prizes.

If you solve it by the end date (June 2), tag us on social with your completion post - but don't give away the secrets until the CTF closes!

You've probably run into mkfifo reverse shells during CTFs. These command pipelines are a classic example of a reverse shell one-liner that can allow an attacker connect a compromised machine back to their own machine.

But have you ever wondered how they work? Andrew Prince dives into each component that makes up the shell n this quick tutorial. Watch along to see what goes on under the hood!

Remember: Our next CTF launches tomorrow! Until then, check out our blue team content in the TCM Security Academy: https://hubs.la/Q04hYTCR0
