RomHack Training

Come to Roma 🇮🇹 in September and attend the only in-person public training session I'll give in 2026! 👨‍🏫

And if you like camping with other hackers (as I do), stay over the weekend for the 3-day long RomHack Camp 🏕️

Last week, I had the opportunity to attend the 4-day Mastering Burp Suite Pro training by 🛠️ Nicolas Gregoire, and it exceeded my expectations by far.

This wasn’t just another slide-driven course. Nicolas took the time to answer every question in depth and provided plenty of hands-on labs, allowing us to immediately apply what had just been explained.

Even though I’ve been working with Burp for nearly five years, I still picked up a surprising number of new techniques and practical tricks, including ways to streamline otherwise time-consuming workflows such as managing CSRF tokens both with and without session handling rules.

What I especially appreciated were the little side explorations (driven by our requests) into methodologies for leveraging features and extensions to remain stealthy or bypass WAFs. This is something that’s particularly relevant (and often underestimated) when exploiting external or internal web applications during advanced Red Team engagements.

I’m genuinely looking forward to applying this newly gained knowledge in upcoming projects, and I can wholeheartedly recommend this training to any (web) pentester who wants to level up their Burp skills.

Big thanks to Nicolas for an excellent and highly practical course!

Thanks to everyone who nominated & voted in the top ten! The panel of @irsdl.bsky.social , @agarri.fr , @liveoverflow.bsky.social and myself are hard at work reviewing the 15 finalists... we're hoping to announce the winners next week!

In case you didn't vote yet (2 days left!), let me tell you that your participation is critical 🗳️

Indeed, the panel (that I'm part of) will only process the top X results and it may contain some sh*tty entries (because of ballot stuffing 🥴)

So please do your part! 🙏
