Beyond excited to share that one of our most fun, interactive & knowledge-dense classes returns, this time at @BlackHatEvents Europe! 🎉

The talented @OSINTgeek & I will be teaching our "Fundamentals of Cyber Investigations & Human Intelligence" class on the 9-10th of December in London!
3 resources in 1 post:
Open AI has released a new report outlining the ways in which threat actors used their generative AI products to support their social engineering attack operations. They provide the case studies.

Very grateful for last week spent at X33fcon in Poland!
It started with 2 days full of #socialengineering & #OSINT training where I had the privilege to teach a class that was present, curious, and ready to try things out.
Big bonus: reconnecting with friends during the conference days afterwards😊

Agentic AI has opened new frontiers for adversaries looking to automate and scale attacks.

I wrote an article explaining what Agentic AI really is & how it can shape the future of the social engineering threat landscape.

There are a few things different this time around. 👇🏻

New class modules:
🔸️State-Sponsored social engineering schemes
🔸️Using AI for OSINT tasks (responsibly)
🔸️How attackers are using AI to supercharge their SE.

Hands-on, practical & realistic. See you at x33fcon in only 4 weeks! 😱🥳

If you are using #HUMINT techniques in your #CTI process, this is a talk worth watching.
Eliska & Julien do a great job in breaking down important concepts, risks, benefits & analytical aspects of using HUMINT tactics in a CTI workflow ⬇️

How can HUMINT be leveraged in Cyber Threat Intelligence?

The Dark Overlord investigation is an interesting report showcasing how HUMINT helps better understand threat actor activities, and even infiltrate their inner circles to uncover real identities.

Some notes 🧵

Snapshots from #BlackHatEurope!
Spent the week giving our 2-day training to a largely diverse class, strolling around London, celebrating a birthday (thanks to @osintgeek.de who is the best work buddy you can have), and attending the conference!
You can say it was a real FULL week.

Our 2-day training at #DeepSec is a wrap!
It was the first time I delivered a deep-dive focusing entirely on the #psychology interplaying in social engineering & HUMINT operations at a cybersecurity conference.

It is very energizing to have a class full of curious minds!
