CYBER &
SIGNAL
Intelligence
MASTERCLASS — Hosted by 44jackk
Learn to see, understand, and defend the invisible signals around you — off-grid, online, and at home.
Every device around you is transmitting. Most people never think about what that means until it's too late.
44jackk, researcher at Espionic Technologies, breaks down the real-world intersection of signal intelligence, cyber operations, and everyday security. No fluff. No theory overload. Just practical knowledge you can apply immediately.
Join the mailing list to be the first to know when sessions open. Topics span RF intelligence, cybersecurity, off-grid communications, and electronic engineering.
Signals & Exposure
The signals your devices broadcast without your knowledge — and what they reveal to anyone listening with the right hardware.
The Infrastructure Problem
Why switching phones, deleting apps, or using encrypted messengers gives you a false sense of security at the hardware level.
Off-Grid Communications
How to communicate without cell towers, SIM cards, or internet dependency — and the scenarios where this becomes critical.
Live Demonstrations
Real tools. Real hardware. You'll see exactly what's possible against everyday wireless infrastructure — demonstrated live, in real time.
Signal Monitoring
How to read and interpret what's happening in your own wireless environment — and what that data tells you about your exposure.
Practical Mitigations
Once you've seen what's possible, we cover how to actually defend against it — at home, on your network, and on your devices.
Kali Linux
The industry-standard offensive security operating system — used live during demonstrations to show real-world capability.
HackRF One
Software-defined radio hardware capable of transmitting and receiving across a wide frequency range. Used for live RF analysis.
Wireshark
Live packet capture and network traffic analysis — you'll see exactly what's moving across wireless networks in real time.
Aircrack-ng Suite
Industry-standard wireless auditing toolkit — used to demonstrate what an attacker sees when targeting WiFi infrastructure.
RTL-SDR
Low-cost software-defined radio for passive signal monitoring. Used to show what's broadcasting around you at any given moment.
