029 - Minimize not Militarize and Avoiding Surveillance with GrapheneOS

The Lockdown - Practical Privacy & Security

In this episode, I explore the difference between the military mindset and the more stealth approach of minimization in cybersecurity. I share the results from the Ghost in the Source Capture the Flag (CTF) challenge, revealing how the winners cracked the AES encryption using dictionary attacks, keyword harvesting and the cipher tool hidden in robots.txt. I discuss why the “assume breach” mentality just leaves the doors wide open, using examples from Kevin Mitnick’s 1981 Pacific Bell infiltration to modern ransomware groups like Scattered Spider who breached MGM and Marks & Spencer through social engineering.

I also cover practical tactics for using public Wi-Fi, data curation techniques, the invisible surveillance net including Stingray devices, and provide a deep dive into GrapheneOS covering user profiles, app sandboxing, network controls, sensor permissions, and the proper use of sandboxed Google Play services.
