Step 1: you'll need a private setup to become a digital "ghost". This includes running Hardened Gentoo over Sway (Wayland) on an Olinuxino board with wiped ARM firmware, w/ i/o plug-ins for the Modos paper display, Keyboardio keyboard and/or Ploopy mouse kit (or FPGA mouse if your keyboard doesn't already have a scroller). Then take another Olinuxino board w/ wiped firmware w/ ath9k PCIe w/ plug-ins and serial ports, which you hook-up to your default ISP router to run IP over DHCP ethernet connection for all connections on your SBC workstation. Then install nftables, firejail, kvm/qemu, auditd, fail2ban, pyshark, your web browser being either GNU Ice Cat w/ LibreJS or ELinks (a terminal browser used for scouring geocities and wiby.me type sites) or GNUNet and a custom SOCKS5 proxy using X25519, Poly1305, ChaCha20 and Kyber for post-quantum protection (optionally you can use gnunet-vpn), and practice OPSEC w/ passwords, including a USB flash drive (open hardware only; use an Ovrdrive USB flash drive) w/ KeePassXC password (or BitWarden or masterpassword.app), using xkpasswd.net for generating passwords for self-hosted emails (using VPS; please do not use your own homeserver for this).
Add an additional MilkV SBC and flash Zeek (Bro) or Suricata on it for network traffic analysis that's automated and shuts out any suspicious traffic. Then optionally feed logs into an LLM for analysis. And as a coup de grace, give it USBguard to prevent evil maid attacks w/ panic mode that encrypts all files.
Use Jami or GNUNet CADET for VoIP calls.
Step 2: now all you've gotta do is punch in your questions to an LLM (like llama.cpp) and install files through Linux terminal command line interface. From there, you can install Wifi password and firewall cracking tools or write them!
Step 3: ???
Step 4: PROFIT!
