HawkOpsec

One-tap Linux OPSEC hardening & anonymity toolkit

HawkOpsec turns a pile of manual privacy commands into security modes you apply with one tap. Pick a mode — the tool starts Tor, configures DNS, randomizes your identity and hardens the kernel for you. Hit RESET and every change is rolled back from snapshots to your original state.

The GUI never runs as root; privileged actions go through a small helper via polkit/pkexec. Every change is snapshotted before it is applied, so nothing is one-way.

Security modes

Each mode resets to baseline first, then applies a full profile — switching is always clean.

Architectural Structure

Features

• Network — Tor transparent proxy (all TCP + DNS via Tor, kill-switch, IPv6 block, stream isolation), DNS-over-TLS (Quad9 / Cloudflare / Mullvad), default-deny firewall, IPv6 disable.
• Identity — per-interface MAC randomization, persistent MAC (NetworkManager), random hostname, machine-id spoofing, UTC timezone.
• Hardening — kernel/sysctl hardening, disable crash reporting/coredumps, journald to RAM, disable Bluetooth, disable swap, USB lockdown (BadUSB), RAM wipe on shutdown.
• Traces — clean shell history / recent files / thumbnails / trash, vacuum journald & coredumps, strip EXIF metadata (mat2/exiftool), secure-delete (shred).
• Extras — one-click anonymous browser (Tor Browser / Firejail), Firefox hardening (WebRTC off, resistFingerprinting), live exit-IP check, Activity log of every change, RESET and PANIC.
• Bilingual UI — switch English / Türkçe from the top-right; choice is remembered.

Install

Dependencies

# Arch
sudo pacman -S --needed python-pyqt6 tor nftables polkit iproute2 rfkill systemd-resolvconf
# Debian / Ubuntu / Kali / Mint
sudo apt install -y python3-pyqt6 tor nftables policykit-1 iproute2 rfkill systemd-resolved
# optional extras: mat2 (or exiftool), secure-delete, firejail, torbrowser-launcher

Run from source (quickest)

python3 run.py                 # just run it
sudo ./packaging/install.sh    # or install: menu entry + launcher + polkit + helper

Compile to a standalone binary (Nuitka)

sudo apt install -y patchelf                 # or: sudo pacman -S patchelf
./packaging/build.sh                         # -> build/run.dist/hawkopsec
sudo ./packaging/install-compiled.sh

Then launch HawkOpsec from your application menu, or run hawkopsec.

Uninstall

Click UNINSTALL in the app (or HawkOpsec Uninstall in the menu), or:

sudo ./packaging/uninstall.sh

It reverts every system change, removes all files and menu icons, and refreshes the desktop cache.

Security note

HawkOpsec hardens the network and system layers. It does not make a normal browser fingerprint-resistant — for real anonymous browsing use the built-in Tor Browser launcher, avoid logging into personal accounts while anonymous, and remember that browser fingerprinting, WebRTC and behavioural patterns are out of scope for a system tool. You are hardening your own machine.
