9 Original Cybersecurity Plugins I Developed for Omarchy Linux and 4 Official Themes

Summary: Nine security and developer plugins I wrote for Omarchy are listed with short descriptions and their repositories. The second part of the article introduces four desktop themes: the Türkiye theme using 21 historical sites in Türkiye, the Steam Machine theme, and the Ankara and İstanbul themes.

To take the desktop experience to the next level in the Linux and open source world, I developed and released as open source 9 original cybersecurity and developer plugins and 4 official desktop themes specifically for the Omarchy ecosystem, a modern Arch Linux desktop environment.

All developed plugins have been submitted to the official Omarchy Plugin Marketplace (plugins.omarchy.org) directory and are completely free and open source under the MIT license.

1. Cybersecurity, OPSEC and System Shield Plugins

BadUSB Shield (Anti-BadUSB and Hardware Watchdog)

Monitors USB devices plugged into the system. It instantly detects devices that look like an innocent USB drive but act like a keyboard in the background to inject malicious code (BadUSB / Rubber Ducky attacks).

GitHub Repository: ozdil/omarchy-badusb-shield

Auth Watch (SSH and Sudo Unauthorized Login Watchdog)

Filters failed sudo password attempts on the system and incoming SSH intrusion / brute-force attempts in real time and gives instant alerts in the top bar.

GitHub Repository: ozdil/omarchy-auth-watch

Tripwire Vault (Canary File and Ransomware Trap)

Places cryptographic canary (honey-token) files in critical system directories. The moment malware or ransomware touches the files, it raises an alarm on the desktop.

GitHub Repository: ozdil/omarchy-tripwire-vault

DNS Leak Guard (Live DNS Leak and DoT Shield)

Checks whether your DNS queries leak to the ISP in plain text. It protects your internet privacy by verifying DNS-over-TLS (DoT) encryption.

GitHub Repository: ozdil/omarchy-dns-leak-guard

Ghost MAC (Wi-Fi Anonymity and Random MAC Mask)

On public Wi-Fi networks (municipal, café, airport), it masks your physical hardware MAC address and machine name with a random fake identity to prevent physical tracking.

GitHub Repository: ozdil/omarchy-ghost-mac

OpSec Cleaner (Digital Fingerprint and EXIF Sanitizer)

A digital hygiene tool that zeroes out GPS location coordinates, camera serial number, capture timestamp and user traces before uploading a photo to social media.

GitHub Repository: ozdil/omarchy-opsec-cleaner

CVE Radar (Arch Linux Package and Binary Security Auditor)

Scans 1,100+ packages on the system and SUID-privileged system binaries using the official Arch Linux Security Tracker API and reports vulnerabilities instantly.

GitHub Repository: ozdil/omarchy-cve-radar

Cyber Sentinel (Live Network Radar and Port Watchdog)

Monitors all active network sockets open to the outside world in real time. It offers the ability to terminate the process with a single click on connections to suspicious and non-standard ports.

GitHub Repository: ozdil/omarchy-cyber-sentinel

2. Developer and Workspace Plugins

Git Radar (Developer Pulse and Commit Heatmap)

Scans all your local repositories. It visualizes your daily commit count, repositories with uncommitted changes and a GitHub-style commit heatmap of the last 7 days directly in the bar.

GitHub Repository: ozdil/omarchy-git-radar

3. Official Omarchy Desktop Themes

Türkiye Theme (21 Iconic Sites): Brings together Cappadocia, Göbeklitepe, Pamukkale, Nemrut, Sümela and 21 historical sites in Türkiye with 8K vector wallpapers and an OLED turquoise color palette. (GitHub)
Steam Machine Theme: A dark cyberpunk gaming theme carrying the spirit of Valve, Half-Life and retro arcade. (GitHub)
Ankara and İstanbul Themes: Themes that bring the ancient aesthetics of the capital and the Bosphorus to the modern Linux desktop. (GitHub Ankara | GitHub İstanbul)

All projects are shared as open source under the MIT license.

My take

Plugins can be installed individually: each tool lives in a separate repository and serves a separate need.
Themes are part of the ecosystem too: alongside the security tools, there are themes that highlight local venues.
Everything is open source: the plugins and themes were shared under the MIT license.
