Reveal All Saved Wi-Fi Passwords on Linux in 1 Command!
🔍 QUICK DEMO: See every Wi-Fi profile and password stored on your Kali/Linux machine (demo uses a fake password — never expose real creds on camera).
Command shown:
sudo cat /etc/NetworkManager/system-connections/* | grep -i psk=
What this does:
This command reads NetworkManager connection files and filters lines that contain psk= — the Pre-Shared Key (plain-text Wi-Fi password) for each saved network profile. On systems using NetworkManager (Ubuntu, Kali, Debian-based distros), profile files live under /etc/NetworkManager/system-connections/. This reveals SSIDs and their saved PSKs.
Why this matters (short):
If someone gets root on your machine, they can read all saved Wi-Fi passwords instantly. This demo proves how sensitive local credentials are and why full-disk encryption, strong local security, and physical device protection matter.
✅ What I recommend (Security checklist)
Only run this on your own machine or an environment you control. Do NOT run this against other people’s devices.
Blur or redact any real passwords before publishing video/screenshots. Use a fake/demo profile for visuals.
Protect your device: enable full-disk encryption (LUKS), use strong user passwords, lock your screen when away.
Use a password manager for Wi-Fi passwords where possible.
Revoke access if you find unknown profiles or credentials.
📌 Troubleshooting & notes
If /etc/NetworkManager/system-connections/ doesn’t exist, your distro may use a different connection manager (wpa_supplicant, ConnMan, etc.).
You may need root privileges (sudo) to read these files.
On systems that use keyrings or GNOME Keyring, Wi-Fi passphrases may be stored there instead of plain files — those require different retrieval methods and stronger protections.
🔒 Ethics & Legal
Only inspect devices you own or have explicit permission to test. Unauthorized access, credential theft, or using extracted credentials unlawfully is illegal and unethical. This video is for security awareness, hardening, and learning only.
