You may click on any preview below to view it live. All templates are designed to:
- Be as simple and accurate as possible.
- Work on both mobile and desktop devices.
- Send a query param payload on form submit as
/login?username=example&password=example. - Be developed as HTML/SCSS but compiled to a single HTML file with inline CSS.
- Be compressed. Take note some hardware only supports displaying up to 20 KB templates at a time.
- Not use any JavaScript, vanilla HTML and CSS only. You may optionally add JS code yourself. See the Development section for more information.
All previews are hosted on raw.githack.com, a great CDN for source code!

Evil Portals are custom captive portal systems often used in penetration testing to demonstrate security risks. When connected to a rogue AP, users are directed to a fake login page, where attackers can attempt to capture credentials or inject payloads.
This repository provides:
- Realistic examples of AP-powered login systems ("Evil Portals").
- Configurable templates for use in controlled and authorized environments.
- Documentation on how these systems work (this README).
[ Index ]
The goal of this repository is to raise awareness about the vulnerabilities that attackers may exploit using "Evil Portals" — captive portals designed to mimic legitimate login systems on open access points (APs) or otherwise. By providing realistic examples of how these systems operate, this repository aims to:
- Educate network administrators and developers about potential risks.
- Demonstrate the importance of securing wireless networks against unauthorized access and data interception.
- Help organizations and individuals develop stronger defenses against phishing and other attacks facilitated by rogue APs.

- Clone this repository to your machine.
- Set up supported hardware:
- A Raspberry Pi Pico W or other supported hardware running Pico-Portal.
- A Flipper Zero Wi-Fi module or similar ESP32-based devices.
- A Wi-Fi Pineapple or similar device that supports captive portal testing.
- Use the provided templates from within the
/portalsfolder to simulate captive portals in a controlled environment. - Run, preview, and demonstrate with transparency the templates to educate users about the risks of rogue APs and phishing attacks.
