Easebuzz Auto Captcha Solver Chrome Extension

This Chrome extension automatically solves the image–selection captcha that appears on the Easebuzz Merchant Dashboard.

⚠️ Security Notice

This extension demonstrates that Easebuzz's current captcha implementation is fundamentally flawed. The image-selection captcha can be trivially bypassed using vision AI models like OpenAI's GPT-4 Vision. There is no point in using such captchas as they provide zero security against automated attacks while creating unnecessary friction for legitimate users.

Message to Easebuzz Engineers

If any Easebuzz engineer is reading this: Please remove this ineffective captcha and either make the user flow easier; without captcha barriers or use a better captcha service.

How it works

1. Runs only on https://easebuzz.in/merchant/dashboard.
2. Clicks the captcha START button inside #captcha-container.
3. Waits for the 3×3 image grid (rendered as a <canvas>).
4. Captures the canvas as a base-64 image, reads the instruction text (e.g. Choose all the curtains).
5. Sends both to OpenAI Vision to receive an array of the 5 grid indices (1–9) that match the instruction.
6. Automatically clicks the matched buttons and submits the form to solve the captcha.

Installation / Usage

1. Clone or download this folder.
2. In Chrome, open chrome://extensions, enable Developer mode, click Load unpacked and select this directory.
3. Click the extension icon → Options to store your OpenAI API key.
4. Visit https://easebuzz.in/merchant/dashboard and trigger the captcha.

Security notes

Your OpenAI key is stored locally via chrome.storage.local and is never injected into page context.
