Consider these techniques for bypassing captchas during penetration testing or bug bounty.

Read the detailed blog on :

Method 1: Reuse Previous Captcha

This technique involves using a captcha code that you’ve seen or solved before, assuming that the same code will work again multiple times.

Method 2: Submit Empty Captcha #

Trying to bypass the captcha by leaving the captcha field empty when submitting a form.

Method 3: Alter Data Format

Changing the format in which data is sent to the server, such as converting it to JSON or plain text, in the hope that the captcha won’t be validated.

Method 4: Change Request Method

Modify the way you send requests to the server by switching between different HTTP request methods like GET, POST, or PUT.

Method 5: Manipulate Headers

Using custom headers like X-Forwarded-For, X-Remote-IP, X-Original-IP, X-Remote-Addr, etc., to make it appear as though the requests are coming from different IP addresses, thereby avoiding captcha validation.

Method 6: Inspect Parameters #

Always thoroughly examine the entire request (body, headers, or uri part) and understand the purpose of each parameter. By changing certain parameter values, you might find a way to bypass the captcha.

Method 7: Automate with Tools

Using automation tools like Selenium or OCR (Optical Character Recognition) software to automatically identify and solve captchas.

Method 8: Human-Based Captcha Solving Services #

Instead of automated methods, you can use human-based captcha-solving services where real individuals solve captchas for you in exchange for a fee.
