Description

I have designed my own Captcha. If you solve it fast enough I'll give you my flag. Can you help me test it?

Write-up

• Our objective was to solve 100 captchas within a time limit of 2 minutes.
• Since the captchas appeared to be simple, we decided to develop a script that utilizes pytesseract for Optical Character Recognition (OCR) and Selenium for web automation. The script would automatically submit each solved captcha.
• You can find the script we created for solving the captchas here.
