Understanding OTP and CAPTCHA Bypass Techniques

Introduction

In the digital age, securing online transactions and protecting user accounts from unauthorized access have become paramount concerns. Two of the most widely employed security mechanisms are One-Time Passwords (OTPs) and CAPTCHAs. These techniques are designed to authenticate legitimate users while preventing automated attacks and unauthorized access attempts. However, despite their effectiveness, cybercriminals continually seek new methods to bypass these defenses, posing significant challenges to online security.

In this comprehensive blog, we will dive deep into the mechanics of OTPs and CAPTCHAs, explore various bypass techniques, analyze the security challenges posed by these exploits, and discuss the evolving role of cybersecurity professionals in mitigating these risks.
