I am excited to share with you today a significant discovery I made regarding a new technique for bypassing OTP (One-Time Password) systems. This discovery has the potential to improve our understanding of security vulnerabilities and enhance the overall protection of sensitive information.
During my recent research efforts in the field of cybersecurity, I stumbled upon a previously unidentified vulnerability that allows for the bypassing of OTP mechanisms. OTPs are widely used as an additional layer of security in various applications, including online banking, two-factor authentication (2FA), and account recovery processes.
By carefully analyzing the inner workings of OTP systems, I have developed a novel approach that exposes a potential weakness in their implementation. While I cannot delve into the specific technical details for security reasons, I can assure you that this vulnerability has been thoroughly tested and validated.
Importance and Impact:
The significance of this discovery lies in its potential to assist developers, security experts, and organizations in fortifying their systems against such bypass techniques. By highlighting this vulnerability, I aim to raise awareness about the challenges faced by OTP-based security systems and encourage the implementation of stronger security measures.
POC:- 1. Enter mobile no.
2. Submit the request and you can see the OTP field,
3. Now click Resend OTP and capture the request.
4. Now you can see the pic in the request, Now drop the request and enter the pin in the OTP field.
5. After submitting the request you can see the user dashboard.
OTP bypass how to prevent (recommendation):
- Do not share OTP in response.
- Do not send OTP in HTTP response.
- OTP should be unique for each request and should be invalidated after one use.
- Implement rate-limiting mechanisms to prevent brute-force attacks.
- Implement time-based OTPs that expire after a short duration.
