Using a web proxy tool like , the tester intercepts the HTTP request that is sent when a user submits their OTP for verification. This request, which includes the OTP value, is then sent to an advanced extension like Turbo Intruder .
: Testing if multiple rapid requests can "race" the system before a lockout is triggered. 3. Attack Vectors and Risks
: A standard for fuzzing, containing all 1 million permutations. Bug-Bounty-Wordlists (GitHub) : A similar list optimized for bug bounty hunters. Crunch Wordlist (GitHub) : Often used by tools like John the Ripper or Hashcat. How to Generate Your Own (Python) 6 digit otp wordlist
The scenario described above is only possible because of a single, catastrophic security failure: . The entire foundation of a 6-digit OTP's security rests on the fact that a server will reject repeated, rapid attempts. The math makes this clear. A 6-digit OTP has 1,000,000 possible values. If a system limits attempts to, say, 5 per minute, it would take over 138 days of continuous testing to exhaust all possibilities.
A one-time password (OTP) is an automatically generated numeric or alphanumeric string that authenticates a user for a single transaction or login session. Six-digit OTPs are the industry standard because they strike a balance between security and usability: Using a web proxy tool like , the
Hashcat, the popular password cracking tool, can generate candidate OTPs on the fly without storing huge files:
OTPs are designed to be "one-time" and expire quickly (often within 30–60 seconds), making long wordlists less effective for live attacks. Crunch Wordlist (GitHub) : Often used by tools
Before launching any attack, the tester must understand the battlefield. They determine the OTP length (6 digits), the validity period (e.g., 30 seconds to 5 minutes), and most importantly, if there are any wrong attempt limits. Are you locked out after 3 wrong tries? Or can you attempt 15 times without a block? The answers to these questions dictate the entire attack strategy.
