| Attack Type | Config Customization | |-------------|----------------------| | | Reuse stolen email:password dumps on banking/e-commerce sites. | | Card Cracking | Test stolen credit card numbers against low-value payment gateways. | | Token Brute-Force | Guess OTPs, referral codes, or gift card numbers. | | User Enumeration | Detect which emails are registered by analyzing "forgot password" responses. |
OpenBullet is a double-edged sword: a powerful automation framework for testers and a mass‑exploitation engine for criminals. Its ease of use, proxy rotation, and flexible configuration lower the barrier to credential stuffing attacks, making robust rate limiting, fingerprinting, and behavioral challenges essential defenses. Organizations must assume that tools like OpenBullet will be used against them and design authentication systems to resist automated, low‑volume, distributed guessing – not just high‑speed brute force. openbullet
