Authentication

Test authentication mechanisms including login security, token handling, 2FA, CAPTCHA, and bot detection.

Techniques

Type Key Vectors
Auth Bypass Default credentials, logic flaws, response manipulation
ADFS/SAML Golden SAML, token signing cert theft, assertion manipulation, SAML wrapping
JWT Algorithm confusion, key injection, claim tampering, token forging
OAuth Redirect manipulation, CSRF, token leakage, scope abuse
Password Brute force, credential stuffing, password policy bypass
2FA Bypass Response manipulation, direct endpoint access, code reuse, race conditions
CAPTCHA Bypass Missing server validation, token reuse, OCR, parameter manipulation
Bot Detection Behavioral biometrics simulation, fingerprint randomization, stealth mode

Tools

PasswordGenerator (tools/password_generator.py):

from tools.password_generator import generate_password
password = generate_password(hint_text="8-16 chars, uppercase, numbers")

CredentialManager (tools/credential_manager.py):

from tools.credential_manager import CredentialManager
mgr = CredentialManager()
mgr.store_credential(target="example.com", username="test", password="pass")

Workflow

  1. Analyze auth implementation (forms, tokens, 2FA, CAPTCHA)
  2. Test bypass vectors per technique type
  3. Use Playwright MCP with human-like behavior (typing 80-200ms, random pauses)
  4. Capture evidence (screenshots, network logs, tokens)
  5. Document findings with PoC scripts
