Authentication

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

Techniques

TypeKey Vectors
Auth BypassDefault credentials, logic flaws, response manipulation
ADFS/SAMLGolden SAML, token signing cert theft, assertion manipulation, SAML wrapping
JWTAlgorithm confusion, key injection, claim tampering, token forging
OAuthRedirect manipulation, CSRF, token leakage, scope abuse
PasswordBrute force, credential stuffing, password policy bypass
2FA BypassResponse manipulation, direct endpoint access, code reuse, race conditions
CAPTCHA BypassMissing server validation, token reuse, OCR, parameter manipulation
Bot DetectionBehavioral 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

Acquire an authenticated session THROUGH MFA/OTP on an in-scope target and emit a reusable session artifact (Playwright storageState + Bearer) so executors can test the post-auth attack surface. Use when the highest-value authenticated classes (BOLA/IDOR/mass-assignment/injection on the real data APIs) are blocked because login is gated by SMS-OTP or TOTP MFA. Distinct from the authentication skill (which ATTACKS auth); this one legitimately authenticates and hands the session to the rest of the engagement.
