🛡️ AUTHENTIX v3.0.0 — Enterprise Slide Deck
SLIDE 1 OF 12
SLIDE 01 • OVERVIEW

AUTHENTIX v3.0.0: Enterprise Security Suite for Burp Suite

An autonomous AppSec intelligence engine engineered on the native PortSwigger Montoya API. Eliminates reliance on noisy heuristic scanners by validating authentication workflows through deterministic state machines, 3-way differential testing, and formal mathematical invariants.

Montoya API Native

Direct low-overhead integration into Burp Suite Proxy, Repeater, Scanner, and Intruder without legacy interfaces.

State Machine Automaton

Models authenticated actor lifecycles as a directed graph to discover horizontal/vertical privilege escalation.

14,880 Req/Sec Engine

Asynchronous multi-threaded worker pools guarantee zero lag or packet dropping in high-volume proxy environments.

SLIDE 02 • THE PROBLEM

Why Conventional Scanners Fail on Multi-Step Auth & IDOR

Traditional vulnerability scanners inspect individual HTTP requests in isolation. They lack conversational memory, actor attribution, and session lifecycle awareness, resulting in missed Broken Object Level Authorization (BOLA), multi-tenant escapes, and Account Takeover (ATO) flaws.

Stateless Request Blindness

Inability to track state changes between Pre-Auth, MFA, Authenticated, and Post-Logout phases.

Soft-200 Misinterpretations

Application errors returning HTTP 200 with JSON error payloads trigger massive false-positive alerts in traditional DAST.

No Multi-Step ATO Synthesis

Fails to correlate individual low-severity signals (e.g. account enumeration + weak reset) into critical kill chains.

SLIDE 03 • THE SOLUTION

The AUTHENTIX Paradigm: Invariant-Driven Security

Instead of guessing vulnerabilities through brute force, AUTHENTIX mathematically monitors state transitions against 34 formal security invariants. When an invariant is violated, an exploit is mathematically proven to exist.

34 Formal Invariants

Enforces strict properties: OTP single-use, session invalidation on password change, token entropy thresholds.

3-Way Differential IDOR

Triangulates authorization across Victim, Attacker, and Anonymous sessions with Soft-200 error disambiguation.

Instant Kali cURL PoC

Generates multi-line reproduction commands directly executable in terminal for rapid proof-of-concept verification.

SLIDE 04 • PIPELINE ARCHITECTURE

Deterministic Flow Graph & Pipeline Engine

HTTP traffic is captured via Montoya API -> TrafficInterpreter classifies flow -> FlowGraphEngine tracks actor state -> Invariant & File Engines evaluate rules -> AttackPathCorrelator synthesizes compound chains -> FlatLaf UI & Telegram dispatch.

SLIDE 05 • 3-WAY DIFFERENTIAL IDOR

Empirical BOLA Verification with Soft-200 Filter

Substitutes credentials across multiple actor personas simultaneously. Disambiguates soft-200 application errors (e.g. {"error": "unauthorized"} returning HTTP 200) ensuring 0.0% false positives.

Victim Context (Alice)

GET /api/accounts/201 with Alice session cookie → HTTP 200 OK (Owner: Alice).

Attacker Context (Bob)

GET /api/accounts/201 with Bob session cookie → HTTP 200 OK (Owner: Alice) = 🚨 BOLA CONFIRMED!

Anonymous Baseline

GET /api/accounts/201 without cookies → HTTP 401 Unauthorized (Confirms endpoint is private).

SLIDE 06 • PATH NORMALIZATION & TENANT BYPASS

Advanced Perimeter & Multi-Tenant Invariants

Engine expanded to detect Spring semicolon path traversal (..;/), URL-encoded traversal (..%2f), proxy override headers (X-Original-URL), and tenant context swapping (X-Tenant-Id).

Path Normalization (CWE-863)

Injected Spring semicolons bypass API Gateway routing rules, allowing direct invocation of internal admin methods.

Tenant Boundary Swap

Manipulating `X-Tenant-Id` headers allows lateral cross-tenant data harvesting across corporate partitions.

Mass Assignment (CWE-915)

Accepts unprivileged role attribute binding during user profile updates, elevating privileges to super-admin.

SLIDE 07 • 16 COMPOUND ATO CHAINS

16 Correlated Attack Chains: Full ATO Kill Chains

Synthesizes independent low/medium severity findings into catastrophic compound exploits that lead to complete organizational takeover.

[Chain #15: Gateway Perimeter Bypass] Path Normalization (Inv 33) + Broken Function Level Auth (Inv 15) ➔ Attacker injects: /api/..;/admin/users ➔ Gateway perimeter authentication bypassed ➔ Administrative user export dumped! [Chain #16: Multi-Tenant Data Breach] Multi-Tenant Header Swap (Inv 34) + Cross-Actor IDOR (Inv 14) ➔ Injects X-Tenant-Id: victim_corp ➔ Accesses scoped invoice records across tenant boundary!
SLIDE 08 • NATIVE BURP FLATLAF UI

Native Burp Suite Integration & 1-Click Repeater

Seamlessly inherits Burp Suite FlatLaf Darcula styling tokens. Double-click any finding to instantly dispatch the raw request into Burp Repeater for immediate reproduction.

Double-Click Repeater

Instantly creates a new tab in Burp Repeater with full headers and payload ready to resend.

Enterprise Inquiries

Architected and maintained by Pratik Khairnar (@pratik-khairnar-sec).

Zero False Positive Innovation

3-Way Differential Cross-Actor IDOR Engine

Triangulates authorization across multiple active actor sessions and eliminates soft-200 application errors.

SESSION A (ALICE / VICTIM)

Target Resource Request

Alice requests her private savings account details.

GET /api/accounts/201 HTTP/1.1 Host: nimbusbank.test Cookie: sid=alice_session_9a7f HTTP/1.1 200 OK {"id": 201, "owner": "Alice", "balance": 14850.00}
SESSION B (BOB / ATTACKER)

Cross-Actor Token Substitution

Bob sends his session cookie requesting Alice's account.

GET /api/accounts/201 HTTP/1.1 Host: nimbusbank.test Cookie: sid=bob_session_3b2c HTTP/1.1 200 OK 🚨 CONFIRMED IDOR {"id": 201, "owner": "Alice", "balance": 14850.00}
ANONYMOUS BASELINE

Unauthenticated Verification

Confirms endpoint is genuinely private and protected.

GET /api/accounts/201 HTTP/1.1 Host: nimbusbank.test [No Authorization Headers] HTTP/1.1 401 Unauthorized {"error": "Authentication required"}

Soft-200 Application Error Disambiguation Algorithm

If an endpoint responds with HTTP status 200 but contains keys like {"error": "unauthorized"} or {"status": 403}, traditional scanners trigger false-positive alerts. AUTHENTIX passes all responses through TrafficInterpreter.isApplicationError(), which checks for internal error signatures, status codes, and message bodies before invariant evaluation.

Correlated Exploitation

16 Compound Account Takeover (ATO) Attack Chains

Linking individual low/medium severity findings into devastating P1/P2 attack narratives.

CHAIN #15 (NEW IN v3.0) CRITICAL

Path Normalization + BFLA → Gateway Perimeter Bypass

Injected Spring semicolon path traversal or proxy override headers bypass API gateway authentication filters to invoke administrative operations.

1. Injected Spring traversal: /api/..;/admin/users
2. API Gateway perimeter access control bypassed
3. Administrative user list exfiltrated without auth
CHAIN #16 (NEW IN v3.0) CRITICAL

Multi-Tenant Header Swap + IDOR → Multi-Tenant Data Breach

Manipulating tenant context headers combined with entity ID parameters permits unauthorized lateral movement across organization partitions.

1. Tenant context header injected: X-Tenant-Id: victim_corp
2. Target object ID probed: /api/invoices/9904
3. Cross-tenant financial records dumped with HTTP 200
CHAIN #05 CRITICAL

Pre-Auth OTP Leak in Response → 0-Click Takeover

Initiating 2FA or password reset leaks active verification code in API response, enabling instant zero-interaction account takeover.

1. POST /api/auth/login triggers SMS/email OTP dispatch
2. JSON response body reflects plaintext code: {"otp": "4819"}
3. Attacker submits code → Immediate Account Takeover
CHAIN #13 (NEW IN v3.0) HIGH

Mass Assignment + Client RBAC Bypass → Admin Escalation

Tampering with client-side UI flags paired with hidden JSON parameter binding elevates standard user accounts to super-admin privileges.

1. Discovers client-side role guard in React router
2. Injects {"role": "admin", "isAdmin": true} in profile PUT
3. Backend binds parameters without filter → Full Admin Portal
Deep Client-Side & API Analysis

30+ Deep Secret Detection Rules

Continuous regex and Shannon entropy inspection ($H \ge 3.5$) of HTTP responses and JavaScript assets.
