VECTOR 01 // ADVERSARY SIMULATION

Offensive Web, API & Mobile Penetration Testing

Practitioner-led manual penetration testing targeting Broken Object Level Authorization (BOLA), multi-tenant privilege escalation, and business logic flaws with 100% zero automated scanner noise.

METHODOLOGY

4-Phase Offensive Execution Framework

PHASE 01

Surface Mapping

API contract discovery, OpenAPI parsing, JWT state machine reverse engineering, and unauthenticated endpoint indexing.

PHASE 02

Adversary Simulation

Manual exploitation of multi-tenant boundaries, IDOR, race conditions in ledger updates, and token scope bypasses.

PHASE 03

Code Remediation

Drafting verified drop-in code diffs, CVSS 3.1 ratings, executive briefs, and developer walkthrough calls.

PHASE 04

30-Day Retest

Complete re-verification of all deployed patches, Letter of Attestation, and audit evidence sign-off.

Target Attack Surfaces

Single Page Applications: React, Vue, Next.js, and Angular client logic flaws.
API Backbones: REST, GraphQL, gRPC, and WebSocket microservice layers.
Mobile Clients: iOS & Android binary inspection, certificate unpinning, and token storage.
Financial & Core Logic: Payment gateway state machines, coupon stacking, and ledger race conditions.

Deliverables & Assurance

Standardized 7-Page Executive Deliverable (PDF): CISO & Board-ready risk narrative.
Actionable Code Remediation Diffs: Exact drop-in code fixes in Python, Go, TypeScript, or SQL.
Step-by-Step Exploit PoCs: 100% reproducible exploit scripts with zero false positives.
Formal Letter of Attestation: Independent third-party validation for CPA/audit compliance.
