Mobile Security

Probe the Backend APIs That Actually Power Your Mobile App

The riskiest attack surface isn't the mobile binary — it's the backend it talks to. The scanner extracts endpoints from the mobile app (or a HAR capture) and runs API-focused checks: auth, BOLA, mass-assignment, JWT, rate-limit, and data exposure.

How It Works

From target input to actionable findings in three straightforward steps.

01

Supply the Endpoints

Upload a HAR file captured from the app, or paste the base URL if the API surface is already known.

02

Authenticate the Scanner

Paste a bearer token or a refresh-token flow so the scanner can reach authenticated endpoints.

03

API-focused Scan

Every endpoint is tested for auth / authorization / injection / business-logic weaknesses.

Key Capabilities

Purpose-built scanning backed by real penetration testing expertise.

HAR Import

Capture the mobile app with a MITM proxy and upload — we derive the complete endpoint list automatically.

Auth Variants

Bearer, custom header, refresh-token flow supported out of the box.

BOLA + BFLA

Attempts to access other users / tenants resources to surface broken object- and function-level authorization.

Mass-Assignment

Sends extra fields (role, admin, tenant_id) on write requests to spot missing field filters.

JWT Weakness

If the app uses JWT, the scanner inspects signing, expiry, and claim handling.

Rate-Limit Probe

Fires bursts to see whether login / password-reset / search endpoints throttle correctly.

Common Use Cases

Audit the backend before launching a new mobile app version
Regression test after a backend refactor
Spot leaked tokens in an access-log dump
Pre-engagement reconnaissance on authorized mobile targets
Validate BOLA fixes before closing a bug ticket
Sanity-check third-party SaaS the app integrates with

Frequently Asked Questions

Do I need the source code?
No. A HAR file or a base URL is enough to start.
Does this test the app UI?
No. This tool tests the backend APIs. Use the APK / IPA Analyzers for binary-level checks.
Is my HAR stored?
No. The HAR is parsed in memory and discarded after the scan.
