Methodology + Threat Model
Human-led
We define scope, trust boundaries, and likely attacker goals for your exact environment.
Mobile Security
iOS and Android assessment for client runtime and backend trust failures
We test how your mobile client behaves under adversarial conditions, then validate whether backend services still enforce trust boundaries when device assumptions break.
Engagement Duration
5-10 business days
Primary Outcome
A practical remediation plan covering client hardening, API trust controls, and reproducible validation for engineering teams.
Human-led
We define scope, trust boundaries, and likely attacker goals for your exact environment.
AI-assisted
Automation surfaces anomalous behavior, edge cases, and high-value paths worth manual attention.
Human-led
Every reported finding is manually reproduced and impact-tested before inclusion.
Collaborative
We deliver developer-ready fixes and perform a free retest after your patch window.
Inconsistent token handling between foreground/background app states
Sensitive data remnants in local storage, logs, or crash artifacts
Client-side checks that can be bypassed before API requests are sent
Backend trust assumptions tied to mutable device attributes
We evaluate how resilient the app is when an attacker controls the device context, instrumentation layer, or local state.
Local data handling in keychain/keystore and app storage
Transport protections including pinning behavior validation
Root/jailbreak and runtime tamper resistance checks
Sensitive artifact exposure in logs, cache, and backups
AI flags suspicious request patterns and state transitions; analysts validate whether backend authorization still holds after client compromise.
Token lifecycle integrity and session invalidation behavior
Backend authorization independence from client-side controls
Parameter tampering, replay, and sequencing abuse
Error handling and metadata leakage under adversarial requests
