Security audit

Mobile MVC

Security checks for vulnerabilities and agentic risk

Overview

This skill provides proportionate guidance for improving mobile app code through small, tested changes.

Use this as refactoring guidance: review proposed changes and run the application's tests. The skill requires no credentials or external service configuration. Its examples are illustrative and should be adapted to your project.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

| Found in the view controller | Move it to |
|---|---|
| `URLSession`, request building, JSON decoding | A service or repository protocol, injected through `init` |
| Core Data, SwiftData, file or Keychain access | A store type behind a protocol |
| Date, number, measurement formatting | Row or display models built from domain models |
| Input validation | A pure validator type with unit tests |
| `UITableViewDataSource`, `UICollectionViewDataSource` | A diffable data source plus a cell provider |

External Transmission

Data Exfiltration
Confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
