iOS Application Runtime Analysis

Scope

Use this module only for authorized/owned iOS applications to trace Objective-C/Swift method calls, inspect keychain entries, and validate entitlements.

Workflow

1. Confirm application ownership and establish jailbroken test device.
2. Identify binary architecture and load into runtime analysis tool.
3. Trace Objective-C message sends and Swift function calls of interest.
4. Inspect keychain items belonging to the application's access group.
5. Dump and validate entitlements from the embedded provisioning profile.
6. Document data protection classes applied to stored files.
7. Summarize runtime behavior and security posture.

Safety Rules

• Do not analyze applications without explicit ownership or written authorization.
• Do not extract or exfiltrate keychain items from other applications.
• Do not tamper with code signing or provisioning on non-owned apps.
• Do not bypass platform security controls for unauthorized access.

Output

Return evidence table with columns: Component | Finding | Data Protection Class | Risk Assessment.
