| name | performing-ios-app-security-assessment |
| description | Performs comprehensive iOS application security assessments using Frida for dynamic instrumentation, Objection for runtime exploration, SSL pinning bypass for traffic interception, keychain extraction for credential analysis, and IPA static analysis for binary-level review. Use when conducting authorized iOS penetration tests, evaluating mobile app security posture against OWASP MASTG, or assessing iOS app data protection and transport security controls. Activates for requests involving iOS app pentesting, Frida-based iOS instrumentation, mobile app SSL pinning bypass, or IPA reverse engineering.

Performing iOS App Security Assessment
Disclaimer
This skill is intended for authorized security testing, penetration testing engagements, CTF competitions, and educational purposes only. Unauthorized access to applications or devices is illegal. Always obtain written authorization before performing any security assessment. Misuse of these techniques may violate computer fraud and abuse laws in your jurisdiction.
When to Use
Use this skill when:
- Conducting authorized penetration tests of iOS applications against OWASP MASVS/MASTG criteria
- Performing dynamic analysis of iOS apps using Frida instrumentation and Objection runtime exploration
- Bypassing SSL/TLS certificate pinning to intercept and analyze app network traffic through a proxy
- Extracting and auditing iOS Keychain contents for insecure credential storage practices
- Performing static analysis of IPA packages to identify hardcoded secrets, entitlements, and binary protections
- Assessing jailbreak detection and anti-tampering controls in iOS applications
Do not use against applications without explicit written authorization. Do not use on production devices containing real user data unless the engagement scope permits it.
Prerequisites
- Python 3.10+ with pip
- Frida toolkit:
pip install frida-tools frida
- Objection:
pip install objection
- Target iOS device (jailbroken with frida-server, or non-jailbroken with patched IPA)
- macOS with Xcode command-line tools (recommended for code signing and ideviceinstaller)
- Burp Suite or mitmproxy for traffic interception after SSL pinning bypass
- For jailbroken devices: SSH access and frida-server running on the device
- For non-jailbroken devices: Apple Developer certificate for IPA re-signing
Workflow
Step 1: IPA Static Analysis
Extract and analyze the IPA binary before runtime testing:
unzip target.ipa -d target_app/
otool -hv target_app/Payload/*.app/AppExecutable
otool -l target_app/Payload/*.app/AppExecutable | grep -A4 LC_ENCRYPTION
plutil -p target_app/Payload/*.app/Info.plist
strings target_app/Payload/*.app/AppExecutable | grep -iE "api[_-]?key|secret|password|token|firebase"
security cms -D -i target_app/Payload/*.app/embedded.mobileprovision
otool -L target_app/Payload/*.app/AppExecutable
