Performing Ios App Security Assessment

Overview

Cybersecurity skill for performing ios app security assessment. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing ios app security assessment"
• "Conducting authorized penetration tests of iOS applications against OWASP MASVS/"
• "Performing dynamic analysis of iOS apps using Frida instrumentation and Objectio"
• "Bypassing SSL/TLS certificate pinning to intercept and analyze app network traff"

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.

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

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

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": ,
    : ,
    : ,
}

 () -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
