Performing Mobile App Certificate Pinning Bypass

Performing Mobile App Certificate Pinning Bypass

Overview

Cybersecurity skill for performing mobile app certificate pinning bypass. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing mobile app certificate pinning bypass"
• "Bypasses SSL/TLS certificate pinning implementations in Android and iOS applicat"

Use this skill when:

• Mobile app refuses connections through a proxy due to certificate pinning
• Performing authorized security testing requiring HTTPS traffic interception
• Assessing the strength and bypass difficulty of pinning implementations
• Evaluating defense-in-depth of mobile app network security

Do not use to bypass pinning on apps without explicit testing authorization.

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

• Burp Suite configured as proxy with listener on all interfaces
• Rooted Android device or jailbroken iOS device
• Frida server running on target device
• Objection installed (pip install objection)
• Target app installed and reproducing the pinning behavior

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
