This script inspects iOS application binaries to uncover usage of insecure functions, implementation of weak cryptography, encryption status, code signature and the presence of security features like Position Independent Executable (PIE), Stack Canaries, and Automatic Reference Counting (ARC). It also performs checks on Dynamic Library dependencies, and potential anti-analysis/debugging symbols.

• Quick static analysis of iOS binaries.
• Checks for core binary security mitigations (Encryption, Code Signature, PIE, Stack Canaries, ARC).
• Detection of weak cryptographic methods (MD5, SHA1).
• Identification of commonly misused and insecure C functions.
• Analysis of Dynamic Library dependencies (otool -L) to spot potential vulnerable frameworks.
• Detection of debugging and anti-analysis symbols (e.g., ptrace, fork).

1. 📲 Jailbreak your iOS device. : rootfull or rootless
2. 🛠️ Install otool: This can be done through the Cydia package manager.
   • Add the following repository in Cydia: http://apt.thebigboss.org/repofiles/cydia/
   • Search for and install the Big Boss Recommended Tools package.
   • Alternatively, search for and install the Darwin CC Tools package.
   • If your device is set up with SSH and command line access, you can also install otool via command line using: apt install otool

The binary should be located within the /private/var/containers/Bundle/Application/XXXXXXX/<APP-PATH>/ directory. Or in /var/containers/Bundle/Application/XXXXXXX/<APP-PATH>/ if installed with TrollStore.

# on host
git clone https://github.com/saladandonionrings/ios-binary-checks.git

# send the script to your ios device
scp check-binary.sh root@ip:/var/root
# on ios device
./check-binary.sh <binary>
