Bypass iOS Version Check and Certification Validation

At 3 PM PDT on May 23, 2020, the unc0ver jailbreak was released for iOS 13.5 (the latest signed version at the time of release) using a zero-day vulnerability and heavy obfuscation. By 7 PM, I had identified the vulnerability and informed Apple. By 1 AM, I had sent Apple a POC and my analysis. This post takes you along that journey.

NetSPI's open LLM security benchmark tests how large language models resist jailbreaks under adversarial conditions while measuring the security-usability trade-off in enterprise deployments.

Ben Tindell covers four iOS SSL pinning bypass techniques with Burp Suite: installing a custom CA, SSLKillSwitch tooling, runtime hooking with Objection and Frida, and patching the IPA binary.

Updates earlier iOS 7 GDB-based memory dumping to iOS 8, walking through using LLDB, debugserver, and tcprelay on a jailbroken device to extract an application's memory.

This iOS tutorial automates heap dumping: after decrypting the binary with Clutch and running class-dump-z, generated Cycript scripts pull targeted properties and instance variables from memory.

Without root, testers can attach a debugger to Android apps after decompiling with APKTool, stepping through method calls to intercept traffic pre-encryption and capture keys never written to disk.
