[TheFreakzz 50 iPhone 11 Pro 13.5.1]

Name of the game you want hacked:Iron Blade: Medieval RPG 
Version of the game: 2.3.0
iTunes Link for the app: 
Jailbroken or Non-Jailbroken: Jailbroken 

Requested Features: Enemy dont Attack
 

[xrayactual 6 iPhone 11 Pro Max 14.3]

@TheFreakzz FYI: This app has anti-debugging enabled, making it more difficult to hack. It is also not an il2cpp or unity game so finding methods that are exploitable could be near impossible. Also cannot "uncar" Assets.car to search for potential exploits

IDA might help disable the anti-debugger but methods likely cannot be deciphered in bulk if they are obfuscated.

Update: This game uses syscall and sysctl to prevent debugging

@xrayactualDon't understand much about it, but is there a small hope of hacking the game, or impossible?

I don't know yet, I don't have enough information as I'm waiting for my mac to finish transferring the decrypted files to my windows computer so I can try to disable the debugger.

Hackers FYI: within IronBladeSlice.app/Payload/app_package/behaviors/ is a file labeled "AIEnemy.dat", that's probably what dictates AI behavior, i.e. ignore player, but I don't know for certain

@xrayactualI understand. That would be really great if it works. Enemy dont Attack would do just fine as a hack. But thanks for trying that.

I don't have any experience in manipulating dat files so that may be in Zahir's realm.
I'm still scanning for iterations of _syscall and _sysctl within the assembly, if I can recompile it without issue we may have a starting point...

Additional findings: Iron Blade Medieval runs memory checks, and premium currency is held within 5 memory addresses

Update:

Its littered with antidebugging 🤣 98 total calls, will update when I make more progress

_sysctl:

@xrayactualI asked Zahir and I think he'll take a look. I hope he will have time for that . I told him I'll check back on Sunday to see if he was successful.

@xrayactualso the game is impossible to hack, right?

As far as I can tell, yes. Trying a few other tricks but at this time patching the anti-debuggers is not possible

[TheFreakzz 50 iPhone 11 Pro 13.5.1]

I understand. Unfortunately I could no longer reach Zahir in the chat box. But if you know something new, please let me know👍
