iOS Kernel Symbol Offset Finder

Don't ya just hate it when PoC's for iOS exploits are hardcoded to work with one specific device model on one specific subversion of iOS, instead of just dynamically finding the offsets it requires?

Be annoyed no more - IKSOF finds all^_* those symbol offsets for you and even outputs them in a nice header file as macros.

Usage

It's super easy to use:

1. Download the ipsw for the target device and iOS version
2. Run this command:

iksof --ipsw <path-to-ipsw>

• note: unless you configure your shell otherwise, you need the full path to the iksof command

Currently Supported Symbols

^_*all - all of the offsets seen here:

| Name | |---| | _kernel_map | | _kernel_task | | _bzero | | _bcopy | | _copyin | | _copyout | | _rootvnode | | _kauth_cred_ref | | _ZNK12OSSerializer9serializeEP11OSSerialize | | _address_host_priv_self | | ipc_port_alloc_special | | _ipc_kobject_set | | ipc_port_make_send | | _rop_add_x0_x0_0x10 | | _zone_map | | _iosurfacerootuserclient_vtab |

That's not a whole lot right now - but since it's enough enable using an (albeit older) exploit that's out there, I'm putting out out into the public as a prerelease. LOTs more will be added soon.
