| 13 | optool v0.1 |
| 14 | |
| 15 | USAGE: |
| 16 | install -c <command> -p <payload> -t <target> [-o=<output>] [-b] [--resign] Inserts an LC_LOAD command into the target binary which points to the payload. This may render some executables unusable. |
| 17 | |
| 18 | uninstall -p <payload> -t <target> [-o=<output>] [-b] [--resign] Removes any LC_LOAD commands which point to a given payload from the target binary. This may render some executables unusable. |
| 19 | |
| 20 | strip [-w] -t <target> Removes a code signature load command from the given binary. |
| 21 | |
| 22 | restore -t <target> Restores any backup made on the target by this tool. |
| 23 | |
| 24 | aslr -t <target> [-o=<output>] [-b] [--resign] Removes an ASLR flag from the macho header if it exists. This may render some executables unusable |
| 25 | |
| 26 | |
| 27 | OPTIONS: |
| 28 | [-w --weak] Used with the STRIP command to weakly remove the signature. Without this, the code signature is replaced with null bytes on the binary and its LOAD command is removed. |
| 29 | |
| 30 | [--resign] Try to repair the code signature after any operations are done. This may render some executables unusable. |
| 31 | |
| 32 | -t|--target <target> Required of all commands to specify the target executable to modify |
| 33 | |
| 34 | -p|--payload <payload> Required of the INSTALL and UNINSTALL commands to specify the path to a DYLIB to point the LOAD command to |
| 35 | |
| 36 | [-c --command] Specify which type of load command to use in INSTALL. Can be reexport for LC_REEXPORT_DYLIB, weak for LC_LOAD_WEAK_DYLIB, upward for LC_LOAD_UPWARD_DYLIB, or load for LC_LOAD_DYLIB |
| 37 | |
| 38 | [-b --backup] Backup the executable to a suffixed path (in the form of _backup.BUNDLEVERSION) |
| 39 | |
| 40 | [-h --help] Show this message |
