Hooking Básico
Agora que você enumerou as classes e módulos usados pelo aplicativo, pode ter encontrado alguns nomes de classes e métodos interessantes .
Hooking todos os métodos de uma classe
ios hooking watch class <class_name>
: Hook todos os métodos de uma classe, despeje todos os parâmetros iniciais e retornos
Copy ios hooking watch class iGoat_Swift.PlistStorageExerciseViewController
Hooking um único método
ios hooking watch method "-[<class_name> <method_name>]" --dump-args --dump-return --dump-backtrace
: Hook um método específico de uma classe despejando os parâmetros, backtraces e retornos do método cada vez que é chamado
Copy ios hooking watch method "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" --dump-args --dump-backtrace --dump-return
Alterar Retorno Booleano
ios hooking set return_value "-[<class_name> <method_name>]" false
: Isso fará com que o método selecionado retorne o booleano indicado
Copy ios hooking set return_value "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" false
Gerar template de hooking
ios hooking generate simple <class_name>
:
Copy ios hooking generate simple iGoat_Swift.RCreditInfo
var target = ObjC.classes.iGoat_Swift.RCreditInfo ;
