The application you're trying to target may have been automatically updated since you've last looked at it or something of that nature. So, this is very unlikely to be wrong and I would have to refer you to the Security Protections article. When task_for_pid fails, Bit Slicer invokes codesign -dv on the target binary and shows this error when the binary is signed with protections ( runtime, restrict) that would prevent Bit Slicer from debugging it. 's memory cannot be searched due to system protections. Because it fails, it may not bring up an authentication prompt if needed (debuggers like Bit Slicer only need to request for successful auth once per system boot). Visit the Scripting Functions page for reference.Task_for_pid() on the specific app/game you're targeting is failing here. vm has a set of methods for actions such as reading, writing, and scanning, and debug has a set of methods for logging and for utilizing the debugger. When Bit Slicer runs your script, it first creates these two objects. You may have been noticing two objects that have been used in these scripts: vm and debug. Hopefully the rest of the script is self-explanatory enough. (I didn't have to do this, but I think it's good practice.) In execute we increment our time accumulator timePassed and decrease it once we've waited for TIME_INTERVAL seconds. Up top I decided to initialize some constants. Finally, when the user is finished running the script, the speed is reverted back to the way it was before. This script initially modifies the speed variable, then every 1 second, it increases the speed variable by 1. #restore speed back to the way it was before the script ran vm. #look up python formatters if you're wondering what %d is debug. timePassed -= TIME_INTERVAL def finish( self): timePassed += deltaTime #every TIME_INTERVAL, increase speed by 1 if self. timePassed = 0.0 def execute( self, deltaTime): #Increase Speed! from bitslicer import VirtualMemoryError, DebuggerError #memory address to 32-bit speed integer SPEED_ADDRESS = 0x1A168 #initial starting speed START_SPEED = 10 #how frequently time should change in seconds TIME_INTERVAL = 1.0 class Script( object): Here is another more interesting example (this isn't specific to any particular game by the way, and the memory addresses used below are made up): (Just to note: this is an incomplete explanation.) Another Example Every method has self passed in as the first argument. If you're unfamiliar with Python and its concept of classes, self is basically a table used to share data from one method to another. When the user deactivates your script, finish is called if it's implemented. In this example, execute is not implemented and commented out. When the script starts running, _ init_ is called.Īfter that, execute is called frequently (approximately every 0.03 seconds) if it's implemented deltaTime (delta as in "change in") is the time in seconds that has passed since execute was last called, as a floating point. When a user activates a script, Bit Slicer will create an instance of the "Script" class and call the methods _ init_, execute, and finish. #def execute(self, deltaTime): #write some interesting code, or don't implement me def finish( self): #Edit Me! from bitslicer import VirtualMemoryError, DebuggerError class Script( object): (Note: the template uses space characters by default for indentation and Python cares a lot about indentation.) You will see a template of code already filled out. This will open it into a text editor (it will use the one that is associated with python. Double click on the script variable's value. You will see your script printed out two lines in there.
