In short macOS will only verify code signature upon first execution, anything changes after that will be undetected. Sublime has a code signature and hash for this script, the reason macOS will not block tampering with the script, was covered by Thomas Reed in his talk about “Code Signing flaw in macOS“: You will get a prompt on Mojave to grant access, but you can add other code, which would do something else to avoid this prompt, and even if you get it, an average user will just grant access. system( "osascript -e 'Tell application \" System Events \" to display dialog \" Message \" '")

Second, you install it by drag & drop to the application folder, so the user has the rights to edit the script file. This is a very popular text editor application, so you are likely to find it somewhere. So it’s not that ideal, but it works if really needed. Even if you persist, you will only maintain yourself as the user and not as root. I have two problems with this, one is that finding this app somewhere is very unlikely, the second is that as you have to install this, the folder permissions are set for root access only. The app or the OS doesn’t verify if the script was tampered with. This application has a idlemain.py script in the resources folder, that is executed upon starting Idle. Python3 Idle.appĪlthough it’s probably not that common people installing Python on a macOS system, as it’s present by default, but if so, it contains the Idle.app editor. The question is if there are any other scripts that will always run, and the answer is yes. You could also go about infecting every possible script you find, increasing the chances of being executed. There is a chance that you can find a frequently run script somewhere, but those would require a check one by one, which I didn’t do. The problem with these that we don’t know when they will be called, possibly it’s not so frequent, so they are not ideal for persistence, as we want something that is always invoked when an applications starts.
