MSF ::EXITFUNC::

Quick note about MSF EXITFUNC.


So what is EXITFUNC?

EXITFUNC option is set to 'thread' by default, and it works fine in most cases, so we don't usually look into it much. But in some situations specifying a different EXITFUNC is necessary so that you can have a clean exit from the exploited box.

There are 3 different values for EXITFUNC:

  • THREAD: This method is used in most exploitation scenarios where the exploited process (e.g. IE) runs the shellcode in a sub-thread and exiting this thread results in a working application/system (clean exit)
  • PROCESS: This method should be used with multi/handler. This method should also be used with any exploit where a master process restarts it on exit.
  • SEH: This method should be used when there is a structured exception handler (SEH) that will restart the thread or process automatically when an error occurs.
Might be useful when we wanted to generate a payload with MSFVENOM.

iOS - Convert .app to .ipa

While doing a iOS Security Testing, I wondered how do we convert .app into .ipa. So basically here are the structure of .ipa files. 1. First, SSH in your iPhone (Jailbroken). 2. Download the .app folder via scp  3. Copy the .app folder into a folder called Payload. 4. Compress it with .zip extension using any compression software. 5. Change the extension from file.zip to file.ipa. That’s it. Now you can use these .ipa files to install the app into your iPhone.
