Packet Tracer .pka activities question

[Andrew112]

I am new to using packet tracer, and a bit inexperienced with this kind of software and IT in general. I wanted a bit of clarification on how my pc interacts with .pka activities specifically. It seems PT is a simulation so it’s relatively limited and sandboxed compared to GNS3 for example. What I’d like to know is can packet tracer connect to my local machine, whether that is through my network or accessing my local files through the application without my permission. I see an option in settings for external network access from script modules for example. I also noticed you can code devices under their programming tab in python or java. If I were to run a random .pka file from the internet or another student for example, could there be anything preconfigured in the lab or scripts that would import any of my files or network data without my permission? Or would I have to go out of my way to install extensions/allow access.. I will probably be exchanging .pka files between my classmates and instructors so I would rather not have any of my personal data stored in them. Thank you.

Hello @Andrew112 

Packet tracer with *.pka files are typically safe and self-contained within the packet tracer environment. They don't have the capability to directly interact with your local machine or access files outside the Packet Tracer application. When you run a .pka file, it operates within the Packet Tracer simulation environment and doesn't have direct access to your computer's resources or network.

The "external network access from script modules" option you mentioned is more related to scripting within Packet Tracer. It doesn't allow Packet Tracer to access external resources on your machine; rather, it's about scripting within the simulation environment.

The .pka files are meant to simulate networking scenarios and configurations. They include information about routers, switches, PCs, and their configurations, but they don't contain executable code that could harm your computer or access your local files.

It's always good to be cautious when exchanging files, especially from sources you don't entirely trust. However, in the context of Packet Tracer files, the risk is minimal, and you can review the contents of a .pka file by opening it in Packet Tracer before running it to ensure it matches the expected networking scenario.

Great thank you for explaining this in detail for me. I was not completely sure about running unknown .pka files so this helps a lot.
