Malicious USB Shooting

I am not sure if is a change or a bug, so i decided to report it - i am sorry, i do not have any clips of it, as i had just woken up.

I used the white USB to make a malicious, once the loading was done, i received a “you were hack, be careful” (something along those lines) notification and was shot my invisible locals.

I am not sure if is a change or was just a bug, but just was odd to be shot without being able to see them or how they even got inside my warehouse.
