Almost every program that we run has access to the environment, so nothing stops them from curling our credentials to some nefarious server.
Why don’t we put credentials in files and then pass them to the programs that need them? Maybe coupled with some mechanism that prevents executables from reading any random file except those approved.
I am not familiar with the software bubblewrap so I am just picturing your hard drives wrapped up inside your case.
That’s an old white-hat trick. If the tables drop, the wrap helps them bounce.
