  • If paying on a monthly basis, as soon as you pay for 12 consecutive months, you will receive this perpetual fallback license providing you with access to the exact product version for when your 12 consecutive months subscription started. You will receive perpetual fallback licenses for every version you’ve paid 12 consecutive months for.

    So, in your example, you unsubscribe in month 15. This means, you paid 14 months so you get to retain the version from month three (which is 12 full paid months to 14). This means a downgrade to 1.0.x and not to 1.2.x






  • 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.


  • Never thought about that, but since these tools just work, when you copy them to your PC… how does psexec do that? It’d either need you to be an administrator (and then it’s not really a privilege escalation as you could have registered any program into the task scheduler or as a service to run as SYSTEM) or it’d need a delegate service, that should only be available when you use an installer - which again wasn’t was has been done when just copying the tool.
