You can write '2' (0x32) anywhere in the filesystem of a Linux-based network switch. How do you get root?
That's basically what my talk at @GrehackConf was about - enjoy!

We're livestreaming the event. In fact, both the venue and I are doing so. Their volume is a little louder, because they're actively monitoring it.
The show must go live !
The live will start at 8:45 AM, get ready ! 🤩
