This may seem daft but watch the video. if the usb stick or the cable simulates a keyboard why not a rpipico usb to detect a keyboard. it wouldn't detect a usb memory stick.. so if it detects a kb then it's bogus?? https://www.youtube.com/watch?v=e_f9p-_JWZw&t=141s https://www.youtube.com/watch?v=mPF9f-PLDPc |

Do you mean connect the suspect USB stick to a pico to see if it comes up as a kb? And if it does then don't connect to a PC? Sounds sane. Might not work if a fake stick can tell it's not connected to a PC so it decides not to be a kb - but I don't know if that's possible. John |

I think it uses say win or linux but says it will find os. if it sets up as hid then pico might see it as a keyboard, not connected usb mem to picousb as maybe damage. |

A friend of mine once saw a mouse at a security training course many years ago that started coding as soon as the light was switched off. Only then did it register as a keyboard and program viruses... Frank |

sounds like what we need is a means to tell the operating system to exclude any keyboards other than those plugged into a specific USB port. after all, once set up how often do you want to move your wired or wireless keyboard from one USB port to another? cheers, rob :-) |

Want a secure system? Run a Nascom 2 with no outside access. :) I doesn't do anything, but isn't that a small price to pay for security? Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
