About CableProbe

What CableProbe is — and is not
CableProbe helps you analyse an unknown USB-C-to-USB-C cable in a controlled environment and collect evidence that may indicate unexpected or potentially malicious behaviour: hidden HID devices, network gadgets, mass storage, serial channels, transient enumeration, kernel errors.
CableProbe only observes, records and reports. It does not inject payloads, exploit anything, capture credentials, establish persistence or provide remote access. It is a monitoring tool for a sacrificial test host.
CableProbe cannot prove that a cable is safe or uncompromised. A clean report means CableProbe did not observe anything notable during that session, not that the cable is benign. Use it as one input to your own judgement.
