Since I was talking about security anyway…. this is a nice toy for breaking open laptops or desktops when the administrator forbade the installation of software, or you want software on it executed. This is often the case with company devices, e.g. the laptops which are supplied by banks to their 3rd party suppliers. Outsourcing is cool, remember?

This is a computer on a stick which can run a Linux kernel. In combination with some USB gadget kernel modules, it can be configured to authenticate itself as any device. All you need to do is plug it in, and iterate by brute force through the device identifiers until you hit one which is accepted to be used. Store the statically linked software you want to install or run on the stick beforehand, and here you go. So if you ever need a SSH client on a “secure” Windows laptop… putty.exe FTW.

USB-C charging cables: not always as good as you’d think

Posted by jpluimers on 2015/12/25

Merry X-mas sorting out your cables (:

Some interesting links that all come down to: make sure your USB-C cable is compliant before you start really using it.

you cannot be sure that cables Benson tested good are always good. Trust me, it happened to me. Knowing the ASINs/EANs of good cables, I went into local stores and bought a number of presumably good cables. Know what? They were bad. Might be that vendors recently changed their cables and there are still batches of bad ones out there, still with the same ASIN/EAN codes. So just be careful!

and

Having a weaker than 3A charger is actually a risk factor because the device being charged will always try to charge at 3 and if the older adapter can’t handle 3A, that is when it might be
