ethernet, injection, PoE, Sparkplug -

A delicate situation Sometimes you need to hook something behind a device in a corporate network. Unfortunately, sometimes that device turns out to be an IP phone or video camera only powered through PoE. Unless there's a spare power supply lying around that just happens to match the device, this can mean the difference between a successful intrusion or an embarrassing moment. An easy solution The solution to this is the Sparkplug - a tiny PoE injector capable of powering devices up to 15W. On one side, hook up the included wall adapter and the PoE device. On the other...

embedded, TTL232, UART -

Yes, they still exist... Every once in a while I come across some device that actually talks real RS-232. This is a pain because it means I have to pull out an old USB to RS-232 cable. Most electronics today expose UARTs (serial ports) at TTL levels of 3.3V or 5.0V. This is why the Nautilus USB UART features a switch allowing you to select between these two most common voltages. Simple and versatile I wanted something more versatile than a single-unit USB to RS-232 cable, so I went ahead and designed just the RS-232 to TTL part.  The male pins accept...

3D print, case, embedded, enclosure, microcontroller, Nautilus, shell, UART, usb -

The Nautilus is a dual voltage USB UART - a nice little tool to have whenever you need to pop a shell on some target electronics board, be it a router, embedded Linux system or some microcontroller-based device. Twitter user Rémy GILLET (@remyglt) has taken the time to design a beautiful 3D printed case, which he was then kind enough to share with everyone. The results look very nice, below is a close-up of the orange version printed by @remyglt himself. I quickly printed mine in some glow-in-the-dark PLA, but I must say I still prefer the orange version from Rémy. This is what...

azban, delivery, injection, payload, usb -

The Azban is a great way to compromise systems. Write a few lines of shell script and plug the USB device into a computer to run your payload regardless of operating system or keyboard layout. However, there are many cases where it would be even better to fit the Azban device into a "legitimate" device's enclosure. For this reason, I decided to also offer a Slim version of the Azban device, designed around the form factor for most common commercial USB flash drive enclosures. An example is shown below, fitting the Azban Slim into one of these classic "spinner" style...

Basilisk, Bundesfeiertag, ethernet, lan, NAC, Swiss day -

Once again this year, Swiss National Day celebrations were a great success, as well as the perfect opportunity to enjoy some family time. As always, we also enjoyed the various light shows offered by the city of Gland. The special discount we had last week was also a great opportunity to get some tools for cheap. So much so that by the end of the week the Basilisk had gone out of stock. A few more units have recently been added to the stock, so if you missed it then, this is your chance to get your hands on some...
