Introducing the Manifold - Triple USB Ethernet Dongle
I got tired of carrying a bunch of USB Ethernet dongles for my pentests. Whenever I need to connect to multiple networks, my laptop ends up looking like a degenerate squid monster. It was time to do something about this. Meet the Manifold The Manifold features three individual 10/100 Ethernet interfaces, each with its own MAC address. Connect to all the networks without turning your computer into a spaghetti creature! These are shipped with MAC addresses from the Ringtail Security prefix - read more about it here. Customizable by default As always, the STL files for the plastic case are...
Ringtail Security has a MAC prefix!
The time has finally come! With the development of new products (in particular those revolving around Ethernet), the need is growing for Ringtail Security to be able to create MAC addresses. I must admit this is something I've been dreaming about for the past 15 years. The IEEE SA In case you are not familiar, MAC addresses are created by manufacturers within specific ranges allocated by the Institute of Electrical and Electronics Engineers Standards Association (IEEE SA) Registration Authority. To be able to create such MAC addresses, manufacturers use a MAC prefix assigned by the IEEE SA. Ringtail Security's first block...
A clip-on cover for the Netsplit
Is your Netsplit tearing up the pockets of your delicate suits while on assignment? Well, you are not alone! I must admit I have been experiencing the same issue myself. This prompted me to design a small cover for the back of the Netsplit - just enough to protect the exposed pins (or rather, protect your clothes from them). After a bit of playing around in Fusion 360, I had exactly what I wanted. I started from the actual PCB outline layer, which I exported as DXF - a format which can be easily imported in Fusion. Printing the result on...
Introducing Netsplit: a pocket-sized passive Ethernet tap
Meet the Swiss pocket knife of network traffic inspection Netsplit is a passive Ethernet tap device, making it easy to sniff packets across Ethernet links. Place the Netsplit between two devices and monitor network traffic on the tap ports. This works by forcing the devices into 10/100 mode (prohibiting gigabit-speed comms) also known as "Fast Ethernet", which is well suited for passive monitoring. The two ports at the ends of the Netsplit are wired together normally as would a standard cable. However, their respective transmission lines are mirrored to the center "tap" ports. Because only the transmission lines are mirrored to...
