Hardware Router CTF

Here at Pen Test Partners we love hardware and also love a good CTF. So here's how I figured out my way through the hardware CTF that PTP set as a pre-requisite for some interviews. I'm pretty new to hardware, so learned quite a bit along the way. We have now moved on to a new 'interview' CTF so,...

Information Disclosure

Apache gateway-spi is vulnerable to information disclosure.
