Have posted my tweaks of shark-1.0 (to control the RadioShark v1) to:


I've tweaked the original source code slightly, to work around a couple complaints that GCC generates.  The older version of Fedora is needed as it was the last version to support the older libhid library.

Basically, the above creates a Fedora 25 image that can be called (as a temporary container) to control the white version of the RadioShark (white, v1) device (which can still be purchased via various online markets or from junk-boxes at local social events).  I don't know if it'll work with the black, v2 device but will know shortly, as a friend picked up a v2 device at the Richmond Hamfest.

Still still here

A month goes by fast! Still here, still busy has heck, but it's getting better.

Last week, I participated in the first annual President's Cup CTF. I was able to squeak by, right around the 50th percentile. Not too shabby for a non-pro. Those questions were hard!

This past Saturday, I participated on a team at ODU's CyberOPS 2019 CTF. We ended up in a 4-way tie for fifth place. Although we'd like to do better, we're quite happy with where we placed. Topics we need to brush up on: reverse engineering, image manipulation using GIMP (for the second year), and the more esoteric approaches to SQL injection (A union? Really?).

I'll be demoing the sudo bug (and giving a very short presentation) at this week's Cyber Club meeting. Once again, the media put a bit more OMG into their news articles than was needed, as exploitation of the bug requires a pre-existing "bad idea" in the config file.

I've been improving my Docker containers and have my article tracker (based on Wallabag v1) back online. On the to do list: I'll be needing to grab the source code for the various support libraries, just so a package update doesn't destroy (again) my ability to use the tool.  Will post the source on the school's Docker repository shortly.
