The BSides Canberra delegate badge code
There are 3 parts to the BSides badge code.
-
The BadgeCodeGenerator which generates header files and lookup tables used by the badge. Two things are created - the sine and cosine lookup tables which are used by most of the demo effects. And secondly, a compressed BMP image stored as a C array.
-
The server component which gathers tweets with the hashtag #BSidesCbr and makes it available as a text-based web page. The physical badges will connect to this server and collect content.
-
The code that gets flashed to the badge.
If the badge cannot see the SSID BSidesCTF, then it will not connect to the badge network and therefore not have network functionality.
