New paper: 23c3 slides about firmware analysis are online as well.
Note about UWfirmforce: I realize just now there are minor issues with the release:

• signature-matching plugins without an analysis callback are ignored, change plugin.c line 99 from "return -1" to "return 0" to fix that (currently concerns ELF, FAT, ROMFS and ZIP)
• the plugins need to be installed in /usr/local/lib/UWfirmforce to be found (unless you define PLUGINDIR at compilation time)
• on Linux you may have to compile with LDFLAGS="-l dl"

I apologize for the inconvenience, and will release an updated version in the days to come.
