fugu Posted May 26, 2015 Share Posted May 26, 2015 Been thinking about firmware based malware and how difficult it is to "extract" most forms of raw code, once the code is embedded in a device. Makes me think, it might be a great place to hide important data that you want hidden for whatever reason (a password, small file, etc.). Although retrieving it may be difficult ;) Any thoughts?
