This years Blackhat 2013 conference started off with a surprisingly detailed presentation from General Keith Alexander on his recently exposed programs. Unfortunately, there werent terribly many technical details or discussion of technical details. The presentation included screenshots of what looked like a Windows XP GUI that an analyst would see when examining phone call metadata. Other interesting talks included reviews of UEFI and BIOS level attacks, with bootkits and rootkits on Windows 8 systems demonstrated. No 0day was publicly dropped at any of the talks this year.”]
