The number of vulnerabilities in firmware disclosed as affecting Wintel PC vendors has been rising over the past few years. Although several attacks have been presented against Mac firmware, unlike their PC counterparts, all of them required physical presence to perform. Interestingly, when contacted with the details of previously disclosed PC firmware attacks, Apple systematically declared themselves not vulnerable. This talk will provide conclusive evidence that Mac's are in fact vulnerable to many of the software only firmware attacks that also affect PC systems. In addition, to emphasize the consequences of successful exploitation of these attack vectors, we will demonstrate the power of the dark side by showing what Mac firmware malware is capable of. Speaker Bios: Trammel Hudson enjoys taking things apart and understanding how they work. He presented the Thunderstrike firmware vulnerability at 31C3, created the Magic Lantern firmware for Canon cameras, and teaches classes at the Brooklyn hackerspace NYC Resistor.

To combat such attacks he researches trusted computing systems that can provide much stronger security guarantees than normal COTS. He co-founded LegbaCore in 2014 to help improve security at the foundation of computing systems. He is also the founder and lead contributor to OpenSecurityTraining.info. He has posted 9 full days of class material material on x86 assembly, architecture, binary formats, and Windows rootkits to OpenSecurityTraining.info.
