Hardware Attacks, Advanced ARM Exploitation, and Android Hacking

Presented at 30C3 (2013), Dec. 28, 2013, 5:15 p.m. (60 minutes)

In this talk (which in part was delivered at Infiltrate 2013 and NoSuchCon 2013) we will discuss our recent research that is being rolled into our Practical ARM Exploitation course (sold out at Blackhat this year and last) on Linux and Android (for embedded applications and mobile devices). We will also demonstrate these techniques and discuss how we were able to discover them using several ARM hardware development platforms that we custom built. Where relevant we will also discuss ARM exploitation as it related to Android as we wrote about in the "Android Hackers Handbook" which we co-authored and will be released in October 2013.

Lastly, we will also discuss some of our most recent related hardware research (to facilitate the above) which will include bus protocol eavesdropping/reverse engineering, demystifying hardware debugging, and surreptitiously obtaining embedded software (firmware) using hardware techniques. We will demonstrate and show the supportive tools used and techniques developed to perform this work and deploy them against Apple MFI iAP devices, and multimedia devices using OEM implemented USB stacks. (Which will briefly include our experiences around starting http://int3.cc where we sell a fully assembled modified version of a hardware USB fuzzer.)

Along the way we will inevitably share some of the lessons we also learned while completely designing the hardware (from scratch), writing the firmware, and mobile apps for an embedded security device called Osprey that we hold the patent for and have been publicly about publicly as a hardware vulnerability assessment swiss-army-knife for researchers.

  • Stephen A. Ridley
    Stephen A. Ridley is a security researcher and author with more than 10 years of experience in software development, software security, and reverse engineering. Within that last few years, he has presented his research and spoken about reverse engineering and software security research on every continent except Antarctica. Stephen and his work have been featured on NPR and NBC and in Wired, Washington Post, Fast Company, VentureBeat, Slashdot, The Register, and other publications. Prior to his current work Mr. Ridley previously served as the Chief Information Security Officer of a financial services firm. Prior to that, various information security researcher/consultant roles including his role as a founding member of the Security and Mission Assurance (SMA) group at a major U.S. Defense contractor where he did vulnerability research and reverse engineering in support of the U.S. Defense and Intelligence community. Mr. Ridley calls Manhattan home and frequently guest lectures at New York area universities such as NYU and Rensselaer Polytechnic Institute.
