 OSIC\, KU Leuven\n   Lennert is a PhD researcher as the Computer Security 
 and Industrial\n   Cryptography (COSIC) research group\, an imec research 
 group at the KU\n   Leuven University in Belgium. His research interests i
 nclude hardware\n   security of connected embedded devices\, reverse engin
 eering and\n   physical attacks.\n   Twitter: [2]@LennertWo\n\n   Descript
 ion:\n   This presentation covers the first black-box hardware security\n 
   evaluation of the SpaceX Starlink User Terminal (UT). The UT uses a\n   
 custom quad-core Cortex-A53 System-on-Chip that implements verified\n   bo
 ot based on the ARM trusted firmware (TF-A) project. The early stage\n   T
 F-A bootloaders\, and in particular the immutable ROM bootloader\n   inclu
 de custom fault injection countermeasures. Despite the black-box\n   natur
 e of our evaluation we were able to bypass signature verification\n   duri
 ng execution of the ROM bootloader using voltage fault injection.\n\n   Us
 ing a modified second stage bootloader we could extract the ROM\n   bootlo
 ader and eFuse memory. Our analysis demonstrates that the fault\n   model 
 used during countermeasure development does not hold in\n   practice. Our 
 voltage fault injection attack was first performed in a\n   laboratory set
 ting and later implemented as a custom printed circuit\n   board or 'modch
 ip'. The presented attack results in an unfixable\n   compromise of the St
 arlink UT and allows us to execute arbitrary code.\n\n   Obtaining root ac
 cess on the Starlink UT is a prerequisite to freely\n   explore the Starli
 nk network and the underlying communication\n   interfaces. This presentat
 ion will cover an initial exploration of the\n   Starlink network. Other r
 esearchers should be able to build on our\n   work to further explore the 
 Starlink ecosystem.\n\n   '\n\n   1. https://defcon.outel.org/consolidated
