Tags: arm64 


This is a reference to DEFCON 2006’s trivia question which
used EBFE is to x86 as ____ is to PowerPC. This time we have to find the ARM64
A quick
google search tells us that EBFE is a jmp instruction, but ARM does not have
such instruction, they use branches instead, b is our instruction. Looking in
the ARMv8 reference manuals we can see that this refers to EAFFFFFE. This does
not work however as that is the ARM32 variant. Converting to ARM64 we get
14000000. Because ARM64 is also little endian, the answer is 00000014.</span>
