The core of this stage involved crafting a precision payload that aligned with the program's expectations of the turtle structure while redirecting the instruction pointer.
The "Turtles" challenge involved a program that processed nested structures (turtles). Each "turtle" contained pointers to other turtles, creating a complex chain. The objective for Part 2 was to transition from the initial memory leak (achieved in Part 01) to a controlled "magic gadget" execution. Technical Analysis LetsSplitTurtles.part02.rar
: By placing a magic_gadget address at a specific offset ( +0x60 ), the program was forced to execute the desired shellcode or function when it attempted to traverse to the "next" turtle. Execution & Debugging The core of this stage involved crafting a
: A 64-byte ( 0x40 ) buffer of null bytes provided a safe landing zone for the program's internal processing. The objective for Part 2 was to transition

: The payload specifically targeted RDX and RAX to set up the final call.
: The first 16 bytes of the payload were used to point the RDI register toward a "slack" space in memory.
