Binary Hacks - on inspecting a binary (ELF)

§ dump process virtual memory

  1. get [pid] of process
  2. get the memory mappings cat /proc/[PID]/maps
  3. identify the memory range of interest
  4. connect gdb to pid and dump memory:
# perhaps need sudo

gdb --pid [PID] 
> dump memory <PATH-TO-DUMP-FILE> [START_ADDR] [END_ADDR]

Then you can exam the dump with tools like hexdump.

§ readelf: get symbols from a specific section

# replace <program> with your binary, and <n> with the section's Ndr shown in
# readelf -S.

readelf -Ws <program> | awk '$7==<N>{print}
