Load a statically-linked ELF binary(x86 architecture) without the execve syscall.
After compiling, you can use the
./bin/loader binary to run the dummy programs in
The loader will unpack the elf in memory, map the segments to the right places in virtual memory, resolve symbols and pass execution to the unpacked program's
sample 2 (system commands):
There are more sample programs in the
This is not a shiny tool but rather a tiny PoC code that will (hopefully) help beginners who are trying to learn more about the concept of packers. The loader is compiled with debug info so you can fire-up gdb and step through the C code to see how the magic is done.
It is also a great introduction if you're a researcher who's trying to learn about how the linux kernel loads an elf (which is far more complicated in reality)
