This is a POC ELF prepender written in Rust. I like writting prependers on languages that I'm learning and find interesting. As for the name, Fe2O3 is the chemical formula of Rust, I thought it was appropriate.
$ rustc main.rs -o Linux.Fe2O3
Note that the Rust version used is rustc 1.37.0 (eae3437df 2019-08-13), the latest at this moment.
A binary sample is also available at https://www.guitmz.com/Linux.Fe2O3
$ file Linux.Fe2O3
Linux.Fe2O3: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, with debug_info, not stripped
