# Fe2O3
|
||||
Simple prepender virus written in Rust
|
||||
# Linux.Fe2O3
|
||||
|
||||
This is a POC ELF prepender written in Rust. I like writting prependers on languages that I'm learning and find interesting.
|
||||
|
||||
# Build
|
||||
```$ cd src
|
||||
$ 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.
|
||||
|
||||
# Binary Sample
|
||||
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
|

$ sha1sum Linux.Fe2O3

This is a ELF prepender written in Rust by TMZ (2019).

|

Linux.Fe2O3 (September 2019) - Simple binary infector written in Rust.
|
||||
This version encrypts the host code with a simple XOR and decrypts it at runtime.
|
||||
It's almost a direct port from my Nim infector Linux.Cephei and Go infector Linux.Liora.
|
||||
|
||||
Build with: rustc main.rs -o Linux.Fe2O3
|
||||
|
||||
Note that Rust version used was rustc 1.37.0 (eae3437df 2019-08-13).
|
||||
It has no external dependencies so it should compile under most systems (tested under x86_64).
|
||||
It's also possible to adapt it to be a PE/Mach infector and compile under Windows/macOS.
|
||||
|
||||
Use at your own risk, I'm not responsible for any damages that this may cause.
|
||||
A big shout for those who keeps the scene alive!
