Fuld version: Simpel Bruteforce test
Du ser lige nu en skrabet udgave af vores indhold. Se den fulde version med ordentlig formatering.
Brug denne simpel test til at se om din server tager forhold til bruteforcing.
Scriptet kræver NodeJS, og bibliotek: simple-ssh og randomstring, som kan installeres via npm install simple-ssh og npm install randomstring

Kode:
/*
Use this test for seeing the important logs of bruteforce attacks in /var/log/auth.log .
Please use this on own risk!! If your linux box got the security, you might get banned from your own linux box.

Use this as a tester for auto-blocking robots that are trying to bruteforcing into your SSH.

libraries used: simple-ssh and randomstring.
