Information about Bitburner is still incomplete. Please help us fill the details of the game using this contact form.

Here is a simple script, that can be started at any moment of the game. It will buy servers, find all accessible servers, open ports, nuke, find target servers, hack, grow, and weak servers. And will do it again and again.
