The runtime for this command depends on your hacking level and the target server’s security level. In order to hack a server you must first gain root access to that server and also have the required hacking level. A script can hack a server from anywhere. It does not need to be running on the same server to hack that server. For example, you can create a script that hacks the `foodnstuff` server and run that script on any server in the game. A successful `hack()` on a server will raise that server’s security level by 0.002.
