## Remarks
RAM cost: 0.1 GB
Function that is used to try and hack servers to steal money and gain hacking experience. The runtime for this command depends on your hacking level and the target servers security level when this function is called. 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 servers security level by 0.002.
## Example 1
```ts
// NS1:
var earnedMoney = hack("foodnstuff");
earnedMoney = earnedMoney + hack("foodnstuff", { threads: 5 }); // Only use 5 threads to hack
```
## Example 2
```ts
// NS2:
let earnedMoney = await ns.hack("foodnstuff");
earnedMoney += await ns.hack("foodnstuff", { threads: 5 }); // Only use 5 threads to hack
```
