There's a lot of ways this can happen, it's impossible for us to tell you what exactly caused it.
Here's a few guesses:
- Outdated vBulletin forum
- Vulnerable plugins
- Other vulnerable software on your server

You need to find the cause first before you can implement something to prevent it from happening again in the future.
