Some ‘Tards Hacked Me!

Some group attacked my website :(
Not this one, thankfully, but there was an attack on a *previously unknown* vulnerability on my website, caused by Wordpress’s auto installer making a wp-config file with permissions 666, which enabled it to be attacked, apparently.
Once again, BizStreet responded quickly and helpfully, and we found the source of the problem in minutes.
The hacking group were called Mir*aTu*rk (-*)(Google it, I’m not linking to them after the attack they caused on me), and they appear to have done it to loads of websites so beware, I guess.
I’m also wondering if there is anything I can do to return the favor, it seems like script-kiddies playing with some script that finds vulnerabilities, and I’m sure as hell going to make sure I harden GPearce against it now, and so on and so forth. What is there that’s legally possible to do, to return the favour? Comments appreciated
