21 // This class scans for "MalayBouncer ver2.0 by CrazyBandit Co. Ltd."
22 // (thanks puppet for the info). It's not a misconfigured proxy but a trojan
23 // (mIRC script) that can act like a proxy. Although there is a generic
24 // password, I decided to not check it as such a bouncer on port 407 shouldn't
25 // really exist anyway.
