Hello I have no suggestions whatsoever as to what they were thinking but i'll translate the strings. Im pretty sure it won't help at all as i'm convinced it was just a "routine" attack but here it goes...

However, recently a webserver that I do minimal administrative work for was attacked. We're still unsure exactly what had been done. Most of the logs have been either cleaned or wiped completely (either by log rotate or by the attacker). I was gone for the weekend so I sorta came back to this. I don't really have questions about the attack per se, we're doing pretty well at the recovery process.... one question I do have however is this. > > The attacker (either manually or using a program) replaced all index.html/htm and index.php files they had permission to replace with a UDP flooder. I extracted some of the information from the flooder using the strings program and heres what I get: > > !HELP! beta version. //TRANSLATION: > !HELP! > !HELP! #brazil@efnet - eleet team > !HELP! + code by bonny ::: [email protected] > > !CREDITS! * creditos aos amigos e a quem me ajudou. //TRANSLATION: credits > to friends and those who helped > !CREDITS! > !CREDITS! * none ([email protected]) ::: Brazil > !CREDITS! packet spoof > !CREDITS! * cyclone ([email protected]) ::: Brazil > !CREDITS! parceiro das hackadas, aprende rapido //TRANSLATION: hack > partner, learn fast > !CREDITS! * mariana ([email protected]) ::: Brazil > !CREDITS! minha leet girl, exclusiva :) //TRANSLATION: my leet girl > !CREDITS! * alcaloide ([email protected]) ::: Brazil > !CREDITS! super lamer, versao 3 pra pacotar ele ////TRANSLATION: super > lamer, version 3 to pack(et) him > > * Opcao invalida! * %s para maiores informacoes. //TRANSLATION: invalid > option %s for more info > > !AJUDA!: %s -help > > CREDITS: %s -credits > > !USAGE!: %s (host/ip) (size) (loops) > > (host/ip) == host do babaca a ser fudido. //TRANSLATION: host of idiot to > be f*ck*d > (size) == bytes a serem enviados. //TRANSLATION: send these many bytes > (loops) == tempo da fudecao/s. //TRANSLATION: total time of f*ckerying > > CTRL-C - ACAO CANCELADA! //TRANSLATION: action cancelled > > FUDEDOR (v3.0) by bonny - PRIVATE!@#! //TRANSLATION: FUC*ER v3.0 by bonny > host desconhecido: %s //TRANSLATION: unknown host > Maximo de bytes permitodos: 65535. //TRANSLATION: maximum allowed bytes > > A maquina nao tem memoria suficiente. //TRANSLATION: Not enough memory in > machine > > FUDENDO A VERA %s COM %s bytes... //TRANSLATION: f*cking VERA %s with %s > bytes > > pronto maneh, o babaca foi fudido! :) //TRANSLATION: that's it, <name>, > the idiot was f*cked > > > > My question to anyone out there who can answer it is this, do you know of any kind of automated attack that replaces index files for websites with such a flooder? It doesn't seem like this hack was extremely well thought out, or done by anything more than a script kiddy... if it was, why would they replace these files with this binary program? Why not replace it with a new index.html file saying we got hacked?
