Ok an update on my little adventure:
I mailed him, no reply.
I dug up another harddrive on which I will set up a new Linux and =
meanwhile I can plug in the old "corrupted" hdd to keep the show running =
before I finalize the new setup. Currently I'm playing around with RH7, =
but the memo from the GCC developers stating that RH7's gcc is only a =
development version makes me a little uneasy about it. What's the scoop?
When I set up that box originally, I figured "well, who would want to do =
something with it, it's just a plain gateway box?". But over the months =
it grew, I put on apache, php, mysql, GnuPG, SMB and used it as =
development server for my sidejobs. Also I set up subdomains for my kids =
and what not... now I have to set it all up again and it's a royal PITA.
I plan to run too many services on it to be really secure, but I will =
nevertheless tighten things up a bit. FTP will go for sure. I guess I =
rather log in remotely via SSH and ftp manually from there. I'm also =
will take some closer looks into "Maximum Linux Security" which I picked =
up a while ago. My firewall rules were a bit liberal too...=20
Another thing I'd be interested in is some form of automatized backup of =
certain directories. I don't have a backup drive at the moment and I =
don't really want to run another electricity hogging PC constantly which =
could suck down files with 'expect' or similar... anybody got ideas?
Now some more details about my corrupted box & that cracker.
Whatever he wrote about that he didn't damage anything, just deleted the =
logs and changed some html-files doesn't sound any likely. HE created a =
new user "skizzo", some more usergroups and pseudo-legit accounts. =
Judging from the remaining files in a directory ".stuff" in =
/home/skizzo/, he installed one or more bots in the system. Looking into =
cron.d and rc.d showed all kinds of weird stuff called.
I also found a .gz and programs called "adore" and "ava". Ava seems to =
be a program to hide tasks so they don't show up with "ps" anymore and =
something else weird it seems to to with PIDs. Adore does some other =
little thingies...
from ava.c:
printf("Usage: %s {h,u,r,i,v,U} [file, PID or dummy (for =
'U')]\n\n"
" h hide file\n"
" u unhide file\n"
" r execute as root\n"
" U uninstall adore\n"
" i make PID invisible\n"
" v make PID visible\n\n", argv[0]);
If anybody wants those programs to play around with them... just lemme =
know.
Well, bottomline is that I absolutely will set up a new OS and will =
tighten security a little. Since I was an easy target once as it seems, =
I can expect more to come, right?

it? Anyone know? I know almost nothing about hacking/hackers/etc...

Someone hacked into my little Linux gateway box. He defaced =
index.html and saved the old one as old.html
That he appears as root/ftp, is that an indication how he got in?
I had anon. ftp running, using the default one RH 6.2 ships with =
(wu-2.6.0).
I suppose I have to completely re-setup that box, I just would like =
to know what hole to close there.
Any ideas?
If anybody wants to see the deface before I fix by box: =
