Re: {bb} Infected Linux/BB



Is it possible that your Windows machines have Samba based drive mappings into your Linux box?    I know nimda could propigate through shares like that and would end up all over your Unix machine.
 
I'm sorry if this possibilty was already mentioned - I tuned into this late.
 
I had a Novell server that was polluted with nimda in this manner.  The Novell wouldn't run the nimda logic but it got tons of the eml files dumped on it by the windows hosts that map drives to its storage volumes.
 
I bet there will be a nimda variant that destroys data agressively sometime soon.

I tried to do some more investigation as to what the deal was with Nimba,
I'm not sure where the infection started, but I can say this is a wiley
little bastard. I reported yesterday to have cleaned a majority of my Linux
system off, well I check today and its back again!

I've come to the determination that my entire network needs to come offline
and unfortunately my AV isn't finding the virus, so format/reinstall here I
come.

I just wanted to let everyone know it appears this thing doesn't just attack
windows now.. here is the message I attempted to send last night .. but it
never made it apparently.

Well I got home and did some investigation and here's what I can find and
know for now..

it managed to write to all the bb directories. In addition it wrote *.eml
files to the home directory and every user directory within it. It also
infested the /var directory and everything associated with it (ie sub
directories) but thats it.

I had a firewall running on one of my Windows boxes and I did happen to
notice alot of netbios requests (more then usual) over the last few days, so
its hard to say when this thing attacked my server. I am running apache for
win32 ont his machine and it appears nothing was compromised as was nothing
on my Macintosh or my other 2 windows boxes, one of which had a shared drive
the other did not.

I don't think there was any "damage" done however if bb hadn't emailed me
about it I would have never noticed :)
I'm in the process of cleaning all the files off my box as we speak, I don't
see alot of un-expected traffic so i don't think its scanning a subnet
looking for an IIS hosts, but I can't say that for sure, alot of traffic
comes in and out of this one box, so its hard to track in that respect.

More as I find it.. well lets hope I don't have more to find ;-)
