We got an automated notice from one of the big search engines that both 
http://ftpmirror.your.org and http://dumps.wikimedia.your.org were hosting some 
unspecified malware. I've verified nothing on the mirror box itself is 
compromised from the best I can tell, which leaves them being unhappy with 
something that we're mirroring.

I've started ClamAV scanning the whole public volume, but that's going to take 
quite a while (+20 million files, 80TB of data). The only thing it's complained 
about so far is:

http://ftpmirror.your.org/pub/wikimedia/images/wiktionary/fj/c/c4/citibank-car-loan.pdf

which was making the scanner crash. I don't see anything wrong with the file 
itself though.


Is it possible someone could have uploaded something at one point that was 
malicious and it's still floating around in the archives that got pushed to us?
