Secure your rsync shares, please.

Thursday, 13 February 2014

Recently I started doing a internet-wide scan for rsync servers, thinking it might be fun to write a toy search-engine/indexer.

Even the basics such as searching against the names of exported shares would be interesting, I thought.

Today I abandoned that after exploring some of the results, (created with zmap), because there's just too much private data out there, wide open

IP redacted for obvious reason:

shelob ~ $ rsync  rsync://xx.xx.xx.xx/
ginevra        	Ginevra backup
krsna          	Alberto Laptop Backup
franziska      	Franz Laptop Backup
genoveffa      	Franz Laptop Backup 2

Some nice shares there. Lets see if they're as open as they appear to be:

shelob ~ $ rsync  rsync://xx.xx.xx.xx/ginevra/home/
drwxrwsr-x        4096 2013/10/30 13:42:29 .
drwxr-sr-x        4096 2009/02/03 10:32:27 abl
drwxr-s---       12288 2014/02/12 20:05:22 alberto
drwxr-xr-x        4096 2011/12/13 17:12:46 alessandra
drwxr-sr-x       20480 2014/02/12 22:55:01 backup
drwxr-xr-x        4096 2008/10/03 14:51:29 bertacci
..

Yup. Backups of /home, /etc/, and more.

I found numerous examples of this, along with a significant number of hosts that exported "www" + "sql", as a pair, and a large number of hosts that just exported "squid/". I assume they must be some cpanel-like system, because I can't understand why thousands of people would export the same shares with the same comments otherwise.

I still would like to run the indexer, but with so much easy content to steal, well I think the liability would kill me.

I considered not posting this, but I suspect "bad people" already know..,
