Re: spyware on OS X



Just FYI, the script making the rounds that causes these log entries is this one:
http://www.k-otik.com/exploits/08202004.brutessh2.c.php


It's got a small 2,000-word dictionary in this iteration. It would be prudent for everyone with SSH enabled on OSX to scan the list and make sure you aren't using one of the passwords in the list. I personally get several scans a day on my home server from people that appear to be using this script.

Hi,
I don't have any indications of such hacking activity, probably because I use Mac OSX's built-in software firewall. I suppose it would be obvious? What are the messages that make you think you're being guessed at? Something like "attempt to log in as root failed due to too many attempts?
Just curious about what's out there. Thanks.
