There must be some new worm or virus of some sort out there. As you can see if you scroll down a bit, I've written a dictionary defence program. I've been running this on my FreeBSD firewall for quite some time now and the though I've seen a few spikes in number of attacks per day, I've not seen anything like this before. Normally, I block about an average of one or two IPs a day from attacks being run on the 2 machines that I have with exposed SSH. Over this past weekend, I've seen 70 different IPs get busted. Quite a lot of action for a home network.
