Linux.Devnull is a worm that, like Slapper, uses the OpenSSL vulnerability on Apache servers. However, its mechanisms are rather different. Read more about it here.
In related (old) news, think it's nifty that f-secure joined the Slapper peer-to-peer and is graphing infected machines in real-time.
I'm still not really here, folks. Hope to get net access up and running at home by next week. Hope you are all well and happy :)
