Interestingly, 1 server is running Linux, the 2 others running Netware. Sounds like someone's password got compromised.
Where is that information coming from? Novell's PR has been working overtime to keep these incidents firmly under the rug.
If you read the machine names that were allegedly hacked you see that they are a wiki machine and a forge machine.
Wiki is MEANT to be a community authoring system where anyone can post. Hacking a wiki is like writing on the sidewalk with chalk, no one can stop you, but anyone can piss on what you wrote ad any given seconds.
Forge is like source forge, where you can all post but its tighter controlled than a wiki.
Synopsis: Yawn. Move along folks, nothing to see here.
Or gave it to a "friend".
The vast majority of Novell's development is done offshore. To be compromised by offshore help would be icing on the cake.
