A tipster told us that SourceForge had been hacked yesterday, with the site unavailable for part of the morning, so we pinged people at the open-source code repository to see what went down. Says Ross Turk, the site's "community manager":

Hey, Jordan! Your tipster's accurate. We played a game of cat and mouse with a "security enthusiast" from Europe yesterday. :) No harm done, though, and everything's running smoothly.

Yesterday's incident wasn't the first hacking attempt on SourceForge. Last year, users were told to change their passwords. And suppose that the next intruder is more than just enthusiastic? If really talented hackers broke in, would we even know what they changed in the code? A chilling thought.
