How to Keep WordPress Secure
From a tweet by @wordpress:
A stitch in time saves nine. I couldn’t sew my way out of a bag, but it’s true advice for bloggers as well — a little bit of work on an upgrade now saves a lot of work fixing something later.
The tactics are new, but the strategy is not. Where this particular worm messes up is in the “clean up” phase: it doesn’t hide itself well and the blogger notices that all his links are broken, which causes him to dig deeper and notice the extent of the damage. Where worms of old would do childish things like defacing your site, the new ones are silent and invisible, so you only notice them when they screw up (as this one did) or your site gets removed from Google for having spam and malware on it.
