A large number of websites created using WordPress have been hacked in the past few days. The attack initially appeared to be limited to web sites hosted by DreamHost, but it has since become apparent that blogs hosted at GoDaddy, Bluehost and Media Temple have also been affected.

Experts are still puzzled over which hole was actually exploited for the large-scale attack.”]
