Maybe some of you already notices that the developer section on Apple’s website has been offline for a while for “maintenance”. However in an email to developers, Apple revealed that its Developer Center website was breached by unknown hackers and was taken offline last Thursday as a precaution. Apple notes that sensitive personal information was “encrypted and cannot be accessed” but that Apple’s engineers “could not rule out the possibility” that developer names, mailing addresses and email addresses may have been accessed.

Last Thursday, an intruder attempted to secure personal information of our registered developers from our developer website. Sensitive personal information was encrypted and cannot be accessed, however, we have not been able to rule out the possibility that some developers’ names, mailing addresses, and/or email addresses may have been accessed. In the spirit of transparency, we want to inform you of the issue. We took the site down immediately on Thursday and have been working around the clock since then.

In order to prevent a security threat like this from happening again, we’re completely overhauling our developer systems, updating our server software, and rebuilding our entire database. We apologize for the significant inconvenience that our downtime has caused you and we expect to have the developer website up again soon.

If your program membership was set to expire during this period, it has been extended and your app will remain on the App Store.

It is unknown when the site will be back online, but Apple said it expects to have it up again soon.
