Apple's developer website has been down for days, and the company has just confirmed in an email that "an intruder" attempted to access personal information from its registered developers. In the email sent to its developers, Apple writes that "sensitive personal information was encrypted and cannot be accessed." But despite the claim that no sensitive information was stolen, Apple warns that some developers may have had their names, mailing addresses, and email addresses accessed in the breach.

During the downtime, Apple indicated that the site was undergoing maintenance, but did not address malicious activity — leading some developers to question if the site had been hacked. As Neowin reported on Saturday, some developers indicated on Twitter that they had received password reset emails from Apple, fueling speculation that the site had been compromised.

In response to the intrusion, Apple says that it is "completely overhauling" its website, including its developer systems, server software, and database. "We apologize for the significant inconvenience that our downtime has caused you," Apple writes, "and we expect to have the developer website up again soon."

We've asked Apple to comment on the intrusion and to clarify the steps it is taking to resolve the issue.

Apple's full email to developers can be read below:

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.

Thanks, Ben!
