UPDATE: Turkish hacker posts video of Apple Dev Centre breach

Apple has taken its developer website offline after a hacker attempted to steal personal information from its database.

"An intruder attempted to secure personal information of our registered developers from our developer website," Apple said in a note posted to the member section of its dev website.

That data is encyrpted and "cannot be accessed," Apple said, but "we have not been able to rule out the possibility that some developers' names, mailing addresses, and/or email addresses may have been accessed."

So, Apple took down the site and has "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," the company continued. "We apologize for the significant inconvenience that our downtime has caused you and we expect to have the developer website up again soon."

Apple also informed developers of the breach via email. The Cupertino-based tech titan noted that those whose developer accounts were set to expire during the downtime will have them extended and apps will remain in the App Store.

Back in February, Apple identified malware that affected a small number of Apple employee laptops, though "there was no evidence that any data left Apple," the company said. Upon discovering that intrusion, Apple isolated the infected computers from its network and began working with law enforcement to find the source of the malware.

The breach occurred as Apple is gearing up for the release of iOS 7, which is expected this fall. The company has provided developers with several beta versions of the mobile OS, which overhauls the look and feel of iOS.

Apple is also scheduled to report its latest earnings on Tuesday evening.

UPDATE: A Turkish ethical hacker has claimed responsibility for the breach, posting a video of his exploits on YouTube.

"This is definitely not an hack attack. I have reported all the bugs I have found to the company and waited for approval. I am being accused of hacking but I have not given any harm to the system and i did notwanted to damage [sic]," writes the user Ibrahim Baliç.

He has since told the Guardian, "My intention was not attacking. In total I found 13 bugs and reported [them] directly one by one to Apple straight away. Just after my reporting [the] dev center got closed. I have not heard anything from them, and they announced that they got attacked. My aim was to report bugs and collect the datas [sic] for the purpose of seeing how deep I can go with it."
