Apple Inc.'s developer site has been unavailable for software engineers after a hacker tried to steal personal information, the company said Sunday.
Apple took the website, used by programmers who write applications for iPhones, Macs and other products, offline on Thursday to fix the issue, the company said in a statement posted on the Internet.
Developers who use the site for software downloads, documentation and engineering information could face delays in introducing their own products. Some of the information is encrypted and Apple has not been able to rule out whether names, mailing addresses or email addresses were accessed, the company said.
"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," Apple said in the statement. "We apologize for the significant inconvenience that our downtime has caused you and we expect to have the developer website up again soon."
Apple said it will extend memberships for any users if their accounts are due to expire while the website is offline.
The Pentagon cleared Apple devices for use on its networks in May, approving the use of government-issued Apple products running a version of the iOS 6 mobile platform.
