Apple has released new details (via @cabel) on the security flaw that caused the Developer Center to be down for more than a week, noting via its Apple Web Server notifications page that a "remote code execution issue" was fixed.
On the site, Apple credits 7dscan.com and SCANV of www.knownsec.com for reporting the bug on July 18, which is the same day the Developer Center was taken offline. During the downtime, Apple reported that the Developer Center website had been hacked, with an intruder attempting "to secure personal information" from registered developers. The company noted that while sensitive information was encrypted, some developer names, mailing addresses, and/or email addresses may have been acquired.
The eight-day outage required a complete overhaul of Apple's developer systems and a restoration plan that slowly brought services back online.
While security researcher Ibrahim Balic speculated that he might have been behind the security breach, it is now clear that the issue he reported was unrelated to the major flaw that caused the downtime. Apple credits Ibrahim with reporting a separate iAd Workbench vulnerability on July 22. The vulnerability allowed Balic to obtain both names and Apple IDs of users.
On August 10, Apple reported that all of its developer services were back online, a full 23 days after the outage first occurred. As a result of the downtime, Apple gave all developers a one month extension on their developer memberships.
