A Turkish security researcher has claimed he is responsible for hacking Apple's developer portal last week. In a comment posted on TechCrunch, Ibrahim Balic says that he reported 13 bugs to Apple. But in a reaction to Apple's lack of response he sent the user details of 73 Apple staff he was able to extract from the site. He claims to have personal information for in excess of 100000 users.
There's a private YouTube video where he claims to expose the method he used and other "sensitive" information.
Although the site is back up now, we'd suggest changing your password if you have a developer account.
We contacted Apple and a spokesperson said that Apple would not be making any official comment regarding this incident.
