In January, a number of Apple employees had their Macs compromised following visits to the popular iPhoneDevSDK forum. Employees from Facebook and likely dozens of other companies were compromised as well. In a blog post today, site owner Ian Sefferman shared some limited details* about what happened and what the site is doing about it.
Most notably, the attack was reportedly ended by the hacker on January 30, 2013, meaning the site believes that there is no ongoing threat.
What we've learned is that it appears a single administrator account was compromised. The hackers used this account to modify our theme and inject JavaScript into our site. That JavaScript appears to have used a sophisticated, previously unknown exploit to hack into certain user's computers.
We're still trying to determine the exploit's exact timeline and details, but it appears as though it was ended (by the hacker) on January 30, 2013.
As with Facebook, it's important to stress that we have no reason to believe user data was compromised.
Eric Romang has done some additional detective work on the the attack, laying much of the blame on Java itself. Last month, Apple twice blocked Java 7 from working on users' Macs, perhaps after the company discovered that its own machines had been compromised.
