iPhoneDevSDK—the site apparently responsible for the hacks at Facebook, Apple, and Twitter—says it was not aware it was being used to attack visitors until it read press reports this week. In a news post (do not click if you're wary of security breaches) on Wednesday, site admins said they had no knowledge of the breach and were not contacted by any of the affected companies. Though, iPhoneDevSDK is now working with Facebook's security team in order to share information about what happened.
"We were alerted through the press, via an AllThingsD article, which cited Facebook. Prior to this article, we had no knowledge of this breach and hadn't been contacted by Facebook, any other company, or any law enforcement about the potential breach," wrote iPhoneDevSDK admin iseff.
"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," he went on. "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."
