The New York Times reports that Mac computer users at Apple and Facebook were most likely infected by malware when they visited an online forum for software developers.
The compromised site, iPhoneDevSDK, is an online forum designed for software developers. The site is still infected, and visiting it is not recommended.
It is unknown at this time if the website itself had any involvement in the attacks, but it is likely the work of outside parties, given the site’s reputation as a dedicated community for iPhone developers.
Apple had announced that a small number of their employees had been infected through a Java plug-in vulnerability. The issue was fixed by a Java update that Apple released Tuesday afternoon.
Mac users will be able to detect if they have been affected by the security flaw by installing the Java update, which will notify the user if malware is found.
The Next Web reports that iPhoneDevSDK is currently in maintenance mode.
