A number of Macs owned by Apple employees were compromised by the same China-based hackers that targeted Facebook employees recently, reports Reuters. The news agency says Apple disclosed the breach to its reporters. Apple, which is working with law enforcement to track down the hackers, told Reuters that only a small number of its employees' Macintosh computers were breached, but "there was no evidence that any data left Apple." The iPhone and iPad maker said it would release a software tool later on Tuesday to protect customers against the malicious software used in the attacks.The New York Times
