Spear-phishing attacks out of China targeted Google, Adobe, and more than 20 other U.S. companies. Attackers used intelligence, custom malware to access Google and Adobe systems, experts say. The attacks were primarily going after source code from many of the victim firms, they say. Microsoft appears to be in the clear: “We have no indication that any of our mail properties have been compromised,” a Microsoft spokesperson says. Google says attackers’ primary goal was to access the Gmail accounts of Chinese human rights activists.”]
