“May was a grim month for American cybersecurity. First, the Obama administration accused China of hacking government computers, potentially to exploit weaknesses in the US military. Then, US officials announced that hackers, believed to be sponsored by the Iranian government, had successfully broken into computer networks that run US energy companies, giving Iran the means to sabotage power plants. This week, the Washington Post reported that Chinese cyberspies had hacked more than two dozen big-name US weapons programs, including the F-35 fighter jet, an army program for downing ballistic missiles, and the Navy’s Littoral Combat ship. Not all cyberthreats are equal, but one question remains: Who poses the greater danger—Chinese or Iranian hackers?”
