FireEye released a report showing a significant decline in cyber-attacks originating from China. According to the experts from FireEye attacks from China against the US started declining in mid-2014 and has continued to decrease. The decline in activity can be attributed to several factors such as the Just Departments indictment of several PLA officers believed to have been involved in several high-profile attacks against US military interests. President Xi has made a crackdown on government and military corruption for financial gain and centerpiece of his domestic policies. It is likely that this crackdown has extended to PLA units and their military handlers.”]
