Chinese officials have promised to reveal a secret spying system used by the U.S. government. This comes after investigating a suspected hack of earthquake monitoring gear in Wuhan. China wants to show that the U.S. also spies, as they've been criticized for similar actions. China's investigation involves their National Computer Virus Emergency Response Center and Qihoo 360 internet security company. The information being targeted is about seismic intensity, which can help with understanding terrain, weapons, and nuclear tests.
