A report by the private cyber-security company Crowdstrike has identified a new PLA Unit as involved in cyber-espionage. It claims that Unit 61486 has for years been systematically breaking into the networks of government entities and companies around the world.  The report says that the N.S.A. and its partners are currently tracking over 20 hacking groups in China and that over half of them are units of the People’s Liberation Army. They are said to be breaking into public and private sector companies ranging from satellite, drone and nuclear weapon component makers to technology and energy companies and research groups. Crowdstrike says that members of PLA's Unit 61486, have in some instances shared computing resources and communicated with members of  the PLA's Unit 61398.
