Now it seems to be applying the same strategy in the West’s rear area, causing disruptions to online systems and simultaneously benefiting the Chinese economy with viruses and worms used to steal information from computer systems worldwide. The latest simultaneous exploit against thousands of organizations, disclosed on March 2, was dubbed the Microsoft Exchange hack, exploiting servers that manage email systems. The hack allows perpetrators to read messages of selected targets and then venture deeper into infected networks.
Over 60,000 organizations in the U.S. and at least 280,000 users worldwide using Microsoft Exchange for their email were hacked between Feb. 26 and March 3, according to Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency. The organizations include defense contractors, universities, state and local governments, policy think tanks, infectious disease researchers, and businesses: anyone that chose to use Microsoft Exchange for their email service.
