A ransomware named "Want to Cry" has attacked more than 150 countries and regions in the world since May 20 12, and its affected areas include government departments, medical services, public transportation, postal services, communications, automobile manufacturing and so on.

Including Microsoft and Splunk network security company, the industry generally believes that the "crying" virus originated from the virus database of the National Security Agency. Last month, the National Security Agency suffered a leak, and the hacking tools it developed were made public.

The Associated Press commented that in this global attack, hackers did not independently develop the "want to cry" virus, so the US National Security Bureau is hard to blame.

Many people accuse the U.S. government of knowing Microsoft's security vulnerabilities, but failing to inform Microsoft in time. It is to hoard attack tools and let leaks endanger the whole world. The American Civil Liberties Union called on Congress to pass legislation to force the U.S. government to inform IT companies of security vulnerabilities in time so that these companies can take remedial measures in time.

In addition, some cyber security experts criticized that the United States invested heavily in developing hacking tools instead of self-defense mechanisms, which made the global network environment "more unsafe". According to data released by the federal government of the United States, 90% of the expenditure on network projects in the United States is used to develop hacker attack weapons.
