EternalBlue

Computer security exploit

EternalBlue is a computer exploit software developed by the U.S. National Security Agency (NSA). It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network. The NSA knew about this vulnerability but did not disclose it to Microsoft for several years, since they planned to use it as a defense mechanism against cyber attacks. In 2017, the NSA discovered that the software was stolen by a group of hackers known as the Shadow Brokers. Microsoft was informed of this and released security updates in March 2017 patching the vulnerability. While this was happening, the hacker group attempted to auction off the software, but did not succeed in finding a buyer. EternalBlue was then publicly released on April 14, 2017.
