EternalBlue [5] is a computer exploit software developed by the U.S. National Security Agency (NSA). [6] It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network .
EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end of life .
The Shadow Brokers (TSB) is a hacker group who first appeared in the summer of 2016. [1] [2] They published several leaks containing hacking tools, including several zero-day exploits, [1] from the "Equation Group" who are widely suspected to be a branch of the National Security Agency (NSA) of the United States.

In 2015 Kaspersky's research findings on the Equation Group noted that its loader, "GrayFish", had similarities to a previously discovered loader, "Gauss", from another attack series, and separately noted that the Equation Group used two zero-day attacks later used in Stuxnet; the researchers concluded that "the similar type of usage of both exploits together in different computer worms, at ...
In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability.It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
