The terms "WannaCry," "Petya," and "EternalBlue" are related to cyber attacks. These terms represent specific types of malware and hacking techniques that have been in the news recently.

WannaCry is a type of ransomware that spread globally in 2017, infecting computers and encrypting their files. It demanded a ransom to be paid in cryptocurrency in order to restore access to the files.

Petya, also known as NotPetya or ExPetr, is another type of malware that emerged in 2017. It also encrypted files on infected computers but had additional features that allowed it to spread rapidly across networks.

EternalBlue is an exploit developed by the U.S. National Security Agency (NSA) that was leaked and later used as a method to propagate malware, including WannaCry and Petya. It targets vulnerabilities in the Microsoft Windows operating system.
