What is Wanna Cry ransomware?

WannaCry ransomware is a type of malicious software that encrypts files on a computer, making them inaccessible, and then demands a ransom in exchange for decrypting the data. It gained widespread attention in 2017 for its rapid global spread, affecting organizations and individuals worldwide.

One key difference between WannaCry and other ransomware variants is its use of an exploit called EternalBlue, which was developed by the U.S. National Security Agency (NSA) and leaked by a hacker group known as the Shadow Brokers. This exploit targeted a vulnerability in Microsoft Windows systems, allowing WannaCry to spread rapidly across networks without requiring user interaction.

Additionally, WannaCry had a worm-like capability, enabling it to self-propagate within networks, unlike many ransomware strains that typically rely on user interaction, such as clicking on malicious links or opening infected email attachments.

Overall, WannaCry’s combination of rapid global spread, use of a leaked government exploit, and worm-like behavior set it apart from many other ransomware variants in terms of its impact and propagation methods.
